Re: [thredds] NetCDF Subset Service Reference

Hi Jerry:

You are using an old version of the server (note the URLs start with 
/thredds/ncServer") which only
worked for grib files.

Use the new service as documented in

"http://www.unidata.ucar.edu/projects/THREDDS/tech/reference/NetcdfSubsetService.html";

You will see that the URLs start with "/thredds/ncss/grid"
