Hi All, I'm having an issue opening the file at http://data.nodc.noaa.gov/opendap/ghrsst/L4/GLOB/JPL_OUROCEAN/G1SST/2010/160/20100609-JPL_OUROCEAN-L4UHfnd-GLOB-v01-fv01_0-G1SST.nc.bz2' I get very a very different CDL when I open it locally vs when I open it via OPeNDAP (it's served by Hyrax). Most notably the variable attributes for lat, lon and time are 'transmorgified' into global attributes when read via OPeNDAP. Below are the different CDL's. If any knows of a workaround or has insight into what's going I'd appreciate hearing about it. Thanks When I open it with netcdf-java I get the following CDL: ===== WHAT I GET ===== netcdf dods://data.nodc.noaa.gov/opendap/ghrsst/L4/GLOB/JPL_OUROCEAN/G1SST/2010/160/20100609-JPL_OUROCEAN-L4UHfnd-GLOB-v01-fv01_0-G1SST.nc.bz2 { dimensions: time = 1;
