The netCDF Operators NCO version 4.9.5 have snuck in.

http://nco.sf.net (Homepage, Mailing lists, Help)
http://github.com/nco (Source Code, Issues, Releases, Developers)

What's new?
Version 4.9.5 is a minor NCO release that contains a few new features
and fixes to more smoothly work with current and future releases of
the E3SM climate model and with the next netCDF release. Unless the
features/fixes listed below affect you, chillax and upgrade next
time.

Work on NCO 4.9.6 has commenced and will improve high-freqency
splitting and climo capabilities, more SIMD acceleration, and
more GPU offloading support.

Enjoy,
Charlie

NEW FEATURE (full details always in ChangeLog):

A. ncclimo supports alternates to "area" and "ncol" as names
for the area field and the horizontal dimension that it assumes
for computing global average means from splitter output with
the --glb_avg option, and for creating CMIP6-like timeseries that
automatically include the area variable.
Two new options, --area_nm and --hrz_dmn, control the name
of the area variable (default is "area") and of the horizontal
dimension(s) (default="ncol") over which to average the
splitter output when invoked with --glb_avg.
For alternate names invoke with, e.g.,

ncclimo --glb_avg --area=area_p ...
ncclimo --glb_avg --area=area_d --hrz_dmn=ncol_d ...
ncclimo --glb_avg --hrz_dmn=lat,lon ...

In all cases the splitter will output the correct area variable.

BUG FIXES:

A. The prototype for the nco_def_var_filterx() function
has been changed to agree with the next netCDF release.

B. An OpenMP incompatibility with the Intel Compiler Suite
has been fixed. NCO once again builds fine with Intel.

C. ncatted will now print the full list of parameters recorded
in a (netCDF4) variable's _Filter attribute.

D. Fix a bug in the computation of the intersection mesh
between two RLL grids that crept into the 4.9.4 release.
