<!-- The following XML script generates two animated images each from the latest NCEP GFS forecast and the MIT model.
Improvements to the script are needed and are noted throughout the comments. To run this script, you must save it with the .isl extension
and run the script with the command: runIDV YourScript.isl   -->




<!-- Loads Theta/Speed Iso data from latest NCEP GFS Global 1 degree (make sure to set "times" correctly)
For example, 0:28:4 means to load only from frame 0 to frame 28 at intervals of 4. -->

<!-- Now we create displays from GFS forecast. We cannot create a custom display (e.g. specifying isosurface value)
for the isosurface because GFS contains data for the entire Earth. There is no script that allows an
isosurface to be created strictly over the Northern Hemisphere. -->
