Hi Gradusers,<br><br>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 (<a href="ftp://polar.ncep.noaa.gov/pub/history/waves/">ftp://polar.ncep.noaa.gov/pub/history/waves/</a>) 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 (<a href="http://polar.ncep.noaa.gov/waves/viewer.shtml">http://polar.ncep.noaa.gov/waves/viewer.shtml</a>?) 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.<br>
<br>Kind Regards,<br><br>Kent Balas<br>
