cesm2.1

Hi everybody,We are trying to build a first case in CESM2.1.3 to our new supercomputer FinisTerrae3, at the Galician Supercomputing Centre. When running the case, it fails because an ERROR MAPZ_MODULE (see below). Does anyone know how to fix this error? Thanks in advance. (Opening file...

Hi,all! my CESM version is 2.1.3.I wonder if CESM can have SSP scenarios that can be run with few landuse PFTs? The current SSP scenarios have a lot of land use categories set up, with 78 for CROP. Are there any SSP scenarios that can be run where the land types are not as detailed? (For...

I am trying to do a branch run based on the f.e21.FHIST_BGC.f09_f09_mg17.CMIP6-AMIP.001 restart files (1955-01-01-00000) with CESM2.1.5. The case was created and the model was built all successfully, but after ./case.submit I got the run aborted, with errors from the cesm.log as...

I have a question about whether there's a need to spin up for branch runs. Specifically, I am using a restart file dated 1955-01-01, but the STARTDATE is defaulted to 1979-01-01 and cannot be changed due to the branch run's constraints. Can I assume that performing a branch run from a preset...

Hello, everyone! I ported cesm2.1.3 to my machine. I want to use WACCM-X to simulate the ionospheric field for 2020-2030. But the default compset cannot support this. I don't know what to do. So I hope to get some help here. Thanks everyone for your help!!!

I'm having some issues downloading input data. I am following this page to do a single point clm 5 run on cesm 2.1.5. I know support for specifying PTS_LAT/PTS_LON in create_newcase was dropped from cime at some point, but I can just change it after the case is created. # create the test...

Hi all, I have a transient historical run in CLM5 starting in 1901 which fails after the first few timesteps or so. The error in the atm.log is (shr_dmodel_readstrm) file ub...

Hello, I am trying to run the "fixed sst" aquaplanet (compset QPC6 --res f19_f19_mg17) experiment on CESM 2.1.3. To explore if my control runs look the same or not I have conducted the same experiment twice without changing any configuration for 4 years and have discarded the first 6 months as...

Hi, I tried to run I2000CLM50CN composet for ten model years without making any modifications. However, when I checked the output TLAI or GPP, I found that its value was normal in the first year, but it began to decline rapidly in the second year and approached 0. I understood that this meant...

Hi,all! I look through the page and I want to know what's Initialization Time? For FHIST_BGC, the Initialization Time value is HIST. Does means the timeseries of inputdata is 1850-2000? If I want to set the Initialization Time by my own, the parameter is "RUN_STARTDATE"? Where can i find the...

Hi,all. I changed the fsurdata of amazon area in the post. I run a control test using the default as F2000climo. the changed test using F2000climo,but I changed the fusrdata in amazon area. For the changed test, I spinup 50 years. And I continue to run 50 years. For the control test, i just...

Hi,everynoe. I run a compsat F2000climo for 1 month. Till now, i took nearly 18hours. Why take so long? Here is my detial for run the model: Here is my time record:

Dear all, I am trying to set up CESM2.1.3 on a new cluster. Because I kept seeing the "NetCDF was not complied by the same version ..." error, I re-installed the NetCDF-c and Netcdf-fortran using the intel compiler. However, I now see a new error that says...

Hi all, This might be a question with a 1-word answer, but just in case it's not: Is it possible to set one part of the CESM2 to only save output within a given domain? I would ideally like to save a couple of fields from CAM at hourly temporal resolution but only between 40S and 80N. The...

Hi, I'm trying to install CESM2.1.3 on the UK HPC ARCHER2. I have successfully run checkout_externals so should have the model working, but apparently I need to set up a programme called cpnrc. When I run the command ../configure --macros-format=Makefile --mpilib=mpi-serial I get the error...

Hi, I'm running a fully coupled simulation at 2 degree resolution (compset: 1850_CAM60_CLM50%BGC_CICE_POP2%ECO%ABIO-DIC_MOSART_CISM2%NOEVOLVE_WW3_BGC%BDRD, resolution: f19_g17), as a hybrid run branching from year 401 of the 2 degree PI control (b.e21.B1850.f19_g17.CMIP6-piControl-2deg.001)...

Dear Sir/Madam, Hello! I am trying to use the PORT (Parallel Offline Radiative Transfer model) aiming to get the radiative forcing, following the instructions from Example: Using PORT to study flux differences due to 2 x CO2. I successfully passed the ./case.setup and ./case.build (with the...

When I run ./mksurfdata.pl -r usrspec -hirespft -usr_gname 0.05x0.05 -usr_gdate 210328 to make surface map at 0.05 degree, there exist an error below ------------------------------------- Attempting to make Topography statistics..... domain_read_dims_1d read 1-d length from num_pixels...

I am trying to write out the variable WTT in both the monthly averaged and daily averaged files. As per this documentation I thought adding a _2 suffix is required if you want to write out the same variable in multiple output streams. For example, I have lines like these in the file...

We plan on using up to 40 cores on a linux cluster, with a focus on CESM 2.1 for short runs of a coarse resolution atmosphere model – see attached for the describe version file. (I was helped in forum posts around July.) I would like guidance on what tests of our installation should be run...
