|
||
|
|
<p>Here is a listing of various techniques and skills which you need to
|
||
|
|
develop in order to gain the most utility from the gridded forecast editor
|
||
|
|
software package. This list is arranged by subject, but using the GFE software
|
||
|
|
requires thorough knowledge of a wide variety of operations. Through repetition,
|
||
|
|
executing each of these skills and techniques should become second nature,
|
||
|
|
like calling up a satellite picture on D2D.
|
||
|
|
<p>This document is intended for forecasters who have been thoroughly trained
|
||
|
|
on the operational use of the GFE; it it not for the novice. Each
|
||
|
|
forecaster should be able to demonstrate a mastery of each of these skills
|
||
|
|
before attempting to use the GFE for complete operational forecasts.
