|
|
<p><a NAME="RunSmartTool"></a><font color="#3333FF"><font size=+2>Run a
|
|
Smart Tool for just the area covered by your WFO.</font></font>
|
|
<p><font color="#330000">Running a Smart tool is just like running any
|
|
of the other simple tools. Select a grid to edit by MB1 clicking
|
|
on that grid in the Grid Manager or MB2 clicking on the label for that
|
|
grid in the Spatial Editor. Next you will need to select the edit
|
|
area that corresponds to your WFO. From the GFE Main Menu, select
|
|
</font><font color="#FF0000">Edit
|
|
Areas->WFOs->[Your site ID]</font><font color="#330000">. Open the <a href="ButtonBarDialogs.html#EditActionsDialog">Edit
|
|
Actions Dialog</a>, if not already, and select the smart tool that you
|
|
wish to run. That tool will be executed over your WFO and presumably
|
|
modify the data for the grid that you choose earlier.</font>
|
|
<p><a NAME="AdjustQPFWithSmartTool"></a><font color="#3333FF"><font size=+2>Adjust
|
|
a QPF grid using the QPF Smart Tool.</font></font>
|
|
<p><font color="#330000">Select a QPF grid to edit using the Grid Manager
|
|
or the legends in the Spatial Editor. Then open the <a href="ButtonBarDialogs.html#EditActionsDialog">Edit
|
|
Actions Dialog</a> and select QPF_SmartTool. If there is any complex
|
|
terrain in your WFO area, you should see a terrain influence in the QPF
|
|
field based on the topography and the wind grid valid at the same time.</font>
|
|
<p><a NAME="MakeMaxTemp"></a><font color="#3333FF"><font size=+2>Interpolate
|
|
temperatures to hourly grids and derive a MaxTemp grid from these grids
|
|
using the Smart Tool.</font></font>
|
|
<p><font color="#330000">To interpolate your temperature grids to hourly,
|
|
first select those grids in the Grid Mangaer using MB1 drag operation.
|
|
See the section Select Weather Element and TimeRange for more information.
|
|
Next, from the Main Menu item select </font><font color="#FF0000">Grids->Interpolate...</font><font color="#330000">.
|
|
The <a href="MainMenuDialogs.html#InterpolateDialog">Interpolate Dialog</a>
|
|
will be displayed, choose "By Gaps". You should see new grid appear in
|
|
between the grids that were already defined. See the section on
|
|
<a href="GFETrainingGridMgr.html#InterpolateGrids">Interpolate
|
|
Grids</a> for more infomation. When the interpolation is finished,
|
|
select a MaxT (max temperature) grid to edit from the Grid Manager that
|
|
corresponds to the same time as the time period that you interpolated.
|
|
Then from the <a href="ButtonBarDialogs.html#EditActionsDialog">Edit Actions
|
|
Dialog</a> select the Smart tool, select </font><font color="#FF0000">MaxT_SmartTool</font><font color="#330000">.
|
|
You should see the values for the MaxT assign the maximum value of the
|
|
temperature grids in that same time range.</font>
|
|
<p><a NAME="DeriveSnowAmtGrid"></a><font color="#3333FF"><font size=+2>Derive
|
|
a SnowAmt grid from the QPF field using the appropriate Smart Tool</font></font>
|
|
<p><font color="#330000">First you will need to define a QPF field either
|
|
by hand or from any model you choose. Next create a SnowAmt grid
|
|
from scratch in the Grid Manager by moving the cursor to the same time
|
|
period in the SnowAmt element, MB3 press and hold to get the pop-up menu
|
|
and select <a href="GFETrainingGridMgr.html#CreateGridfromScratch">Create
|
|
From Scratch</a>. See the section <a href="GFETrainingGridMgr.html#CreateGridfromScratch">Create
|
|
Grid From Scratch</a> for more information. Now open the <a href="ButtonBarDialogs.html#EditActionsDialog">Edit
|
|
Actions Dialog</a> and select </font><font color="#FF0000">SnowAmt_SmartTool</font><font color="#330000">.
|
|
You should see the newly created SnowAmt grid defined with new values.
|
|
Note: this tool requires that a Temperature and Freezing Level grid also
|
|
be defined for the same time period. Also note that if your temperature
|
|
grid is not at or below freezing the SnowAmt_SmartTool will (appropriately)
|
|
assign zero SnowAmt to all grid points.</font>
|
|
<p><a NAME="RunSmartToolOnMultipleGrids"></a><font color="#3333FF"><font size=+2>Run
|
|
a Smart Tool on multiple grids, but only over a selected Edit Area</font></font>
|
|
<p><font color="#330000">To accomplish this task you will need to select
|
|
a time period in the Grid Manager and then select and edit area from the
|
|
Spatial Editor. These can be done in either order. To select
|
|
a time period in the Grid Manager see the section <a href="GFETrainingGridMgr.html#SelectWEandTimeRange">Select
|
|
Weather Element and Time Range</a>. To select an edit area in the
|
|
Spatial Editor see the section <a href="GFETrainingSpatialEditor.html#DefineEditAreabyHand">Select
|
|
an Edit Area by Hand</a>. Once you have defined an edit area and
|
|
a time range, select one of the tools in the <a href="ButtonBarDialogs.html#EditActionsDialog">Edit
|
|
Actions Dialog</a>. Note that all of the grids that you selected
|
|
in the Grid Manager turn a </font><font color="#66FFFF">cyan</font><font color="#330000">
|
|
color while they are executing. When the </font><font color="#66FFFF">cyan</font><font color="#330000">
|
|
color turns back to gray, examine the grids and convince yourself that
|
|
the Smart tool was executed over the edit area that you chose and for each
|
|
of the grids that you selected.</font>
