I imagine I&#39;d specify the lat long covering the area of interest?  What I want to do is identical to the NOAA product viewer (<a href="http://polar.ncep.noaa.gov/waves/viewer.shtml">http://polar.ncep.noaa.gov/waves/viewer.shtml</a>?) but over 10 years, instead of 180 hrs.  Perhaps animating with a daily or weekly average values.<br>

    You want to get/plot a variable along an arbitrary coastline?  This
    is not going to be straightforward; the output is on a regular
    lat/lon grid.<br>

                                    <div>Hi Gradusers,<br>
                                      <br>
                                      I&#39;m new to Grads and am not a
                                      computer scientist or
                                      Meteorologist (a lowly Geologist)
                                      so pardon my ignorance.  I&#39;d like
                                      to use the NOAA wavewatch III
                                      dataset (<a href="ftp://polar.ncep.noaa.gov/pub/history/waves/" target="_blank">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&#39;m fairly sure this is
                                      possible as the wavewatch III
                                      product viewer (<a href="http://polar.ncep.noaa.gov/waves/viewer.shtml" target="_blank">http://polar.ncep.noaa.gov/waves/viewer.shtml</a>?)


                                      does it over the past 180 hours. 
                                      I&#39;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&#39;m
                                      aware I&#39;ll probably need g2ctl,
                                      however my programming knowledge
                                      is limited to some basic python so
                                      I&#39;m having trouble with getting
                                      started.  Apologies for the basic
                                      question.<br>
                                      <br>
                                      Kind Regards,<br>
