if you are going to AGU, you may also want to stop by the Larry Knox's (HDF)
e-Lightning talk on compression:
• IN21B-22: Tuning HDF5 (and NetCDF-4) Applications to Overcome and Avoid
Compression Pitfalls
https://agu.confex.com/agu/fm18/meetingapp.cgi/Paper/467672
Unfortunately, the talk part is at 8:10 Tuesday morning, but I think the
e-Lightning poster sticks around (eLightning Theater II) until 10:00 if you
want to come by and talk compression.

All,
This is a bit of a general question inspired by going to the "Compression for
Scientific Data" tutorial at SC18 last week. Namely, is there currently an easy
way to test out and try new compressors like zfp and SZ in netCDF?
I know they need to be compiled and registered and all with HDF5 (which I could
probably get to happen), but as my shop is a netCDF (Fortran) shop and not an
HDF5 shop, I can't quite use them until they can be accessed through netCDF.
A search online shows that perhaps once there was a "compress" branch of
netCDF-C, but it seems stale.
Is there any effort in Unidata to start supporting the HDF5 extra compressors?
Or are they supported and I just don't know enough advanced netCDF to know how
to use them (always possible!)?
Thanks,
Matt
