Hi all, I have run into an error when run ./manage_externals/checkout_externals Processing externals description file : Externals.cfg Processing externals description file : Externals_CLM.cfg Processing externals description file : ../Externals_cime.cfg Processing externals description file ...

Hi there, I am wondering if it is possible to get the 6-hourly CESM2 outputs of the CMIP6 project to derive the WRF model. A similar dataset (Bias-Corrected CMIP5 CESM Data in WRF/MPAS Intermediate File Format | OpenSky) has been proposed in 2015, but for the CMIP5 archive. Specifically, I need...

Hi all, I'm working with MUSICA and need to generate a topography file for my variable-resolution grid. I am following the instructions for the 'Topo' tool. When I run ./cube_to_target, the script fails with: error while loading shared libraries: libnetcdff.so.7: cannot open shared object...

Hello everyone, I am trying to run CESM2.1.3 at the resolution f05_f05_mg17. It seems there is no topo file corresponding to 0.47x0.63 available for CAM6 in https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/atm/cam/topo. I realize that the resampling tool in interpic_new can create my own...

Hi all, I want to conduct a set of large ensemble that are similar to CMIP6 amip-4xCO2. However, I don't know how the CO2 concentration is set in amip-4xCO2 as the prescribed CO2 concentration is different every year. The compset I am using is FHIST_BGC, and I guess I am supposed to change the...

Hello everyone, I try to get the output including GRAINC_TO_FOOD with 1/2 degree by CESM2.1.3. The surface file and landuse file corresponding to f05_g17 have been generated, and I run this case with compset HIST_DATM%GSWP3v1_CLM50%BGC-CROP_SICE_SOCN_MOSART_SGLC_SWAV and resolution f05_g17...

Hi all, I am using the CESM2 Large Ensemble dataset and wanted to understand the "sea surface height" variable, SSH_2. The dataset is in /glade/campaign/cgd/cesm/CESM2-LE/ocn/proc/tseries/day_1/SSH_2/. Is SSH_2 supposed to be the "dynamic sea level," referred to as "zos" according to CMIP6...

Hello everyone, I use release-cesm2.2.0 and try to get the outputs with 'GRAINC_TO_FOOD'. I run this case with CAM60+CLM%Bgc-Crop+initial file "b.e20.BHIST.f09_g17.20thC.297_01_v3.clm2.r.1979-01-01-00000.nc". Unfortunately, I encountered such error to stop the run. "lnd_import ERROR: Longwave...

I found the change in emissions is also changing the surface temperature even when the passive radiative forcing is True (chem_rad_passive = .true.). I am not sure what is driving this change in temperature in CESM2.1.3 (FMOZ compset; CAM4-Chem, CLM5). Are there any control options...

Hi CESM experts, I work at the Institute for Marine and Atmospheric research Utrecht (IMAU) in the Netherlands and I would like to rerun the following CESM2 case (b.e21.BSSP585_BPRPcmip6.f09_g17.CMIP6-esm-ssp585.001) which was run at machine Cheyenne...

Hi everyone. When I execute the command in CESM2.1.3: ./case.submit It report an error as below. But, if I submit my simulation using the command: pjsub .case.run The model can work. Here, I understand this suffix '--resubmit' is useless, as I do a 'startup' simulation with the resubmit option...

Hi there, I am trying to run CESM2.2.0. in Stampede2 TACC system. The model compiles, builds, and gets the data fine. But when I try to submit the sbatch script, it gives me the following message in the log file. Any idea about what is going on?

Hi everybody, when I running CESM2.1.3 ( --res f09_f09_mg17 --compset 1850_CAM40_CLM50%SP_CICE%PRES_DOCN%DOM_MOSART_CISM2%NOEVOLVE_SWAV ), I am going to use my own modified SST data to replace the original data of the model which is 'sst_HadOIBl_bc_0.9x1.25_clim_pi_c101028.nc'. However, the...

Hi all, I've made a regionally-refined grid using MUSICA by following the steps in the tutorial. However, case.build fails with: ERROR: Could not initialize Grids when I try to build the case. It's a case using the FCHIST compset and I'm running CESM2.2.0 on Cheyenne. I'm not sure where to...

Hi all, I have a user-defined CESM2.2.0 compset on Cheyenne which runs fine. However, after changing the initial condition files used, it fails to run beyond the first timestep with the following error in cesm.log: ERROR: component_mod:check_fields NaN found in ATM instance: 1 field Sa_z...

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...
