<h1><a name="Overview"></a>Overview</h1>
<div class="Body">The localConfig.py file is one of several
configuration
files for GFE. The localConfig
file is optional, and is not provided with the install or
release.
It is added by the field site to override certain features of the GFE
database configuration that are defined in the <a
href="serverConfig.html">serverConfig.py</a>
file.&nbsp; <b><font color="#ff0000">You should NEVER change the
original
serverConfig.py since your changes will be overwritten with the next
upgrade.
See the <a
href="serverConfiguration.html#ServerDatabaseConfigurationModificationOptions">server
configuration overview</a> for information on how to make changes that
are supported to the server.</font></b>
<p>The localConfig.py file can be used to override many of the
definitions
in <a href="serverConfig.html">serverConfig.py</a>, but not all of
them.
This document will describe what you can, and what you cannot
override.
If you need to override an element that is not supported by
localConfig.py
or <a href="localWxConfig.html">localWxConfig.py</a>, then refer to
the
<font color="#000000"><a
href="serverConfiguration.html#ServerDatabaseConfigurationModificationOptions">server
configuration overview</a> for details.</font>
</p>
<p><font color="#000000">The localConfig.py file is not used to
override
the map background definitions, refer to the <a

<hr width="100%">
<h1><a name="AddingYourOwnlocalConfig.pyFile"></a>Adding Your Own
localConfig.py
File</h1>
If you want to make changes to the server database definitions, then
you will want to add your own localConfig.py file. Refer to the <a
href="serverConfiguration.html#LocationofFiles">server
configuration overview file location section</a> for details on
where the localConfig.py file should be located.
<p>The first lines of the localConfig.py <i>must</i> have the
following
format. Failure to do so will not let you refer to any of the
definitions
in serverConfig.py:
</p>
<p><tt>from serverConfig import *</tt>
<br>
<tt>import serverConfig</tt>
</p>
<p>The syntax appearing in localConfig.py varies depending whether you
are adding new definitions, or changing existing definitions.
Typically
when changing existing definitions you will need to prefix the
serverConfig
to the name of the variable. For example,
</p>
<p><tt>var = (a,b,c,d)</tt> refers to a local copy of this definition
and
doesn't override the definition in serverConfig.py
</p>
<p><tt>serverConfig.var = (a,b,c,d) </tt>refers to the variable in the
serverConfig and overrides it.
</p>
<p>The localConfig.py file can be created in the CAVE Localization perspective by expanding
GFE Server->Server Config Files, right clicking on serverConfig.py and selecting Override...

<h1><a name="Testing"></a>Testing Your localConfig.py File</h1>
The recommended way to test your localConfig.py file is to start
EDEX while running a tail command on the /awips2/edex/logs/edex-request-date.log.
If no exceptions result from the changes, you should be fine to proceed into GFE
for further testing.

The following table describes what can be done using a custom

file.&nbsp; If the override capability is marked as "NO" and you still
need the modification, you will need to review <a

<h1><a name="AddinganewWeatherElement"></a>Adding a new Weather Element</h1>
<h4>
Defining the New Weather Element</h4>
You can define a new weather element to add to the Fcst and Official
database,
or add to a new database, or both.&nbsp; You can also use
localConfig.py
to add a new weather element to the model databases, e.g., NAM.
<p>The format of the entry in localConfig.py is identical to that
described
in the <a href="serverConfig.html#WeatherElementConfigurationSection">weather
element section of serverConfig.py</a>.
</p>
<p><a href="EXAMPLElocalConfigAddElement.py">Example localConfig.py file</a>
</p>
<p>The following example defines a relative humidity element with the
following
characteristics:
<br>
&nbsp;
<table nosave="" border="1" width="100%">
<tbody>
<tr>
<td>Element Name</td>
<td>"RH", which defines "RH" at the SFC, this element name may
also be
written "RH_SFC".</td>
</tr>
<tr>
<td>Data Type</td>
<td>SCALAR</td>
</tr>
<tr>
<td>Units</td>
<td>%</td>
</tr>
<tr>
<td>Descriptive Name</td>
<td>Relative Humidity</td>
</tr>
<tr>
<td>Maximum Possible Value</td>
<td>100.0</td>
</tr>
<tr>
<td>Minimum Possible Value</td>
<td>0.0</td>
</tr>
<tr>
<td>Precision</td>
<td>0</td>
</tr>
<tr>
<td>Time Constraints</td>
<td>TC1 (as defined in either serverConfig.py or localConfig.py)</td>
</tr>
<tr>
<td>Rate-Dependent Parm</td>
<td>NO</td>
</tr>
</tbody>
</table>
</p>
<p><tt>rh =&nbsp;&nbsp;&nbsp; ("RH", SCALAR, "%", "Relative Humidity",
100.0, 0.0, 0, NO)</tt>
</p>
<p>Simply defining the new weather element has no affect.&nbsp; You
need
to add it to the Fcst/Official databases or a new database for that
weather
element to truly be created.
</p>
<p>The format of the weather element line is different for WEATHER and
DISCRETE-type weather elements.&nbsp; In particular, DISCRETE type
elements
require a overlapping/non-overlapping flag, as well as the discrete key
definitions.&nbsp; WEATHER and DISCRETE-type elements do not allow
specification
of a maximum possible value, minimum possible value, precision, or
rate-dependent
parm.&nbsp; Here is an example entry for a new discrete element called
SevereWx, which has two possible values, YES and NO.&nbsp; It is
non-overlapping,
since you can't have both YES and NO at the same time. We want an
auxiliary data field with a maximum of 2 characters in length:
<br>
&nbsp;
<table nosave="" border="1" width="100%">
<tbody>
<tr>
<td>Element Name</td>
<td>"SevereWx"</td>
</tr>
<tr>
<td>Data Type</td>
<td>DISCRETE</td>
</tr>
<tr>
<td>Units</td>
<td>cat</td>
</tr>
<tr>
<td>Descriptive Name</td>
<td>Severe Weather</td>
</tr>
<tr>
<td>Time Constraints</td>
<td>TC1 (as defined in either serverConfig.py or localConfig.py)</td>
</tr>
<tr>
<td>Overlapping</td>
<td>NO</td>
</tr>
<tr>
<td>DiscreteKey</td>
<td>YES, NO<br>
</td>
</tr>
<tr>
<td style="vertical-align: top;">AuxDataFieldSize<br>

<td style="vertical-align: top;">2<br>

</tr>
</tbody>

</p>
<p><tt>severewxKeys = [('NO', 'no'), ('YES', 'yes')]</tt>
<br>
<tt>severewx =&nbsp;&nbsp;&nbsp; ("SevereWx", DISCRETE, "cat", "Severe
Weather", NO, severewxKeys, 2)</tt>
<br>
&nbsp;
</p>
<h4>Adding the New Weather Element to the Fcst and Official Databases</h4>
To add the new weather element to just the Fcst and Official databases,
include a line similar to that below after all of the weather element
definitions
(and any <a href="#AddinganewTimeConstraint">new time constraint
definitions</a>).
The line is in the standard <a
href="serverConfig.html#WeatherElementGroupings">parm
grouping format, with the exception that the name of the parm group is
"parm".</a>This format consists of a list of new weather elements and
their
time constraint.&nbsp; The time constraint can be an existing one in
the
serverConfig.py, or a <a href="#AddinganewTimeConstraint">new one
defined</a>
earlier in localConfig.py.&nbsp; <b><font color="#ff0000">Be sure that
the name to the left of the entry is "parms".</font></b>
<p><tt>parms = [([rh], TC1)]</tt>
</p>
<p>If you choose to add multiple parms using the same time constraint,
then the second line needs to be modified to be in this format:
</p>
<p><tt>parms = [([parm1, parm2, parm3], tc1)]</tt>
</p>
<p>If you choose to add multiple parms using different time
constraints,
then the second line needs to be modified to be in this format:
</p>
<p><tt>parms = [([parm1], tc1), ([parm2], tc2), ([parm3, parm4], tc3)]</tt>
</p>
<p><i>Note: There can only be one "parms =" line in the localConfig.py
file.&nbsp; If you use more than one, then only the last one will be
used.</i>
<br>
&nbsp;
</p>
<h4>Adding the New Weather Element to a New Database</h4>
If you only want to add a new weather element for a new database, and
not
the Fcst and Official databases, then do not include your weather
element
in the parms statement.&nbsp; However, if you add it to a new database,
then you will usually want to add it to the Fcst and Official databases
so you can edit it.&nbsp; You will include the list of weather elements
when you <a href="#AddinganewDatabase">define a new database</a>.
<h4>Adding The New Weather Element to a New Database and the
Fcst/Official
Databases</h4>
If you want to add the new weather element to both new databases, and
the
Fcst/Official databases, then include the weather elements in the parms
line, and include it in the list of weather elements when you <a
href="#AddinganewDatabase">define
a new database</a>.
<br>
&nbsp;
<h4>Adding the New Weather Element to one of the standard model
Databases</h4>
You can add new weather elements to one of the standard model
databases.&nbsp;
The syntax is identical to that described above, except that the Python
object name is not "parms", instead it is different depending upon the
model you are modifying.&nbsp; The following table relates the standard
models and the Python object name that is required:

<p>Keep in mind that adding a new element to one of the standard model
databases does not cause that field to be automatically generated by
the
initialization routines.&nbsp; You will have to also write a smart
initialization
algorithm for that database.&nbsp; Refer to the <a
href="SmartInit.html">Smart
Initialization Configuration and User's Guide</a> for more details.
</p>
<p>Here is an example of adding the relative humidity weather element
with
a three-hour time constraint to the NAM12 database:
</p>
<p><tt>rh =&nbsp;&nbsp;&nbsp; ("RH", SCALAR, "%", "Relative Humidity",
100.0, 0.0, 0, NO)</tt>
<br>
<tt>parmsNAM12 = [([rh], TC3)]</tt>

Weather
Element</h1>
This is not supported through localConfig.py.
<br>
<hr width="100%">
<h1><a name="ModifyanexistingWeatherElementsAttributes"></a>Modify an
existing
Weather Element's Attributes</h1>
An existing weather elements attributes can be modified by duplicating
the entry in serverConfig.py, modifying the particular attributes, and
prefixing 'serverConfig.' to the beginning of the definition:
<p><tt>serverConfig.Temp =&nbsp;&nbsp;&nbsp; ("T", SCALAR, "F",
"Surface
Temperature",</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; 120.0,
-30.0, 0, NO)</tt>
</p>
<p>The entry above changes the definition of temperature to range from
-30 to +120 degrees.&nbsp; The minimum possible value was
changed.&nbsp;
This will affect all databases that use the "Temp" weather element.
</p>
<p>You can modify the association between an existing weather element
and
its time constraints (parm groups) through localConfig.py.&nbsp; If you
simply want to change the time constraints associated with an existing

<h1><a name="AddanewProjection"></a>Add a new Projection</h1>
Adding a new projection is straight forward once you figure out all of
the constants that are required.&nbsp; Refer to the <a
href="serverConfig.html#ProjectionConfigurationSection">projection
configuration information in serverConfig.py</a> for more details.
<p>Here is an example of adding a Local211 projection, which is similar
to the Grid211 except that the 'North is up' has been changed from 95
degrees
west longitude to 116 degrees west longitude:
</p>
<p><tt>Local211 = ('Local211', LAMBERT_CONFORMAL,</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (-133.459, 12.190), (-49.385,
57.290),</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (-116.0, 25.0), 25.0, 25.0, (1,
1), (93, 65), 0.0, 0.0, 0.0)</tt>
<br>
&nbsp;
</p>
<p>If you do create your own projection, you should strive to name it
differently
from the standard projections provided with the system.&nbsp; In the
above
example we created a Local211 projection and named it 'Local211' in the
first argument.
</p>
<p>Adding a new projection does no good unless you use it in a new or
modified
site definition.&nbsp; Therefore if you add a new projection for your
site,
you also will want to update the site definition (grid size, location,
and projection) information.
</p>
<p>For example, changing Boise from Grid211 to the Local211 projection
would require the following lines in localConfig.py.
</p>
<p><tt>from serverConfig import *</tt>
<br>
<tt>import serverConfig</tt>
<br>
<tt>Local211 = ('Local211', LAMBERT_CONFORMAL,</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (-133.459, 12.190), (-49.385,
57.290),</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (-116.0, 25.0), 25.0, 25.0, (1,
1), (93, 65), 0.0, 0.0, 0.0)</tt>
<br>
<tt>SITES['BOI'] = ([45, 45], (25.00, 34.00), (11.0, 11.0), 'MST7MDT',
Local211))</tt>
</p>
<p>Note that when changing a projection, you will also be changing the
AWIPS world coordinate systems as defined.&nbsp; This can result in a
distorted
map background.

<h4>Adjusting the Grid Resolution</h4>
The numbers that define the grid resolution are not particularily
obvious.&nbsp;
The grid resolution is determined from the grid location on Earth
(defined
by Grid Origin, Grid Extent, and Projection), and the Grid Size.&nbsp;
The nominal resolution of the common AWIPS projections are shown in the
table below.&nbsp; They are equivilant to a grid box of (1,1) in
size.&nbsp;
The approximate resolution of your domain entry can be figured by:
<p><tt>approx resolution = projectionResolution * (extent / (grid size
- 1))</tt>
</p>
<p>Solving for your grid size results in the following equation; enter
your desired resolution:
</p>
<p><tt>grid size = (projectionResolution * extent / desiredResolution)
+ 1</tt>
</p>
<p>The resulting grid size defines the number of grid cells in each
direction
for the given resolution. For example, if you were on the Grid211
projection
with an AWIPS world coordinate extent of 9.0, and would like a
resolution
of approximately 2.5 kilometers, the approximate grid size you would
use
would be:
</p>
<p><tt>grid size = 80 * 9.0 / 5.0 + 1</tt>
<br>
<tt>grid size = 145</tt>
</p>
<p>Therefore an example entry&nbsp; would change from this:
</p>
<p><tt>SITES['AAA'] = ([145, 145], (23.00, 22.00), (9.0, 9.0),
'MST7MDT',
Grid211, 'wfo')</tt>
</p>
<p>to this:
</p>
<p><tt>SITES['AAA'] = ([289, 289], (23.00, 22.00), (9.0, 9.0),
'MST7MDT',
Grid211, 'wfo')</tt>
</p>
<p>You can get different resolutions in the x and y direction which is
generally not recommended.&nbsp; To avoid this, make sure that the
ratio
of extent and grid size are identical.

<h1><a name="AddinganewTimeConstraint"></a>Adding a new Time Constraint</h1>
Adding a new time constraint is straight forward.&nbsp; It has the same
format as described in the <a
href="serverConfig.html#TimeConstraintConfiguration">time
constraint section of serverConfig.py</a>.&nbsp; You can make use of
the
localTC() script defined in serverConfig.py if desired.
<p>The following line adds a new time constraint with the name of TC8,
that starts at 0200z, repeats every eight hours, and has a duration of
four hours.&nbsp; The second line adds a new time constraint with the
name
of LT9 that starts at 900am local time, repeats every 24 hours, and has
a duration of 3 hours:
</p>
<p><tt>TC8&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; = (2*HOUR, 8*HOUR, 4*HOUR)</tt>
<br>
<tt>LT9 = localTC(9*HOUR, 24*HOUR, 3*HOUR, 0)</tt>
</p>
<p>Simply adding a new time constraint by itself provides no benefit,
unless
you also define new parm groupings and a database.&nbsp; Any new time
constraints
to be used with new weather elements need to be defined before the
definition
is used.

Modifying an existing time constraint is fairly easy.&nbsp; Simply copy

so it starts at 500am local time and runs until 800pm local time
(start=5,
repeat=24, duration=15); the daylight savings flag is set to zero.
<p><tt>serverConfig.MaxTTC&nbsp;&nbsp;&nbsp;&nbsp; = localTC(5*HOUR,

<h1><a name="AddinganewDatabase"></a>Adding a new Database</h1>
There are several steps to adding a new database:
<ul>
<li>First, ask yourself if you really want to do this.&nbsp; There
may be
other
techniques available that if used, will not require the addition of a
new
database.</li>
<li>Define any <a href="#AddinganewWeatherElement">new weather
elements</a>
that you want in this database.</li>
<li>Define any <a href="#AddinganewTimeConstraint">new time
constraints</a>
that will be needed by this database.</li>
<li>Define the <a href="#DefiningDatabaseAttributes">database
attributes</a>
for the new database.</li>
<li>Define the <a href="#DefiningNewParmGroupings">new parm groupings</a>
for
this database.</li>
<li> <a href="#AddingtheDatabasetothelistofnewdatabases">Add the
database to
the list</a> of new databases.</li>
</ul>
<h4>
<a name="DefiningDatabaseAttributes"></a>Defining Database Attributes</h4>
The database attributes for the new database are defined in the same
format
as those in the <a href="serverConfig.html#DatabaseModelConfiguration">serverConfig.py</a>.
<p>If you were adding a new database with the following characterstics:
<br>
&nbsp;
<table nosave="" border="1" width="100%">
<tbody>
<tr>
<td>Model Name</td>
<td>Climo</td>
</tr>
<tr>
<td>Format (always GRID)</td>
<td>GRID</td>
</tr>
<tr>
<td>Optional Type, simply used to filter viewable databases by
the GFE
through <a href="gfeConfig_DB.html#MutableDatabaseandViewableDatabase">gfe
configuration file</a></td>
<td>""</td>
</tr>
<tr>
<td>Singleton</td>
<td>YES</td>
</tr>
<tr>
<td>Official</td>
<td>NO</td>
</tr>
<tr>
<td>Number of Versions&nbsp;</td>
<td>1</td>
</tr>
<tr>
<td>Grid Purge Age</td>
<td>48 hours</td>
</tr>
</tbody>
</table>
</p>
<p>then you would use the following syntax to define this database
attribute:
</p>
<p><tt>Climo&nbsp;&nbsp; = ('Climo',&nbsp;&nbsp; GRID,&nbsp;&nbsp; '',
YES, NO,&nbsp; 1, 48)</tt>
</p>
<p>However, if you are modifying an already defined database, then be
sure
to prefix your entry with serverConfig.&nbsp; For example, to modify
the
NAM12 database to retain 4 versions, the entry in localConfig.py will
be:
</p>
<p><tt>serverConfig.NAM12 = ('NAM12', GRID, '', NO,&nbsp; NO, 4, 0)</tt>
<br>
&nbsp;
</p>
<h4><a name="DefiningNewParmGroupings"></a>Defining New Parm Groupings</h4>
Now you need to define the list of weather elements and their time
constraints.&nbsp;
The list of weather elements can include previous definitions from
serverConfig
and your new definitions. The composite list of weather elements and
time
constraints is done in an identical manner to that described in <a
href="serverConfig.html#WeatherElementGroupings">serverConfig.py</a>.&nbsp;
Of course, you will first need to define any new time constraints that
you plan to use.
<p>In this example, we have assumed to already add the definitions for
the the following weather elements: NormalMax, NormalMin.&nbsp; We plan
to use existing local time definitions for max and min temperature so
we
don't need to redefine or define new ones.
</p>
<p><tt>CLIMO_MODEL = [([NormalMax], MaxTTC), ([NormalMin], MinTTC)]</tt>
</p>
<h4><a name="AddingtheDatabasetothelistofnewdatabases"></a>Adding the
Database

The final step is to relate the parm groupings to the database
attributes
and then append those to a list of new databases.&nbsp; This is done in
the simliar format to&nbsp; <a
href="serverConfig.html#DatabaseGroupings">database
groupings in serverConfig.py</a>.&nbsp; The Python variable that is
expected
is 'localDBs'.
<p><tt>dbs = [(Climo, CLIMO_MODEL)]</tt>
</p>
<p>If multiple local databases were required, the format of the entry
would

<h1><a name="ModifyingExistingParmGroups"></a>Modifying Existing Parm

Modification of existing parm groups through localConfig.py is used to

You can&nbsp; modify existing parm groups for the Fcst and Official
databases,
or any of the standard model databases,&nbsp; through this method.
<p>Modifying an existing parm group is accomplished by linking new or
existing
weather elements to new or existing time constraints.&nbsp; This is
similar
to the technique in <a href="#AddinganewWeatherElement">Adding A New
Weather
Element</a>.
</p>
<p>To modify the existing parm group for the Fcst and Official
databases,
include a line similar to that below after all of the weather element
definitions
(and any <a href="#AddinganewTimeConstraint">new time constraint
definitions</a>).
The line is in the standard <a
href="serverConfig.html#WeatherElementGroupings">parm
grouping format, with the exception that the name of the parm group is
"parm".</a>This format consists of a list of new weather elements and
their
time constraint.&nbsp; The time constraint can be an existing one in
the
serverConfig.py, or a <a href="#AddinganewTimeConstraint">new one
defined</a>
earlier in localConfig.py.&nbsp; <b><font color="#ff0000">Be sure that
the name to the left of the entry is "parms".</font></b>
</p>
<p><tt>parms = [([rh], TC1)]</tt>
</p>
<p>If you choose to add multiple parms using the same time constraint,
then the&nbsp; line needs to be modified to be in this format:
</p>
<p><tt>parms = [([parm1, parm2, parm3], tc1)]</tt>
</p>
<p>&nbsp;If you choose to add multiple parms using different time
constraints,
then the second line needs to be modified to be in this format:
</p>
<p><tt>parms = [([parm1], tc1), ([parm2], tc2), ([parm3, parm4], tc3)]</tt>
</p>
<p>For example, if you want the T, Td, Wind, Wx, and Sky parameters to
all be 3 hours in length, with no gaps, you would use the existing
TC3NG
time constraint.&nbsp; If you wanted the MaxT and MinT parameters to be
18 hours in length instead of 12, then you would need to create two new
time constraints. The lines that would be placed in localConfig.py
would
be:
</p>
<p><tt>MaxTTC18 = localTC(4*HOUR, 24*HOUR, 18*HOUR, 0)</tt>
<br>
<tt>MinTTC18 = localTC(16*HOUR, 24*HOUR, 18*HOUR, 0)</tt>
<br>
<tt>parms = [([T, Td, Wind, Wx, Sky], TC3NG), ([MaxT], MaxTTC18),
([MinT],
MinTTC18)]</tt>
</p>
<p><a href="EXAMPLElocalConfigModParmGroups.py">Example localConfig file</a>
</p>
<p><i>Note: There can only be one "parms =" line in the localConfig.py

</p>
<p>Likewise, you can modify existing parm groupings for the models

use
the correct statement for the model.&nbsp; Refer to the table under <a

for the models.
</p>
<p>For example, if you wanted to modify the RAP40 T (temperature) and

existing databases. You can also choose to skip certain model runs for
each model if desired. Refer to the <a href="SmartInit.html">Smart
Initialization
documentation</a> for more details on smart initialization.&nbsp; The
entry
in serverConfig.py can be completely overridden using the following
syntax (which is not recommended):
<p><tt>serverConfig.INITMODULES = {</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; moduleName : ["d2dmodelname",
"d2dmodelname"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; modulename :
["d2dmodelname"]</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }</tt>
</p>
<p>An example is shown in the following example, where the NAM
initialization
(D2D modelname NAM12) is now going to be controlled by module name
MyNAM.
</p>
<p><tt>serverConfig.INITMODULES = {</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "NAM40" : ["NAM40", "NAM20"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "RAP40" : ["RAP40"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "GFS40" : ["GFS40"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "MyNAM" : ["NAM12"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "gfsLR" : ["gfsLR"]</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; }</tt>
</p>
<p>There are alternate ways of adding an entry, modifying an entry, or
deleting an entry.&nbsp;
The method of completely redefining INITMODULES as shown above is not
recommended.<br>
&nbsp;
</p>
<h2>Adding An Entry</h2>
The format is:
<p><tt>serverConfig.INITMODULES["newModuleName" = ["d2dmodel",
"anotherd2dmodel"]</tt>
</p>
<p>Example of adding a new initialization module for LAPS, which we
assume
that a user has created a LAPS.py and placed it into
<i>/awips2/edex/data/utility/edex_static/site/SITE_ID/smartinit</i>:
</p>
<p><tt>serverConfig.INITMODULES["LAPS] = ["LAPS"]</tt>
</p>
<h2>Modifying An Entry</h2>
Modifying an entry uses the adding and deleting entry syntax.&nbsp;
First
you add the new initialization module, then you delete the old
one.&nbsp;
In this example we are changing the initialization module from NAM12 to
MyNAM
for the NAM12 model:
<p><tt>serverConfig.INITMODULES["MyNAM"] = ["NAM12"]</tt>
<br>
<tt>del serverConfig.INITMODULES["NAM12"]</tt>
</p>
<h2>Deleting An Entry</h2>
The format is:
<p><tt>del serverConfig.INITMODULES[moduleName]</tt>
</p>
<p>Example of deleting the RUC is:
</p>
<p><tt>del serverConfig.INITMODULES["RUC"]</tt>
<br>
&nbsp;
</p>
<h2>Skipping Model Runs</h2>
The user can choose to skip model runs for any of the initialization
modules.&nbsp;
The entry in serverConfig.py can be overriden using the following
syntax:
<p><tt>serverConfig.INITSKIPS = {</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; modelname : [skiptime1,
skiptime2,
skiptime3],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; modelname : [skiptime1,
skiptime2],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; }</tt>
</p>
<p>Note that unlike the INITMODULES, the key in this dictionary is the
modelname, and not the module name. An example is shown in the
following
example, where the RAP40 initialization is skipped except for every 3
hours,
and the NAM40/NAM20 run is skipped for the 00z run:
</p>
<p><tt>serverConfig.INITSKIPS = {</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "NAM40" : [0],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "NAM20" : [0],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "RAP40" :
[1,2,4,5,7,8,10,11,13,14,16,17,19,20,22,23],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; }</tt>
</p>
<p>There are alternate ways of adding an entry, modifying an entry, or
deleting an entry which are similar to that described above in the
INITMODULES
section which should be used.<br>
</p>

<h2><a name="Logs"></a>Modifying the Number of Days to Keep Logs</h2>
You may override the serverConfig.py's definition of the number of days
to keep the GFESuite logs with this syntax:
<p><tt>serverConfig.LOG_FILE_PURGE_AFTER = 6</tt>
<br>
</p>
<p></p>
<hr width="100%">
<h2><a name="ExtraPrecision"></a>Defining Extra Precision for Certain
Weather
Elements</h2>
Weather Elements are stored in their specified precision in GFE,
thus if you have the precision set to 0 for a weather element, it will
effectively be stored as integers.&nbsp; Sometimes you might want
additional
precision available for certain weather elements in order to faciliate
computations on the data.&nbsp; For those cases, where you don't want
to
specify a higher precision (which affects labeling, sampling, ISC data
sizes, etc.), you can use the ExtraWEPrecision entry.&nbsp; The entry
is
a listing of weather elements that require extra precision.&nbsp; The
effective
precision assigned to these elements is one more than that defined in
the
weather element configuration section in serverConfig, if the string
version
of the definition is used, or the precision increase value, if the
tuple
(wename, extraprecision) form is used..&nbsp; To declare an additional
weather element to contain extra precision, use this format:
<p><tt>serverConfig.ExtraWEPrecision.append('parmname')</tt>
</p>
<p><tt>serverConfig.ExtraWEPrecision.append(('parmname', extraPrec))</tt>
</p>
<p>To redefine the entire list, use this format:
</p>
<p><tt>serverConfig.ExtraWEPrecision = ['parmname1', 'parmname2',
'parmname3',
...]</tt>
</p>
<p><tt>serverConfig.ExtraWEPrecision = [('parmname1', exPrec1),
'parmname2',
('parmname3', exPrec3), ...]</tt>
</p>
<p>The forms of 'parmname' and ('parmname', extraPrecAmount) may be
contained
in the same statement.
<br>
</p>
<hr width="100%">
<h2><a name="D2DAccum"></a>Defining D2D Accumulative Weather Elements</h2>
The dictionary of accumulative weather elements is defined by model and
weather element.&nbsp; If a weather element is declared, then the
software
will treat that element as a duration or accumulative element.&nbsp;
The
model grid time will be considered as the ending time of the grid
rather
than a snapshot time.&nbsp; Through localConfig.py, you can modify and
entry, add a new entry, or delete an entry.&nbsp; You may also redefine
the entire dictionary.&nbsp; The element names do not include the level
definition.<br>
<br>
It is recommended that you follow the technique to add, remove, and
modify entries, rather than redefining the entire dictionary.<br>
<p>To add a new model entry:
</p>
<p><tt>serverConfig.D2DAccumulativeElements["modelName"] = ["elem1",
"elem2",
"elem3"]</tt>
</p>
<p>To remove an existing model entry:
</p>
<p><tt>del serverConfig.D2DAccumulativeElements["modelName"]</tt>
</p>
<p>To modify an existing entry:
</p>
<p><tt>serverConfig.D2DAccumulativeElements["modelName"] = ["elem1",
"elem2",
"elem3"]</tt>
</p>
<p>To redefine the entire dictionary:
</p>
<p><tt>serverConfig.D2DAccumulativeElements= {</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "GFS40": ["tp", "cp"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "NAM80": ["tp", "cp"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "RAP40": ["tp", "cp"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "NAM40": ["tp", "cp"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "NAM20": ["tp", "cp"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "MSAS": ["tp", "cp"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "LAPS": ["pc"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "HPCQPF": ["tpHPC"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "HPCdelta": ["pop"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; "NAM12": ["tp", "cp"],</tt>
<br>
<tt>&nbsp;&nbsp;&nbsp; }</tt>

<h2><a name="NotifyTextProd"></a>Automatic Configuration of
NotifyTextProd</h2>
NotifyTextProd is a AWIPS D2D process that routes certain text
bulletins to the VTECDecoder. The pattern file is automatically created when GFE
is loaded in EDEX and is customized to the configured site. This
reduces the amount of traffic being sent to the VTECDecoder by 90%.<br>
<br>
Due to the staging of the GFESuite and AWIPS softwares, a configuration
item is required to tell GFE to begin generating the custom
pattern file. This is done through a simple localConfig.py
addition:<br>
<br>
<span style="font-weight: bold; font-family: monospace;">serverConfig.AUTO_CONFIGURE_NOTIFYTEXTPROD
= 1</span><br>
<br>
<hr style="width: 100%; height: 2px;">
<h2><span style="font-weight: bold;"><a name="ISC"></a></span>Intersite
Coordination Grids Configuration
</h2>
The Intersite Coordination Grids configuration can be overridden in the
localConfig.py file.&nbsp; <br>
<h3>ISC Routing Table Address</h3>
The base url for the ISC Routing Table web server may be changed from
the default.&nbsp; This is normally only done for isolated
testing.&nbsp; The baseline value of this entry is sufficient.&nbsp;
The value of None indicates no ISC Routing Web Service, which precludes
the transmission and reception of ISC data. To modify the default
value, use this syntax:<br>
<br>
<span style="font-family: monospace;">serverConfig.ISC_ROUTING_TABLE_ADDRESS
= "http://exampleurl.nws.noaa.gov"</span><br>
<h3>Requested ISC Sites</h3>
The default is to have EDEX calculate the list of sites to
request ISC data from based on the generated ISC_xxx edit
areas.&nbsp;&nbsp; This is accomplished by setting the value to None.
If you wish to override this value, then use this syntax:<br>
<br>
<span style="font-family: monospace;">serverConfig.REQUESTED_ISC_SITES
= ["CLE", "PBZ", "CTP", "BUF"]</span><br>
<br>
Be sure to always include your own site; if you don't you won't see
your own ISC data in the ISC database.<br>
<br>
<h3>Request ISC</h3>
Setting the value to 0 disables the request of ISC data and
EDEX will not register with the ISC Routing Table Web
Server. To enable the reception of ISC data, you use this
syntax in the localConfig.py file:<br>
<br>
<span style="font-family: monospace;">serverConfig.REQUEST_ISC = 1</span><br>
<br>
<h3>Send ISC On Save</h3>
Setting the value to 0 disables sending of ISC data when data is saved
to the Fcst database.&nbsp; Setting the value to 1 will send ISC data
when data is stored to the Fcst database.<br>
<br>
<span style="font-family: monospace;">serverConfig.SEND_ISC_ON_SAVE = 1</span><br>
<br>
<h3>Send ISC On Publish</h3>
Setting the value to 0 disables sending of ISC data when data is
published
to the Fcst database.&nbsp; Setting the value to 1 will send ISC data
when
data is stored to the publish database.<br>
<br>
<span style="font-family: monospace;">serverConfig.SEND_ISC_ON_PUBLISH
= 1</span><br>
<br>
<h3>Requested ISC Parms</h3>
The default is to have EDEX calculate the list of weather
elements to be requested from the list of available weather elements in
the Fcst database. This is denoted by setting the variable to None.
&nbsp; The site can override this and specify a list of weather
elements desired from ISC as a list. If you wish to override
this value, then use this syntax:<br>
<br>
<span style="font-family: monospace;">serverConfig.REQUESTED_ISC_PARMS
= ["T_SFC", "Td_SFC", "Wx", "Wind"]</span><br>
<br>
You can just specify the weather element name (e.g., T), or the weather
element name and the level (e.g., T_SFC, T_MB700).<br>
<br>
<h3>Transmit Script</h3>
The transmit script is used to move the data from the server machine to
the destination.&nbsp; For AWIPS, this is the msg_send
program.&nbsp;&nbsp; For testing or other purposes, you can override
the entry and specify your own program.&nbsp;&nbsp; The program you
specify should expect the following switches:<br>
<ul>
<li>-s - subject line, normally ISCGRIDS</li>
<li>-a - address list, generates comma separated addressee list, such
as "CLE,PBZ,BUF"<br>
</li>
<li>-i - id string, normally similar to TTAA0 KXXX 021232</li>
<li>-c - AWIPS MHS code, normally 11</li>
<li>-p - priority mode, 0 is lowest, 2 is highest</li>
<li>-e - enclosure list, such as "f1, f2, f3", containing the ISC
data compressed, and the ISC destination routing information </li>
</ul>
Use this syntax to specify a different program:<br>
<br>
<span style="font-family: monospace;">serverConfig.TRANSMIT_SCRIPT =
"/awips/bin/msg_send"<br>
<br>
</span>
<h3>Extra ISC Weather Elements<br>
</h3>
The Extra ISC Weather Elements allows you to configure your ISC
database to store weather elements received from a different office
type, such as receiving rfc grids at a wfo.&nbsp; You never need to add
an entry for your own "office type", just others.&nbsp; Use this syntax
to specify the set of weather elements and office types:<br>
<br>
To completely replace the serverConfig definition:<br>
<br>
<span style="font-family: monospace;">serverConfig.EXTRA_ISC_PARMS =
[([T,Wind], 'rfc')]<br>
<br>
</span>To augment the serverConfig definition:<span
style="font-family: monospace;"><br>
<br>
extraISCparms = [([RH, QPF], 'rfc')]<br>
