cesm2

Dear all, I would like to do a fully-coupled simualtion with 2000 climatology with CESM2. I think I should use the BC5L45BGC, which like B_2000_CAM5_CN in CESM1? However, the supported level of BC5L45BGC is just 'defined', and BC5L45BGC does not have a Scientifically Supported Grids. If the...

Hi everyone, I've been working with the F2000climo compset and noticed that the input files seem to contain only twelve months of data, which I assume is circulated annually by the model. However, I would like to introduce time-varying SST and CO2 data in my simulations. To achieve this, I'm...

Hi, SOILLIQ and H2OSOI both reprsent the soil moisture. I would like to convert SOILLIQ (kg/m^2) to H2OSOI (m^3/m^3), which have different units. But I have no idea how to do. I am looking forward to any suggestions. Thanks in advance. Best, Kaiwen

Hi, I am trying to replace the soil moisture data with a soil moisture data climatology file in the fully coupled CESM1 or CESM2 (CESM1 is better) only when the model is calculating the heat flux (i.e., latent and sensible heat flux), and maintain the coupling state between the land and the...

Hi, I am trying to replace the SST data with a SST climatology file in the fully coupled CESM1 only when the model is calculating the heat flux (i.e., latent and sensible heat flux), and maintain the coupling state between the ocean and the atmosphere at the same time. In short, ocean component...

I am looking for some simulations and restart files: the FHIST or AMIP simulations with prescribed SST, running from 1850 to the 21st century. I can only find such simulations starting from 1950 to 2014. And I am unsure whether there are any simulations as requested, but any suggestions/help...

Hi, I am trying to replace the SST data input CPL with a SST climatology file in the fully coupled CESM1, and maintain the coupling state between the ocean and the atmosphere at the same time. So only CPL can see the SST climatology file when the model is calculating the heat flux. But I have no...

Hi, I managed to build the 'interpic_new' executable on Casper but have run into some further issues when trying to regrid a CAM-Chem IC file to an SE/RR grid. When running the initial command: ./interpic -t SE_template.nc -i area...

What version of the code are you using? CESM2.1.3 Have you made any changes to files in the source tree? No Describe every step you took leading up to the problem: If this is a port to a new machine: Please attach any files you added or changed for the machine port (e.g., config_compilers.xml...

I have some questions regarding the f.e21.FHIST_BGC.f09_f09_mg17.CMIP6-AMIP.0XX experiment series (001 to 010). What are the differences between the outputs and setups? They use the same F compset, but what other conditions were applied differently? As for the SST Inputs, are they all using...

Hello! I'm having some trouble running my case and am hoping someone on the forum can help me. I am using a virtual Linux machine running Ubuntu 22.04. I followed this guide to set the machine up and port CESM. However I chose to download a beta version as recommended by the visualCaseGen...

Hi all, I need to regrid a CAM IC file onto a regionally-refined CAM-SE grid for use in MUSICA. The file I am trying to regrid is: /glade/campaign/acom/acom-weather/MUSICA/init/ne30_ne30/f.e22.FCnudged.ne30_ne30_mg17.release-cesm2.2.0_spinup.2010_2020.001.cam.i.2019-01-01-00000.nc In order to...

Hi, I am looking to produce some nudged simulations in the CESM2 CAM6 subseasonal prediction system. Some of these will be everywhere (constant window function) and some will be in particular boxes using a window function horizontally and vertically (tropical troposphere, extratropical NH...

Hi all, I am doing some simulation experiments by changing PFT fractions to representing vegetation changes. I run simulations for 90 years with CESM2.1.2 ETEST(2000_CAM60_CLM50%SP_CICE_DOCN%SOM_MOSART_SGLC_SWAV_TEST) compset and with f19_g17 resolution. ./create_newcase --case ETEST_oldsurf...

Hi, everyone, I want to run a fully-coupled compset with external foring set as year 2000 level. However, I can't find a compset named as "B2000". I tried to run with the compset with longname "2000_CAM60_CLM50%BGC-CROP_CICE_POP2%ECO%ABIO-DIC_MOSART_CISM2%NOEVOLVE_WW3_BGC%BDRD". That is, I...

Hi all, I'm porting cesm2_3_alpha17e to my school server (Svante at MIT). It seems to run successfully, but no timing information. No timing output in the ./run/timing/. folder (nothing in checkpoints either), and no timing folder is created in the case directory (attached...

Hi all, I'm working on a port of CESM2.2.2 to the ARCHER2 HPC in the UK. I can build a case but the run fails with /work/n02/n02/jking/cesm/CESM2.2.2/runs/F2000_CESM2.2.2_test00/bld/cesm.exe: error while loading shared libraries: libpiof.so.4: cannot open shared object file: No such file or...

Hi, I am trying to download input data but get the following error when running ./check_input_data --download: Similar issues seemed to have been solved by modifying the cime/config/cesm/cesm_input.xml file, either by moving the svn download method first (here) or adding "/" at the end of...

Hi, I was wondering if there is some kind of hook where I can include a postprocessing script for CESM2 model runs. Ideally, this script would be called after a st_archive job is completed. I think this could be useful to save storage space: * only save wind speeds at desired levels...

Hi all, I'm trying to port CESM2.3.alpha17 to my HPC. When I run the ensemble test for F2000climo after installing the model: :/$CESMROOT/tools/statistical_ensemble_test> python ensemble.py --case $CESMROOT/runs/F2000climo_CESM2.3.alpha17.uf.0000 --ect cam --uf --mach archer2 --compset...
