How to run CAMChem with MAM4 and offline meteorology.

[li230@illinois_edu]

Dear All, I'm running cesm1_2_2_CAMChem with FSTRATMAM4 compset, but I'm not sure how to run with offline meteorology, say ECMWF reanalysis field. Can anyone give me some hint?Thanks a lot! Yinrui

Hi Yinrui, you can run this compset: FSDSMAM which runs with offline meteorology. This is MAM3 but you can change it to MAM4, Simone

Hi Simone, Thanks for your suggestion!I wonder how should I deal with the namelist if I'm going to change MAM3 to MAM4? Can I compare the differences between the namelists of FSTRATMAM4 and FSDSMAM, and change anything related to mam3 to mam4? Moreover, can I sepcify the meteorology field that I'm going to use, say ECMWF reanalysis fields? I know it might be complicated to explain things above. I would be really appreciated if you can give me some general advice.Thank you! Yinrui
