Hi all, I'm running a coupled atmosphere-ocean compset in CESM2.2.0 on Cheyenne. I have successfully run this compset for 10 years - in the next run of 10 years it crashed at year 18. The error in the cesm.log is: WHL, oc_tavg_helper is already associated; reset the tavg fields 0: sysmem...

Hi all, I'm trying to build a transient run based on an existing non-transient run I made previously. The problem I am having is trying to turn off 'ext_frc_cycle_yr', 'srf_emis_cycle_yr', etc. The model doesn't run because these values are fixed at 2010, even though I have not set them in...

I am receiving the following error after starting a run, before the first timestep occurs, at the ingestion of the inital data file that I'm pointing to via NCDATA in user_nl_cam: read_initial: model parameters do not match initial dataset parameters Model Parameters: plon = 1...

Hi, I would like to do a transient run of CESM2.2.0 over the period 2015-2100 using SSP3-7.0. I plan to use a transient land use change scenario in CLM5 ('flanduse_timeseries'). However, the namelist setting 'sim_year_range' in CLM5 only permits running over the period 2000-2100. As I'm not...

I just started learning how to use CESM. I have successfully ported CESM2.1.1. And the test ran successfully at that time. Today, I tried according to the official website case, but there was an error in the final operation. This is my case：./create_newcase--case Exercise1 --res f19_g17...

Hi all, I was able to successfully build a case but when submitting the case I got errors messages. I am not sure what is the problem. Do you have any suggestions for me to try? Thanks very much for your help, jia

Hi, I'm new to CESM2. Now I have errors in ./case.build, the errors are as follows: Creating component namelists 2022-06-08 15:32:12 atm Calling /global/home/zhanggw/CESM2/my_cesm_sandbox/components/cam//cime_config/buildnml ...calling cam buildcpp to set build time options CAM...

Hello! I am facing problems when using high-resolution atmospheric forcing (1440 x 721) in the datm component while running NEMO-CICE configuration. Initially, with my default flags for compilation, it showed a segmentation fault. The message was "[n086:344621:0:344621] Caught signal 11...

Hi all, I'm working on Cheyenne and currently can't submit anything into the batch queue. When I run qcmd -- ./case.build to compile a model run (CESM2.2.0), I get: Connection refused qsub: cannot connect to server chadmin2.ib0.cheyenne.ucar.edu (errno=111) Error: PBS could not successfully...

Hi all, I have a CESM2.2.0 run on Cheyenne which crashes after submitting, but I can't see an obvious error source. It's a land-atmosphere only run based on the FC2010climo compset. The error message in the cesm log is the usual: 0:MCT::m_Router::initp_: GSMap indices not increasing...Will...

Hello, I am currently attempting to port CESM (v2.1.1) to a new machine which uses Slurm for queue management, but which does not use a module system. As such, I am struggling to understand how I can supply information about my environment to CESM when running a case. I am able to set up a...

Hi all, I have done some runs with CLM5 in land-only mode and have a result I'm not sure how to explain. The runs are at 0.5deg resolution over a regional domain covering sub-Saharan Africa over the period 2015-2100. We have used SSP3 anomaly forcings and done runs with CO2 increase only, CO2 +...

Dear CESM community, We have been trying to set up CESM v2.1.3 on the new system at our institute but we're facing a lot of problems. As it stands now, we are able to create a case and build it successfully. When we submit the job, an error shows up (segmentation fault) in the log files...

Hello, I am attempting to do a branch run off of a CESM2 LENS ensemble (b.e21.BHISTcmip6.f09_g17.LE2-1001.001), but I keep getting the following error when I run it: 1: NetCDF: Variable not found 1: pio_support::pio_die:: myrank= -1 : ERROR: nf_mod.F90: 731 : 1: NetCDF...

Hi, can I change the fsurdat from surfdata_0.9x1.25... to landuse.timeseries_0.9x1.25.... I tried changing it in CESM2.1.3 with ISSP370Clm50BgcCrop compset but encountered some problem: Default: fsurdat =...

Hi all, I'm running CESM2.2.0 and am looking at the effects of land use on BVOC emissions under different climate scenarios. I have generated surfdata files for CLM5 which I thought were prescribing LAI, as they contain the variable 'monthly LAI'. However, when we run experiments with different...

Greetings, I am modifying a module in the CAM6.0 (nudging.F90) and in during the process to build a case I get this message and the case is not completely built. Somebody knows why this directory is not created? Thanks in advance

Greetings, We are trying to make some code modification in some modules in CAM6.3 in order to customize some cases we want to run. The reason we are doing that it is because we need to specify some inputs which are not available as CESM has been built. Therefore, we found that if we want to...

Hi all, I'm working on change land-sea distribution in the CESM2.1.3, I have generate new ocean domain file and land domain file, and mapping files. The error happened in the run time, viewing the cesm log it says: ENDRUN: ERROR: ERROR in surfrdMod.F90 at line 384 ERROR: ERROR in...

Hi all, I'm working with the 1D PFT-level output for CLM5 for the first time. I am interested in plotting a timeseries of some PFT-level variables over my domain. I can see in the variable list that my history files contain a variable called 'pfts1d_wtgcell' (PFT weight relative to...
