the valid time of any grid block.</font></font>
|
|
<p><font color="#000000">The Grid Manager has a built-in tool for stretching
|
|
the time over which a grid is valid. Move the cursor to the grid
|
|
block that you want to stretch. Press and hold MB2 while moving the
|
|
cursor to the left or right. Stretching the grid block to the left
|
|
changes the grid's start time while stretching the grid block to the right
|
|
changes that grid's end time. Note that you can only stretch the
|
|
start time or the end time per operation. To stretch both times,
|
|
you must perform this operation twice. See the section <a href="GFETrainingGridMgr.html#Stretchagridsvalidtimeperiod">Stretch
|
|
a grid's valid time period</a> in GFE Training Guide for more information.</font>

|
contents of one grid block into another grid block.</font></font>
|
|
<p><font color="#000000">This task is accomplished using the MB3 pop-up
|
|
menu from inside the Grid Manager. Move the cursor over the grid
|
|
block that you wish to copy from. Press and hold MB3 and select "</font><font color="#FF0000">Copy
|
|
Grid</font><font color="#000000">" from the pop-up menu. Next, move
|
|
your cursor to the time at which you want to paste this grid. Press
|
|
and hold MB3 again, but this time select "</font><font color="#FF0000">Paste
|
|
Grid</font><font color="#000000">". Note that you can paste the grid
|
|
into a gap or onto an existing grid. Just the grid data values are
|
|
changed when pasting a grid. The valid time is not affected.

a time range and list of parameters, then copy data from a selected model

into the FCST database.</font></font>
|
|
<p><font color="#000000">This is a two-part task. First you must
|
|
select the time range, then copy grids from a model. To select the
|
|
time range, move the cursor to the start time of the selection and
|
|
over the first weather element you want to select. Press and hold
|
|
MB1 and drag diagonally. Motion in the horizontal direction selects
|
|
the time range. Motion in the vertical direction selects weather
|
|
element. When you have selected the time range and the set of weather
|
|
elements you want, release MB1. For more information on selecting
|
|
weather elements and time ranges in this way, see the GFE Training Guide
|
|
section <a href="GFETrainingGridMgr.html#SelectWEandTimeRange">Select Weather
|
|
Element and TimeRange</a>.</font>
|
|
<p><font color="#000000">Next, you need to identify the model source to
|
|
copy in to your selected Weather Element/TimeRange. Go to the main
|
|
menu and select </font><font color="#FF0000">Populate->Copy Selected Grids
|
|
From...</font><font color="#000000"> A dialog that contains all model
|
|
versions that are curently available will appear. Select the model
|
|
of your choice and select </font><font color="#FF0000">OK</font><font color="#000000">.
|
|
Grids generated from that model will be copied into your forecast.

|
from scratch, move your cursor over the weather element/timerange you wish,
|
|
press and hold MB3 to display the pop-up menu, and select "</font><font color="#FF0000">Create

<p><font color="#000000">Finally, to split the grid block, select a portion
|
|
of it using the instructions Select a time range... Then MB3 press
|
|
to display the pop up menu and select "Spilt Grid". You will end
|
|
up with two grids whose time boundaries are defined by whatever time range
|

you selected.</font>

<p><a NAME="AssignNullValue"></a><font color="#3333FF"><font size=+2>Assign

value) just move your cursor over your grid of choice and MB3 press

to display the pop-up menu. Select "</font><font color="#FF0000">Assign
|
|
[value]</font><font color="#000000">" where [value] is the null value defined
