Hi John, all, I also reported the same issue few weeks ago, but without any answer: http://www.unidata.ucar.edu/mailing_lists/archives/thredds/2010/msg00346.html ; urls provided in that link don't work yet, and updated datasets can be found here: http://mandeo.meteogalicia.es/thredds/catalogos/SWAN/swan_catalog.html but the problem is still the same. We also developed a tool that allows users request data through NCSS (as point dataset) by clicking on a map and there you can see a bit of the problem: http://sor.meteogalicia.es:8080/mg-web-raia/visor/raia/html/visorRAIA.html?request_locale=en In the SWAN layers, which have two-dimensional lat/lon, sometimes you don't get any data because of the server error you mentioned and when you get data the lat/lon in the NCSS response showed in the popup doesn't match with the lat/lon on the map. And regarding netCDFSubset I'm also wondering if there is some underway solution to the problem with multiple variables with different vertical coordinates in requests as point dataset. Cheers!
