If/when MPAS O/I generates the _FillValue attributes itself, this step can and should be skipped. All other climo_nco.sh features like regridding (below) are invoked identically for MPAS as for CAM/CLM users although under-the-hood climo_nco.sh does do some special pre-processing (dimension permutation, metadata annotation) for MPAS. A five-year oEC60to30 MPAS-O climo with regridding to T62 takes < 10 minutes on rhea.
Regridding
...
(climos and other files):
climo_nco.sh will (optionally) regrid during climatology generation and produce climatology files on both the native and desired analysis grids. This regridding is virtually free, because it is performed on idle nodes/cores after the monthly climatologies have been computed and while the seasonal climatologies are being computed. This load-balancing can save half an hour on ne120 datasets. To regrid, simply pass the desired mapfile name with "-r map.nc", e.g., "-r ${DATA}/maps/map_ne120np4_to_fv257x512_aave.20150901.nc". Although this should not be necessary for normal use, you may pass any options specific to regridding with "-R opt1 opt2".
