cesm2

Dear CESM/CAM community, I am aiming at using relative relative humidity output from CESM experiments. In doing so, I encountered problems (comprehension issues) with the RHREFHT field: When performing preliminary analyses (using the CESM2 Single Forcing Experiment), the relative humidity...

Hi,all! I try to use the SpinupStability_v10.ncl to evaluate the state for Spinup model. But i got the information "fatal:No valid instance of variable TOTECOSYSC found in file list" and "fatal:["Execute.c":8637]:Execute: Error occurred at or near line 166 in file SpinupStability_v10.ncl"...

Hi,all, I want to know how to calculate the surface temperature(TSA) in CLM so that I can find the factors related to surface temperature(It's like the effect and control of wind speed and low clouds on surface temperature) I don't know where to find the code and the formulate. Any note or...

Hi all, I'm wondering if there is a version of CESM2 on git that is out-of-the-box compatible with Derecho? If not, does anyone have advice on how to edit the config_machine.xml file so that the model can run on Derecho?

Hi,all! I wanna ask the question:how did the lowcloud effect the surface temperature? Because I find the increase of lowclloud fraction can decrease the Tmin in CESM2.1.3. The result not consisit of my common sense. We usually think the thick and low cloud can keep the surface warm in the...

Hi all, I'm trying to install CESM2.1.4 on the DOE machine Perlmutter (CPU nodes). I've updated the config_machines.xml and config_batch.xml files. However, I'm unsure how to modify the config_compilers.xml to fit Perlmutter-cpu. After using the revised config_machines.xml, config_batch.xml...

Greetings, I am looking if there is a quick and easy way to have the aerosol radiative properties (tau, SSA and g) for each SW band in the output files. I tried something like this in the user_nl_cam when I run CESM2.2: avgflag_pertape = 'A','I' nhtfrq = 0, -3 mfilt = 1, 8 fincl1 = 'tau'...

Hi all, I have a run of CAM6-Chem from CESM2.1.3 with coupled land (CLM5-BGC-Crop) and oceans (POP2) forced by SSP1-2.6 GHGs and land use. I wanted to look at some convection parameters, however the output from the model for CIN was 0 everywhere and the output for CAPE was an order of magnitude...

Hi all, I ran a CAM-Chem case in CESM2.1.3 and output CIN, but all values were 0. I've seen elsewhere that this is a known issue with CAM-Chem and that CIN tends only to be output by WACCM (I guess this is my fault for going for the cheaper model). I'd like to calculate CIN manually but the...

Hi, I am attempting to run an CESM2.1.3 case (compset BSSP126), and I encountered an error about half an hour after submitting the case. The CESM log reads: 2 IMOD, NAPROC, NBLKRS, NSPEC, RSBLKS= 1 72 9 600 5 600 5 1 IMOD...

Hi, I made some changes in user_nl_clm as: hist_fincl1 = 'FireComp_BC', 'FireMech_bc_a1', and so on other variables, but it seems it didn't find FireMech_. I can see 'FireMech_bc_a1' in the list in the link below, but why is it unable to find it? There is no problem with FireComp_BC, but only a...

Hi all, We've successfully ported CESM2.1.3 to an HPC. Alas, said HPC was recently taken offline for various 'upgrades', and CESM2.1.3 no longer runs properly. After an extended session of whack-a-mole with various error messages, I've come across one which has me stumped. A test case using the...

Hi,all! I'm using F2000climo to simulate global changes from 2000-2050, I now want to output the 2000-2050 surface coverage dataset, what variables should I pick to output? Is it in the CLM component?

Hi, I have recently conducted simulations using CLM5 in CESM2.2.0, and I am particularly concerned about the emissions from land fires. I compared several species using both the GFED4 and CMIP6 biomass-burning emissions files. While the emissions of all other species appear to match reasonably...

Dear all, How can I get the input data for soil type (such as sand, silt, clay, et.al) in LUMIP (in experiment ID of hist-noLu,ssp370-ssp126Lu), CMIP (historical), and ScenarioMIP( ssp370). Thanks.

Hello! I have a query about the variable Pr (total precipitation or precipitation flux in the standard name) of the CESM2-FV2 model under the ssp585 forcing scenario. Currently, this variable is absent on the ESGF portal. Will it be made available in the future? Thank you!

Hi! everyone. I got a ERROR: Unknown error submitted to shr_abort_abort When CESM2.1.3 RUN. The log file in the attachment. I spin up 50years and change the surfdata in CASE test612 ,see the posthow-to-generate-surface-datasets-using-my-own-land-use-data. Now, I create a new CASE test620 and...

When running simulations with volcanic forcing in a fixed sea-surface temperature condition to get an estimate of the forcing, what output variables are the appropriate ones to use? From what I understand, the standard way to do this is to calculate it as the sum of the shortwave + longwave...

Hi, While running the clm5.0.03. The model setup and built has been successful. When I submit the case, it shows the 'run command is mpirun -np 4 /home/clm/cesm/scratch/xinjiang_1/bld/cesm.exe >> cesm.log.$LID 2>&1 ERROR: RUN FAIL: Command 'mpirun -np 4...

Hi all, I'm working on a regionally-refined spectral element grid and my case has failed with what looks like a fairly general MPT error but it's not one I've seen before, and the usual 'search for error message in CESM forum' approach hasn't been useful. The case runs OK for 3 months. After I...
