<p class="MsoNormal">Hi there,<o:p></o:p></p>
<p class="MsoNormal"><o:p>&nbsp;</o:p></p>
<p class="MsoNormal">I am trying to access aggregated ww3 swell wave data in a remote netcdf file on a THREDDS server.<o:p></o:p></p>
<p class="MsoNormal"><o:p>&nbsp;</o:p></p>
<p class="MsoNormal">When I access the whole dataset via &#8216;sdfopen <a href="http://...ww3_run">
<span style="color:windowtext;text-decoration:none">http://...ww3_run</span></a>&#8217; GrADS does not display the aggregated swell field with &#8220;ordered_sequence_of_data&#8221; as one of the coordinates. Only the fields with level &#8220;Ground or water surface&#8221; are displayed.
 I believe this is level 1 in the original GRIB file. The aggregated swell field is on GRIB level 241.<o:p></o:p></p>
<p class="MsoNormal"><o:p>&nbsp;</o:p></p>
<p class="MsoNormal">Now, I can access individual fields via &#8216;sdfopen <a href="http://...ww3_run?sig_height,time,lat,lon">
http://...ww3_run?sig_height,time,lat,lon</a>&#8217; notation but I still can&#8217;t access the aggregated swell field. I have tried: &#8216;sdfopen
<a href="http://...ww3_run?swell,time,%20ordered_sequence_of_data,lat,lon">http://...ww3_run?swell,time, ordered_sequence_of_data,lat,lon</a>&#8217; but GrADS always returns &#8220;SDF file does not have any non-coordinate variables&#8221;. Other combinations do not work either.<o:p></o:p></p>
<p class="MsoNormal"><o:p>&nbsp;</o:p></p>
<p class="MsoNormal">Can anyone offer any advice/help?<o:p></o:p></p>
<p class="MsoNormal"><o:p>&nbsp;</o:p></p>
<p class="MsoNormal">Kind regards<o:p></o:p></p>
