Recently, I run a case with modification on POP SourceMods - forcing_coupled.F90
allocate(Hosing_fw_flux(nx_block,ny_block,max_blocks_clinic))
forcing_file = construct_file('nc', &...
Dear CESM community,
I’m currently working with CESM1.2.1, specifically its POP2 component, and I have two related requests:
1. Generation of solFe_scenario4_current_gx1v6.nc
The model automatically reads in soluble iron deposition from a file named solFe_scenario4_current_gx1v6.nc, which...
Dear all,
I am confuesd about how POP handles land in his SST calculations. I am using B1850 from CESM2.1.3.
I check o2xavg_So_t, which is the SST passed by POP to CPL. I found the value on land as well at 273.15K (see the Fig below).
I checked the code in the ocn_import_export.F90 file for...

Recently, I use restart file and boundary conditions from cesm 1.2 to run iCESM1.3 -- res f19_g16 --compset 1850_CAM50_CLM40%SP_CICE_POP2_RTM_SGLC_SWAV
I always come into crush at random-like time because of Incorrect TLT computations in POP2, always several years after continue run.
Sometimes...
Hello. I am trying to compute a heat budget for a small region of the equatorial Pacific (e.g. 5S-5N, 120-140W), but I am having trouble with the advective terms. I have read several other threads with similar questions (here, here, and here) but I am still not obtaining reasonable values using...
What version of the code are you using?
The most up to date CESM2LENS version whose variables are publicly available
Have you made any changes to files in the source tree?
No
Describe your problem or question:
I am looking for some clarity on the ocean component used in CESM2LENS, POP2. I...
What version of the code are you using?
release-cesm2.1.5
Running on UK Archer2 super-computer
Describe your problem or question:
I am trying to get instantaneous values of DIC and DOC out of the CESM2 POP model, so I can compute Carbon budgets. I have modified ocn.ecosys.tavg.csh to that the...
Dear fellow data processors,
I've been running into an issue with calculating zonal mean heat convergence in the ocean in some custom simulations I've run.
Apparently, this was calculated for different FAFMIP and OMIP models as...
Hi! I'm currently planning to do a water hosing experiment (mimicking Antarctic meltwater) using the CESM2.1.3 model.
I just read the CESM2.1.3 FAQ and found the method (change below code in forcing_coupled.F90.
But, I'm not sure how I can change the freshwater in specific region in this...
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...
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 all,
I am trying to run a LGM simulation with CESM1.2.2 and B1850 compset. I have a set of ocean restart files (gx1v6) and corresponding mask files to take advantage of. Unfortunately the bnd_topo file for CAM on hand has land/sea mask slightly different from the ocean files due to different...
I barely know this file format, except that it is probably a binary file, and I have no idea how to deal with it. Can Python/MATLAB/NCL... open it? What should I do if I want to modify the values in this files? Is it possible to transform .ieeer8 to .nc?
Any messages about it is appreciated...
I tried to replace the system's own POP2 component with another ocean component on cesm1_3_beta17_sehires38, and created a case where compset was GIAF and res was f19_g16_rx1, but the following random errors occurred when the run process was repeatedly executed. May I ask why? Using the same...
To Whom this may concern,
I have ported CESM2 to the Niagara supercomputer on SciNet (part of Digital Research Alliance of Canada). The config* files are attached, compiler used is intel with mpilib of intelmpi. I have also attached the log files. This includes the atm, cesm, cpl, lnd, ocn, and...
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!
Thanks for opening this thread. I am running fully coupled climate simulation (use B1850, ) with CESM1.2. The ocean tracer module is set to "iage ecosys" for this simulation. The model has been running successfully for 3000 years.When I change to 'hybrid' continue to run the...

Thanks for opening this thread. I am running fully coupled climate simulation (use B1850) with CESM1.2. The model has been running successfully for 3000 years.When I change to 'hybrid' continue to run the next (I also change the dtime by modifying ATM_NCPL in env_run.xml file...
Hi NCAR paleo friends,
Recently I am using the NCAR paleotoolkit to create a binary KMT file from a .nc one.
I used this code:
https://github.com/CESM-Development/paleoToolkit/blob/master/cesm1_2/ocn/mk_ocn_grid/gridkmt_nc2bin_src/gridkmt_nc2bin.f90
However, when I look at Line 37, this...
