With NCO you can manipulate and analyse netCDF and similar files.  It is
a useful addition to to tools that are already there.

So you could do this:

  wget https://cluster.klima.uni-bremen.de/~fmaussion/teaching/climate/CERES_EBAF-Surface_Ed4.1_Clim-2005-2015.nc
  ncdump -h CERES_EBAF-Surface_Ed4.1_Clim-2005-2015.nc | head
  ncrename -d month,mo CERES_EBAF-Surface_Ed4.1_Clim-2005-2015.nc
  ncdump -h CERES_EBAF-Surface_Ed4.1_Clim-2005-2015.nc | head

to rename the time axis.

Apropos, geo/cdo has some of the same functionality, but it is designed
to handle data variables, not meta information like axes names, so
geoscientists will quickly be looking for something like NCO.

OK to add this?
