[gradsusr] Average wind and swell values NOAA wavewatch III full dataset.

[kent balas]

Hi Gradusers,

I'm new to Grads and am not a computer scientist or Meteorologist (a lowly
Geologist) so pardon my ignorance.  I'd like to use the NOAA wavewatch III
dataset (ftp://polar.ncep.noaa.gov/pub/history/waves/) in *.grb2 format and
grads to get average wind and swell amplitude and direction for any part of
the globe.  I'm fairly sure this is possible as the wavewatch III product
viewer (http://polar.ncep.noaa.gov/waves/viewer.shtml?) does it over the
past 180 hours.  I'd like to get the average values over the full dataset
(1999 - present) and produce an animation of this if possible.  Can someone
help me with where to start?  I'm aware I'll probably need g2ctl, however
my programming knowledge is limited to some basic python so I'm having
trouble with getting started.  Apologies for the basic question.

Kind Regards,

Kent Balas
