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...

Hello, everyone！ 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...

I want to run ocean-only mode, use compset C, with my own forcing data. After created new case. I am tying to force the ocean model with external surface heat flux (SHF) and surface fresh water flux (SFWF). The forcing_shf_nml consist of SST, air temperature, air humidity, downward shortwave...

When I ran the case of the simulation of 165Ma with cesm-dt2.0, this error came and I haven't seen this before. So I want to know what the error is and how to solve it. Thx a lot :) and the below is my set in pop2

I have modified the POP2 source code before to write out variables only at select depths before and am trying the same for TEND_TEMP at the shallowest model level. My plan is to just create a new 2d variable. Here are the steps I have taken (steps 1 and 2 are from within passive_tracers.F90) 1...

Hi all, I'm running a coupled atmosphere-ocean compset in CESM2.2.0 on Cheyenne. I have successfully run this compset for 10 years - in the next run of 10 years it crashed at year 18. The error in the cesm.log is: WHL, oc_tavg_helper is already associated; reset the tavg fields 0: sysmem...

Hello everyone I am a new user of CESM/pop, and one doubt came to me when analyzing the ocean velocities output. Might be simple to answer, but I couldn't find the answer anywhere. I noticed U/V is separated into three components,e.g., for V = VVEL,VSUBM,VISOP. My question is: does VVEL already...

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)...

Hi, I am running CESM 1.2.1 using the G_INTERANNUAL compset. Forcings are from the CORE II data set (1949-2009, 62 years per cycle). When I use the f09_g16 grid, the AMOC seems fine. But when I repeat the above simulations using the f45g37 grid, AMOC seems to be pretty weak. I guess the...
