cesm1.2.2

Hello CESM Community, I am a PhD student currently working on deep-time paleoclimate simulations, specifically investigating the hydrologic cycle and coastal upwelling dynamics during the Proterozoic eon. I am setting up iCESM1.2 to utilize both the water isotope tracking. System and Case...

Hello everyone, I am trying to run an experiment with CESM 1.2.2 using the LW-off option, but I am having trouble turning it off. I attempted to modify some .f90 files (following）, but it seems not to work. Could anyone give me guidance on how to properly disable the longwave radiation in this...

Hello everyone, I'm using the CESM 122 version for my work. I'm running a 100-year simulation with user-defined COMPSET "2000_CAM5_CLM45_CICE_DOCN%SOM_RTM_SGLC_SWAV" and setting CCSM_CO2_PPMV=400. My simulation ran for 51 years, then suddenly it halted, prompting an error saying "forrtl...

Requesting assistance, thank you very much! 1. When creating a new case in CESM1.2.2 using -compset B1850W, which grid should be selected and what should be chosen for -res? How can the case be successfully created and configured? 2. In CESM2.2.0, to modify the initial files, which folder...

Hello everyone, my CESM version is 1.2.2. I want to modify SST boundry data to discover observational SST's(from 1979-2021) impact on atmospheric variability. To achieve this goal, i use FAMIPC5 compset to simulate the period of 1979-2021 and modify user_nl_cam to the same emission...

I used CESM1.2.2 to simulate the changes in CO₂ concentration, and I found that TLAI became smaller. Can this phenomenon also allow more incoming shortwave radiation, leading to increased soil water evaporation? Thank you~

What version of the code are you using? - CESM 1.2.2 Describe every step you took leading up to the problem: - I went through the online documentation to download cesm 1.2.2 on derecho but did not work. Also went through relevant question is the forum but did not find relevant things...

Hello everyone! I am currently using CESM 1.2 to create an experiment, and here are the steps I followed: 1、Navigated into the "scripts" directory to create a new case. cd /work/software/cesm/1.2.2_openmpi2020/scripts/ ./create_newcase -case ~/ymt/cases/control_B1850_2000.001 -compset...

Hello, I'm trying to run a simple pre-industrial control test case with CESM1.2.2 and CAM5 with COSP enabled but I'm running into an error at the build step. For reference, I have no problems running B-compsets with CAM4 and COSP on my machine, this build error only arises when I use CAM5...

Hello everyone, I'm attempting to run CESM1.2.2.1 on Derecho and have encountered build errors. Does anyone have suggestions or insights on resolving this issue? Thank you! >> ./test.build: CESM BUILDEXE SCRIPT STARTING rm: No match. COMPILER is intel - Build Libraries: mct gptl pio...

Hello, I'd like to calculate u, v wind components at 10m using 10m wind speed, and zonal and meridional wind stress components. This is because u, v wind components at 10m do not save in our runs. Theoretically, zonal and meridional wind stress components can be explained as follows. TAUX =...

I'm running CESM 1.2.2 with CAM5+trop_mam3+prescribed_emit ncl. After the task completed, I checked the atm.log file and cesm.log file and found these problems below: This is from atm.log file: And one from cesm.log file: It seems that some strange data have been written into the file, but I...

Hi there, I can successfully build a case, but after I submit the case, it completed very quickly (running about 5 minutes). I checked the atm.log file, it shows the problem below. I have checked the atm_in file and compared it with my script to check the variable name I used, and I didn't find...

Hi! I want to got the Total grid-box cloud ice water path (TGCLDIWP) or cloud water path for different tags. I added the output variable in the same way: fincl1="TGCLDIWP_NAO","TGCLDIWP_PAC"...... However, when I submit the simulation, it will report an error: FLDLST: TGCLDIWP_NAO in fincl( 1...

Dear CESM community, I have been trying to port CESM 1.2.2 on a new machine (the Irene machine of the TGCC in France, in case anyone knows it). I encounter an error during the build phase. I have been trying to solve this problem for more than 10 days, but now I am totally stuck. I would really...

Dear all, I am trying to learn how to add a passive tracer in the CAM module but am still confused after some previous posts: (e.g., CAM tracer https://bb.cgd.ucar.edu/cesm/threads/help-about-passive-ozone-in-cesm.2595/...

Hi! I ported the iCESM1.2, after i set the variables in env_build.xml, env_mach_pes.xml and env_run.xml, and called the cesm_setup again,there was the error: Running preview_namelist script Illegal variable name. ERROR: /home/user/iCESM1.2/scripts/test1/preview_namelists failed: 65280...

I am using CESM1.2.2.1 for deep time paleoclimate, and I would like to compile the runoff_to_ocean utility on Cheyenne. Unfortunately, I am running into this error. ld: /glade/u/apps/ch/opt/netcdf-mpi/4.6.1/mpt/2.19/intel/17.0.1/lib/libnetcdf.a(libdispatch_la-dfile.o): in function...

Hello, DiscussCESM I'm a Ph.D student at Peking University, and I'm doing some research in geological deep-time paleoclimate by CESM1.2.2. I revised the land_sea mask, elevation, and kmt (in ocean) before I build the run. But, no matter how I try to make runoff downstream (resolution at...

Hello, I'm a new user. I got some problems when performing ./test.build. All my command are as follows. cd cesm1_2_2/scripts ./create_newcase -case test -res f19_g16 -compset X -mach bella cd test ./cesm_setup ./test.build Then I got errors...
