[gradsusr] Problem creating Meteograms for specific locations in Malawi

[Ryan Hickman]

It looks like the GrADS Script (meteogram_gfs.gs) that you are using
contains incorrect base URLs for seeking on the GrADS server.

You could modify the GrADS Script to point to the correct Base URL, or use
the scripts created by Jennifer Adams (COLA) at
ftp://cola.gmu.edu/pub/jma/meteograms/. These scripts were updated
recently, support the GFS 0.25º and appear to have the correct base URLs to
retrieve the GFS datasets.

NOMADS Base URL: http://nomads.ncep.noaa.gov:9090/dods/gfs_0p25
Monsoon Data Base URL: http://monsoondata.org:9090/dods/gfs0p25

You can always view the available datasets on the server by removing
"gfs_0p25 / "gfs0p25" from the URL and visiting it in your browser to get a
listing.
