    How does CESM handle "parameterizations" to incorporate inputs from unresolved physics at the subgrid scale

    I was watching some of the NCAR CESM 2022 tutorials/introduction videos, and they are really helpful. One issue that Peter H. Lauritzen raised when discussing the dynamical core of the CESM 2.2 model as well as the upcoming spectral elements core was this idea of "parameterizations" for...

    slflx_cg_PBL seems empty; possible to output counter-gradient flux?

    I am analyzing terms that contribute to the vertical mixing temperature tendency DTV in CESM1-CAM5, and in particular would like to get a measure for the counter-gradient flux of heat / non-local transport. slflx_cg is defined as kvh * cgh, the eddy diffusivity of heat times the counter-gradient...

    What contributes to DTV, the vertical mixing temperature tendency?

    I am analyzing the temperature tendency contributions over continental North America and the ice-covered Arctic during winter in CAM5 (CESM1-CAM5, F_1850_CAM5 compset with prescribed SSTs and sea ice, constant pre-industrial CO2), often within the first couple of model layers near the surface. I...

    Modify surface albedo

    Dear CESM team, Hello,I want to modify the surface albedo of some regions, how do I need to modify in the source code. It will be very appreciated if anyone could guide me on how to implement modifications (mentioned above). Thank you very much! Best, jia liu
