Hi Roy,

With the RSI IDL wcs add on, I've tried 4 of your "aggregated" datasets and all of them returned a geoTIFF without an error message. A couple returned geoTIFFfloat, but a couple others time out. I am unable to access any of the coverages in netCDF form via IDL WCS client. All such attempts return an error message of one sort or another. I haven't done this very systematically yet, so I haven't kept track of the error messages, etc.

Are any of these more "important" than others or easier to visualize and interpret? I have no way to evaluate whether the coverages that do come across make any sense. A handful of "use cases" and expected displays would help in the checkout process.

As to where to publish your WCS server, I need to give that a bit more thought. I was attempting to shift from the GALEON wiki which worked pretty well last year to the GALEON OGCnetwork this year. But I'm not sure the OGCnetwork approach works well for community contributions.

  <http://www.ogcnetwork.net/galeon>http://www.ogcnetwork.net/galeon

Maybe some of the others have suggestions for how to use the OGCnetwork in this fashion.
