Hello, I want to change the dynamic variables, such as temperature or wind, in particular model time. I found that dyn_in and dyn_out are used to contain the dynamic variables, thus dyn_out%t3 represent the temperature field. But after I overwrite/change the values of the dyn_out%t3, it seems...

Hello, everyone！Thanks for opening this thread. I need your help. I am running fully coupled climate simulation (use B1850 compesite) with CESM1.2. The model has been running successfully for 3000 years.When I change to 'branch' continue to run the next, running successfully for six months and...

Dear Helper, I want to run a case with 'f09_g16' grid and 'FMOZ' compest in CESM1.2.2, the default FMOZ suits with 1.9x2.5, so I modified the file '2000_cam4_trop_chem.xml' to match with f09_g16, but there is still a error about SST and ice coverage data, it shows "application called...

Hi All, I have successfully setup CAMRT to run offline with CESM1.2.2. Following the instructions from here and its source publication. Running PORT requires a high temporal resolution (~every day and a half) radiation data to be fed into the model. I have been able to run PORT with perturbed...

hi, I encountered the following error message after the model run for around 1 min. There is no error during case create/build/submit but during case run. I am not sure what is causing this problem. I am using CESM2.1.3, CAM4-chem tropospheric MOZART, CLM5, FMOZ compset. Could anyone suggest to...

Hi, In CESM2.1.3 (FMOZ compset, CAM40%TMOZ, CLM5) do we manually need to turn on climate-chemistry interactions (i.e., simulated aerosols and ozone can actually affect climate?), and two-way nitrogen fluxes (i.e., does your simulated nitrogen deposition actually affects the land?). Where can I...

Hi, I am currently using CESM2.1.3 (CAM4, CLM5), FMOZ compset. I want to get O3 hourly output in the hist file and the rest of the other variables in the monthly output (default). I made some changes in user_nl_cam, but I am still getting h0 files as model output and on checking the output .nc...

Hi all, I'm running CESM1.2.2 with CAM4. I wish to output 3D monthly averages of transient-eddy fluxes in the atmosphere (water vapor, temperature, geopotential, momentum). Are these fluxes available as standard History Fields? I had a look in the CAM4 documnetnation but couldn't find them... If...

Dear Forum Members,I am using CESM 1.0.4 and CAM4 to study the effects of sulfate aerosols (both background and volcanic size) by prescribing them in stratosphere. 1) Could somebody provide a reference on how longwave and shortwave properties of sulfate aerosols are parametrised in the model...
