    Looking for CAM history fields like clean sky downwelling solar flux at surface and TOA.

    Hello scientists, I am looking for cam history fields like clean sky downwelling solar flux at surface and TOA. The word "Clean" refers to all-sky flux without the aerosols effect or simply No aerosol sky solar flux. All-sky flux @ surface refers to Downwelling solar flux at surface (FSDS). Is...

    Understanding a vague error message

    I'm trying to run from initial conditions on file, pointed to by NCDATA. I'd like to verify that I've constructed the initial conditions properly by running a 30-day sim with FV3 (--res C24_C24_mg17) and --compset FADIAB. However, the run crashes immediately with a vague error message in the...

    Using CAM6 to run the same experiment with different cores, the results vary greatly

    Hello! I have a problem about cam6. I used cam6 to run the same experiment with different cores,but the results are quite different.Is that right? What should I do if it is wrong? I'm glad I got the answer.

    Why are FDS and FDSC constantly zero?

    Hi community, we are using CESM2.1.2 and CAM6 to produce 3 hourly output. Everything looks reasonable except Shortwave downward flux FDS and Shortwave clear-sky downward flux FDSC which are both zero at all timesteps and all locations. I am very new to the model but the run was started by...

    Data products from an 80 member reanalysis using CAM6 and DART

    We have recently finished a 2011-2019 reanalysis using CAM6 and DART. Several data sets have been archived to the Research Data Archive 345.0. They are designed to be useful to a variety of researchers in the CESM community. We're interested to know whether you feel that this would be a...

    Experience Modifying CDNC in CAM6?

    Hi all, I'm looking to run CAM6 (as part of a run on CESM2.1) and am looking to change cloud droplet number concentration geographically by latitude / longitude at specified atmospheric pressure levels (below 850 hPa). (I am trying to run a series of experiments to test ocean surface response...

    How to add water tracers to CAM6

    Hi there, I am trying to run a CAM6 case with water tracers on our super computer. I am using FHIST_BGC compset. I have tried to add commands ./xmlchange --append CAM_CONFIG_OPTS='-nadv_tt 3' and test_tracer_names='WT1','WT2','WT3' in the case run. But I get the following error messages in...

    SO2 external forcing for CESM2.1.1 (B1850) - pre-industrial conditions

    Hi, Could someone confirm whether the SO2 external forcing (emissions-cmip6_SO2) includes both volcanic continuous (degassing) and explosive (eruptions) SO2 emissions? Mvh, Jeani
