how to read atmospheric forcing with CLM4

[wangdag@mail_sysu_edu_cn]

I am trying to figure out how the offline CLM4 (under the framework of CESM1.0.4) read the atmospheric forcings, but with no luck. In CLM3, atmdrvMod.F90 is designed to read the forcings. I wonder if there is similar module in CLM4. Thanks

Dear Dagang,

The CESM operates in a single framework that always couples active components through the coupler. When you run an "i" case, the clm receives atmosphere data through the coupler from the data atmosphere model (datm). Therefore, the datm reads the data now rather than the clm.

Sam, thank you for the quick reply. Is datm_comp_mod.F90 (models/atm/datm) the module for this purpose? Thanks

I think so, but keep in mind that I'm not very familiar with the datm.

Dear DagangI want to add a new variable into the atmospheric forcing data, could you please give me some general ideas or hints for how to do it? I am comfused about the processes of reading the forcing data in offline CLM. I appreciate your time very much! Thanks
