Hi Matt,
You can find info on using the C API to access different compression filters
here:
* https://www.unidata.ucar.edu/software/netcdf/docs
There is an entry on the left-hand side titled 'Filter Support in netCDF-4
(Enhanced)'. I would provide the direct link but it may change in the next
hour or so, as I push out the next version of netCDF-C. The Fortran interface
will follow; I would expect that release this week, except for the US
Thanksgiving holiday, so next week at the latest.
