netCDF Operators NCO version 5.1.3 erupt

What's new?
Version 5.1.3 improves the speed of vertical interpolation for
fields whose most-rapidly-varying dimension is the vertical (not
horizontal). This dramatically improves interpolation speed for
EAMxx/SCREAM files. This release also fixes and issue in using
ncremap to invoke the interpolation. Other than that, this release can
be skipped.
Work on NCO 5.1.4 has commenced and aims to add support for Zarr S3
stores and to polish support for new codecs.
Enjoy,
Charlie
NEW FEATURES (full details always in ChangeLog):
A. ncremap can now vertically interpolate files/fields whose most
rapidly varying dimension is the vertical without having to first
permute the dimensions to be most rapidly varying in the horizontal
dimension(s). This speeds up vertical interpolation of EAMxx/SCREAM
fields dramatically (a factor of about three).
ncremap --vrt_out=vrt.nc in.nc out.nc
ncremap -P eamxx --vrt_out=vrt.nc in.nc out.nc

BUG FIXES:
A. ncremap in version 5.1.2 (but not 5.1.1 or earlier) by default
does the wrong thing when trying to vertically interpolate raw
EAMxx/SCREAM files. The workaround is to manually permute the
data vary most rapidly in the horizontal dimension. The fix is to
upgrade.
