Hi Herbert,
It turns out that a Zstandard filter is already available for HDF5 (which
NetCDF-4 is built upon [1]). However, I don't think the libnetcdf tools (such
as nccopy) can use compression other than zlib, even if the underlying libhdf
has other filters installed. You might want to ask NetCDF support about that:
address@hidden
As for HTTP compression, THREDDS just uses standard gzip, which is actually a
feature of Tomcat, the servlet container. Zstandard doesn't look to be
supported by major web servers or browsers yet.
Cheers,
Christian
