Hi Matthias:

The CDM/TDS does not support Compression by Gathering, nor does any other package i know of. There was some internal talk in CF of deprecating this. I am cc'ing the CF list in case anyone there wants to comment.

Have you looked at using netcdf-4 with compression?

Dear Thredds experts,

in order to save us some disk space and maybe increase the performance of a Thredds/ncWMS server we are planning to apply "Compression by Gathering" (CF Conventions 1.6, section 8.2) to our landuse and land-bound climate datasets. Before adapting our data massaging routines I would like to make sure that the results will be compatible with the Thredds server.

Can you please comfirm that Thredds supports netCDF files that utilize "Compression by Gathering"?

Thank you,
Matthias
