Hi. We are using CESM 1.2.2 with coupled CAM-CLM to investigate interactions between atmosphere and land model. We are trying to add a new atmosphere to land input to test some kind of impact of near surface air pollutant on vegetation. But reading in data from atmosphere to coupler then to land model is not successful. Any advice is welcome.We modified some modules trying to achieve this. Firstly in src.drv, we modified seq_flds_mod.F90 by adding some fluxes related to the air pollutant, by calling seq_flds_add. Basically, we imitated the treatment of downward longwave heat flux. Secondly in src.clm, we modified following modules, with similar treatment to other a2l fluxes:lnd_comp_mct.F90clm_cpl_indices.F90clm_atmlnd.F90And then we tried to use this variable a2l%forc_xxx in another module to impact a land surface process. But it turned out that the reading in from atmosphere (through coupler) to land failed that all of the values are 0. Can anyone help us out here? Thanks a lot in advance.
