Subject: Re: [thredds] Compression by Gathering working with Thredds?
Thank you very much for the feedback - this has saved me quite some work. Have
you got soem suggestions which linux distributions are featuring netCDF4 out of
the box? Last time I checked, Suse and Debian were shipped with netCDF3 support
only. Are there any 3rd party repositories that I can include to get
netcdf4-support?
Thanks,
Matthias
