Does SE dycore support compset BW1850? what is the configuration if supported.

Dear All, I'm trying to run an aquaplanet (QPC6, a compset I have used extensively with f19 resolution) simulation on a custom grid using CESM 2.1.3, but the case fails on execution. I have setup the custom 2x20 grid following 3.2 of these instructions and with guidance on this thread. I am...

I've been working on getting the CAM diagnostic code up and running, but I keep running into this error message: Traceback (most recent call last): File "./run_diag", line 55, in <module> from CamDiag import end_diag_script ImportError: cannot import name 'end_diag_script' from 'CamDiag'...

Hi all, I am an undergrad at Iowa State University that is looking to utilize CAM6 outputs to compare against observational datasets for a project. I am looking to work with data from the CAM6 runs with prescribed monthly SST's. I have been able to easily locate the available diagnostic...

Hi there, I am doing a nudging experiment, in which I want to nudge a sensitivity run to a control run (both runs are done with CESM2.1.3). I am running into all kinds of errors when trying to generate the required target data. Below are my questions arising from some of the errors: 1. are...

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...

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...

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.

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...

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 Several data sets have been archived to the Research Data Archive 345.0.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...

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...

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...

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