MPAS ocean and ice models currently have their own (non-CESM'ish) naming convention for monthly output files. ncclimo recognizes input files as being MPAS-style when invoked with "-c hist" and "-m ocnm mpaso" or "-m icempascice". Use the optional "-f fml_nm" switch to replace "hist" with a more descriptive simulation name for the output. Invocation looks like this:

ncclimo -cm mpaso hist -m ocn -s 1980 -e 1983 -i drc_in -o drc_out # MPAS-O

ncclimo -c hist -m icempascice -s 1980 -e 1983 -i drc_in -o drc_out # MPAS-I

...

ncclimo -p mpi -c ${caseid} -m cam      -s 2 -e 5 -i $drc_in -r $map_atm -o ${DATA}/acme/atm
ncclimo        -c ${caseid} -m clm2     -s 2 -e 5 -i $drc_in -r $map_lnd -o ${DATA}/acme/lnd
ncclimo -p mpi -c hist              -m ocnmpaso    -s 2 -e 5 -i $drc_in -r $map_ocn -o ${DATA}/acme/ocn 
ncclimo         -c hist            -m icempascice  -s 2 -e 5 -i $drc_in -r $map_ice -o ${DATA}/acme/ice

The atmosphere and ocean model output is significantly larger than the land and ice model output. These commands recognize that by using different parallelization strategies that may (rhea standard queue) or may not (cooley or rhea bigmem queue) be required, depending on the fatness of the analysis nodes, as explained below. As of late 2016 (and NCO v. 4.6.3-alpha03), the MPAS models do not utilize the $caseid option. They use their own, evolving MPAS naming convention. When fed the '-m' options shown above, ncclimo processes the MPAS "hist.am.timeSeriesStatsMonthly" analysis members.

Extended climos:

ncclimo can re-use previous work and produce extended (i.e., longer duration) climatologies by combining two previously computed climatologies (this is called the binary method, and was introduced in NCO 4.6.3-alpha02) or by computing a new climatology from raw monthly model output and then combining that with a previously computed climatology (this is called the incremental method, and was introduced in NCO 4.6.2). Producing an extended climatology by the incremental method requires specifying (with -S and -s, respectively) the start years of the previously computed and current climo and (with -e) the end year of the current climo. Producing an extended climatology by the binary method requires specifying both the start years (with -S and -s) and end years (with -E and -e) of both pre-computed climatologies. The presence of the -E option signifies to ncclimo to employ the binary (not incremental) method.
