Hello, I want to couple the machine learning model with the atmospheric model in the cesm2.1.0 simulation using F Torch. I have configured the F Torch environment and conducted offline tests which were successful. I would like to know where I can make the model also use the F Torch environment.

Hi, In cesm2.1.0, I mainly focus on cam. The default step size of the cam host model is 30 minutes. clubb is coupled with the cam host model six times during its operation, with a time step size of 5 minutes. Without changing the default step size of the cam host model, how should I output the...

What version of the code are you using? CESM2.2 and CAM6 Have you made any changes to files in the source tree? Changes in the nudging module and the dust scheme Describe your problem or question: From the documentation I see that besides the AODDUST, it is possible to get the AODDUST for...

Why is the 500 hPa geopotential height in the CAM5 simulation results so strange over land? The simulation of geopotential height in CAM6 is closer to ERA5, but due to the bias in CAM6's precipitation results, we have to use CAM5 for the study for now. The geopotential height variable (Z3) in...

What version of the code are you using? CESM2.2.2, CAM6 Have you made any changes to files in the source tree? Changes in nudging and CLM Describe every step you took leading up to the problem: I need to use ERA5 re-analisys files to nudge aerosols. Describe your problem or question: I...

Hello, I am working with the FWsc2010climo compset. The default resolution is f09_f09_mg17. For my application, I would like to use a more regular ~1° × 1° grid instead. From what I understand, this would require regridding all of the input data (initial conditions, prescribed ozone, CO₂...

What version of the code are you using? I am using CESM2.1.5 Have you made any changes to files in the source tree? I have not made any change yet Describe your problem or question: Dear CESM staff: I am working with the following component set...

What version of the code are you using? CESM2.2.2 Have you made any changes to files in the source tree? Changes in dust scheme and nuding Describe every step you took leading up to the problem: I need to create new emissions for current months of 2025 and I need some specific NCL libraries...

When simulating precipitation after 2015, the model results show that, compared with ERA5, the large-scale summer rain belt over China and adjacent regions is shifted northward, convective precipitation is relatively weak, and the western Pacific subtropical high (defined by the 5880-gpm...

I am a beginner to CESM, and am using CESM2.1.3 to run a CO2 forcing experiment. I would like to increase the CO2 concentration by 0.73% for 190 years to go from 284 ppmv (as set by co2vmr in the restart files) to 1135 ppmv. Can I use the following namelist variables to do so? Any suggestions...

I am currently using the CAM6.0 model and would like to calculate the apparent heat source and moisture sink. From previous discussions on this topic, I found some answers regarding CAM3: For temperature, the total physics tendency is PTTEND, where: PTTEND = DTCOND + QRS + QRL + DTV + TTGWORO...
