Hi all, I want to prescribe land surface temperature to drive the model, just like prescribe the SST. Hence I first run a 2-years control F_2000 experiment to output cpl hist files (xx.cpl.ha2x.yy.mm.dd.nc and xx.cpl.hl2x.yy.mm.dd.nc) in so-called "DLND_CPLHIST_DIR". Then I used these cpl hist...

Dear, All I'm trying to run CTSM model on LEVANTE cluster with my daily forcing, but I have several problems: 1. I don't understand why I have these Errors. However, I checked data and I have them into the folder. Also there is no problems with LND_DOMAIN_PATH and LND_DOMAIN_FILE. 2. When I'm...

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...

Hello everyone, I've been encountering an issue while trying to practise the "BGC_spinup" case on the website https://escomp.github.io/ctsm-docs/versions/release-clm5.0/html/users_guide/running-special-cases/Spinning-up-the-biogeochemistry-BGC-spinup.html When I submit case "BGC_spinup", the...

I am trying to run with my own regional 0.5*0.5 degree resolution based on the I1850CLM45CN compset, set RTM_MODE=ACTIVE. I used the "ncks" command to clip the global rdirc file to the area I am run trying to run on Many errors occurred when the model is actually run... So I want to know...

Hi, everyone, I'm running CESM2.1.3 with the defined compset BC5L45BGC (longname: 2000_CAM50_CLM45%BGC_CICE_POP2_MOSART_SGLC_SWAV). After submitting the job, the model encountered an error stating "Error in entering/exiting spinup. spinup_state != restart_file_spinup_state, but do not know what...

Hi, I would like to know what variables can be output by running CLM5, and where can I find the information

Dear All, I am running two FHIST_BGC cases to study the impact of LULCC on radiative forcing of GHGs in global, without considering their feedback. This needs GHGs to be sent from the land to the atmosphere, and not from the atmosphere to the land. The default CCSM_BGC = CO2A, it says "adds...

Dear all, I would like to modify the radiation reflected by the surface to the atmosphere. Where should I change the code? Thanks very much

Hello, I want to do a set of AGCM abrupt4xCO2+uniform 4K SST warming large ensemble simulation branching off from a control run. The goal of this experiment is to look at the instant atmosphere circulation responses to both SST warming and directive radiative forcing, so changes in every hours...

Dear all, I found that CLM was one of the participants submitting simulation results for the Global Carbon Budget 2021 (GCB2021) report. Now, I want to do some experiments (e.g., Modify some input data and re-run the model to find out the impacts of changing these inputs) based on the existing...

HI, I'm getting the following reproducible error in CAM while running a CAM6 f09 FHIST case with cam_cesm2_2_rel_03 (I think). Oddly it is able to run over 10 years before this error. The modifications I make are 1) using coupled CESM2 SSTs and sea ice rather than observed and 2) masking out the...

With the 15° longitude x 10° latitude grid (f10_f10_mg37), CLM output files have 360/15 = 24 longitudes, and they are as I would expect for a lower-left alignment (0, 15, …, 345). But there are 19 latitudes instead of 180/10 = 18, with latitudes -90, -80, …, -10, 0, 10, …, 80, 90. The...

I'm doing a 2-degree spinup of ctsm5.1.dev092. The 200-year CLM_ACCELERATED_SPINUP run went fine, as did the first 400 years of the second phase. Now I'm trying to do another 400 years, and I'm running into this error: 1229:MPT ERROR: Assertion failed at ibdev_multirail.c:4297: "0 <=...

I'm working to add an annually-output variable that gives the total "grain C to food" accumulated during each growing season. This will be faster and less error-prone than the usual method, which is to sum daily GRAINC_TO_FOOD across a growing season (after multiplying by 3600*24, or...

Hello, I am porting CESM 2.1.1 to another machine, and trying to run the FCHIST compset (1.9x2.5 degree resolution, 32 cores). I am using Intel's most recent compilers (2022.0.2) and OpenMPI v4.0.4. I'm finding a very strange error. During initialization, when CLM tries to regrid the initial...

Dear all, I am trying to submit a case created using compset 'ISSP126Clm50BgcCrop' in the containized docker version of CESM. The only setting I changed was the DIN_LOC_ROOT. The case create, setup, and build processes were ok. Here I attached the cesm.log file, FYI. Thank you!

I'm not entirely sure if this should go in the CLM or DATM forums, so apologies if I've guessed wrong. I'm trying to run PTCLM5.0 with transcient atmospheric CO2 concentrations. As per this guide, these are the steps I have taken...

I found the prescribed aerosol deposition data in 2000: “aerosoldep_monthly_2000_mean_1.9x2.5_c090421.nc”. Does anyone know any information about its used model/accuracy or any reference about this file? I also found a regridded version I also found a higher resolution version...
