Notes for building everything MPAS from this tutorial.

Start:

0) Activate env & go to your run dir conda activate mpas_toolchain cd /net/flood/data2/users/x_yan/mpas/MPAS-Model

1) Sanity env (same as before) ulimit -s unlimited export OMP_NUM_THREADS=1

2) Check inputs exist where streams/namelist point ls -l x1.40962.static.nc # or x1.40962.grid.nc, whichever you chose ls -l met/CFSR:2010-10-23_00 # your met file for start_time

(if you changed the prefix/dir/time, adjust accordingly)

3) (Optional) clean previous outputs/logs rm -f x1.40962.init.nc x1.40962.ugwp_oro_data.nc x1.40962.sfc_update.nc lbc..nc
log.init_atmosphere..out run.log

4) Run mpirun -n 1 ./init_atmosphere_model |& tee run.log

5) Quick skim for issues grep -E “Bootstrapping|filename template|CFSR|CRITICAL|ERROR” log.init_atmosphere.0000.out
