Meteorological data sets

[nuvolet]

Hi all,

I am reading the documentation for CAM6.0, and in chapter 7about input datasets, in section 7.5 for meteorological data sets it is claimed that CAM uses GEOS5 and MERRA2 meteorological reanalysis.

• How could I know which datasets are used?. Both?.
• How could I customize that input?
• Is possible to change it by an external datasets and how could I do it?

Thanks in advance

I can give you a high-level answer to your request about MERRA2 dataset use in CAM.

There is one F compset which utilizes MERRA2 and it is FCSD. To see the actual datafiles which are used, do the following:

./create_newcase --case test_fcsd --compset FCSD --res f09_f09_mg17 --compiler gnu --run-unsupported
cd test_fcsd
./case.setup
./preview_namelists

You may then inspect the CaseDocs/atm_in file and see which MERRA2 datasets are being used

I should point out that I personally have never run this compset and it is a chemistry/specified dynamics compset which may or may not be what you want to use. It does give you an example of MERRA2 dataset usage though.
