We can write a Netcdf file from an OpenDAP dataset that uses the Netcdf-3 data model. Subsetting it by lat/lon bounding box requires that we understand the coordinate system of the dataset, etc. We can do this for a remote URL as with the WCS.
Note that none of this is currently available through the TDS, but we can add this to our to-do list.
The remote data set serving capability of the THREDDS WCS is fantastic, and it would be great if this capability could eventually be added to the NetCDF Server.
(right now, I understand from
that the NetCDF Server currently only works on IDD/NCEP grib data served by the TDS)
Then folks would have a simple tool to extract collections of subsetted variables from any OpenDAP served CDM and receive a NetCDF file. That seems to be what most our users want to do.
