    looking for AMIP restart files

    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...

    How to change the sea upward flux in CPL in CESM1?

    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...

    Interpic_new question

    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...

    How to generate SST forcing dataset for running a CESM2 pacemaker experiment?

    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...

    Questions about the CMIP6-AMIP 001-010

    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...

    How to build interpic_new on Derecho

    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...

    Questions on CAM6 nudging parameters

    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...

    run ETEST compset with CESM2.1.2

    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...

    Can I use compset which is not scientific and tested when running CESM2.1.3

    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...

    CESM2.3 porting issue (no timing information)

    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...

    Run error - CESM2 can't find PIO library

    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...

    Error Downloading Input Data

    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...

    Can I configure cime to run a postprocessing script after successful archiving?

    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...

    CLM build error in CESM2.3 port

    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...

    Questions about hybrid and RUN_REFDATE

    Hello everyone, I am new to CESM. I have learned a lot from this forum, but I still have some questions about "hybrid" and "RUN_REFDATE". When i create a new case with ./create_newcase --case B1850 --compset B1850 --res f09_g17, and then ./xmlquery RUN_REFTYPE I expected it to return "startup"...

    Questions on NTASKS, ROOTPE, and submission

    I'm running an experiment,compset is BSSP126, but when I submit the job, I run into this issue where the coupling merge node calculates incorrectly. Here are the logs: mpirun detected that one or more processes exited with non-zero status, thus causing the job to be terminated. The first...

    Plot the wind direction for U10 variable

    Hi,all! I output the 10m wind speed by using U10 variable. Also, I output the TAUX and TAUY(Zonal surface stress) . TAUX and TAUY do not seem to be the U,V variables needed to plot wind direction. UBOT and VBOT seem to be the corresponding variables, but for heights higher than 10 m. Is...

    How to set up to run 2014 in Fclimo2000

    Hi,all! I've been having some problems lately. (1)Why did we set up Fclimo2000, to run 2000 alone, and are these kinds of results meant to explain anything? (2)If I want to run 2014 on its own, it's like "Fclimo2014".How do I accomplish this? (3)If I only change the surface data for the year...

    How to properly interpolate wind speeds to a specific height above ground level?

    Hello, I am working with ARISE-SAI-1.5 and CESM2-WACCM6-SSP245 model output, and I would like to calculate the wind speed above ground level, specifically 100 m. Besides the 10 m wind speed variable that is readily available, zonal (U) and meridional (V) winds are available on model levels...
