See Part One for hints on how to fetch CSFR data in an automated way. You only need two of the WRF presets, since SST is included in surface files:
- pressure level data (pgbh06 files)
- surface and fluxes (flxf06 files)
I rename the files and strip off the trailing date which refers to how they are archived e.g.
201001011800.pgbh06.gdas.20100101-20100105.grb2 ------> 201001011800.pgbh06.gdas.pressure.grb2 201001020000.flxf06.gdas.20100101-20100105.grb2 ------> 201001020000.flxf06.gdas.sst.grb2
Then you need to run ungrib.exe twice:
Vtable.CFSR_press_pgbh06 --> Vtable
Vtable.CFSR_sfc_flxf06 --> Vtable
That should create two sets of intermediate files prefixed PRESS and SFLUX. Next run metgrid with the
fg_name = 'PLEVS', 'SFLUX',
Et voila! It should work.
