What version of the code are you using? CESM2.2.2 in Derecho Have you made any changes to files in the source tree? Some modification in nudging module Describe your problem or question: What and where is located the subroutine that generates all the log files?.. Thanks

Hi everyone, I plan to design a set of experiments using the B1850 compset in CESM2.1.3 to investigate the wildfire. My question is: do I need to make some necessary settings to activate the wildfire simulation? Looking forward to get any useful information. Best regards, KW

Dear all, I am doing a a set of experiments using the B2000_CAM5_CN compset in CESM1.2.2. The simulation seems successful, but the simulated years / cmp-day in cpl.log is negative (see the figure below). I'm concerned about the reliability of the simulated data. The mode run script is attached...

Hi everyone, I plan to design a set of experiments using the B1850_CAM5_CN compset in CESM1.2.2. I got this spun-up restart file b.e11.B1850C5CN.f19_g16.0850cntl.001 from - Revision 70334: /trunk/inputdata/ccsm4_init/b.e11.B1850C5CN.f19_g16.0850cntl.001/0850-01-01. When I restart the model from...

Hi all, I have a simple question: How can I calculate carbon emissions from vegetation fires? For example, in CMIP6, there is a variable called fVegFire, which represents the carbon mass flux from vegetation into the atmosphere due to CO2 emissions from all fires. However, I couldn't find the...

Hello, I have been trying to separate biophysical and biochemical effects using different components in CLM under the SSP126 scenario.My CESM version is 2.1.3 and CLM version is CLM5. I attempted to change the long name of BSSP126 in CESM from BGC to SP and link my own generated landtimeseries...

I plan to design a set of experiments using the B1850_CAM5_CN compset in CESM1.2.2. I got this spun-up restart file b.e11.B1850C5CN.f09_g16.005.rest.0501-01-01-00000.tar from the Globus endpoint. The experiment design is as follows: 1. Experiment 1: Restart the model from the above restart file...

What version of the code are you using? - cesm2_3_beta17_gui Have you made any changes to files in the source tree? - No Describe every step you took leading up to the problem: - port CESM model to perlmutter - modify config_machines.xml, config_compilers.xml, config_batch.xml, (gnu...

What version of the code are you using? CESM version: cesm2_3_beta17_GUI Have you made any changes to files in the source tree? No source code modifications Describe every step you took leading up to the problem: Modified config_batch.xml, config_compilers.xml, config_machines.xml with GNU...

When I was compiling cesm FCfireHISTcase, an error occurred. Now I'm not sure what caused these variables to be undefined. Was there a problem with my mpich compilation or something else? I tried to compile gpTL-8.0.3 by myself using mpicc and mpifort, but in the generated lgptl.a link, there...

Hi all, Some colleagues and I successfully ported CESM2.2.2 to the UK HPC service ARCHER2 a while back. I've just returned to using it and can build and run cases, however each case fails with the same mysterious error regardless of compset and other settings. In the cesm.log, we find: Abort...

I try to fully remove the seasonal cycle for an uncoupled run. I know how to do that for SST by pointing to a new SST file. In practice, I must hand‐edit dozens of files (atmosphere, land, aerosols, radiations, etc.) to replace them with constant fields. And I felt this way to be error‐prone...

I'm currently working on replicating the CESM2 Pacific Pacemaker Ensemble and am attempting to download the example POP grid definition file and the Python script used to generate the mask (in Step 1). When I click the provided link, I receive the following: Unauthorized: This server could not...

Hello, CESM team! Recently I started BSSP126 runs with my own landtimeseries data.I checked the sum of PCT_NAT_PFT is 100, also the sum of PCT_CFT. However, my simulations stopped in 2026 with the error message as below. My version is release-2.1.3, and the resolution is 0.9x1.25. I...

Hello, Since some CESM2 variables (e.g., ta, ua, va) have data missing for table_id = Amon and expt = hist_aer, would it be okay for me to calculate the monthly means from the daily data and use that (since daily data is available), or is that incorrect? I am using monthly data for these...

I looked at a run's prescribed SST anomalies and model output TS anomalies (ocean grids only). I noticed that they are different; the structures are largely the same, but the values have hemispheric shifts compared to the prescribed SST anomalies. I'm aware that there's a diddling procedure for...

Hello. I am using CESM 2.1.5 and am having difficulty getting cesm.exe to run as ported to my machine. I have not made any code changes or namelist changes. I created the case with: ./create_newcase --case f2000climo_testcase --compset F2000climo --res f09_f09_mg17 --mach lake I have set...

Dear managers As mentioned above.im try to transplant cesm on a arm64 system. So im using GNU compiler rather than intel. My CESM version is 2.2.0 Before make the case, i modified xml file in machines eg. config_machines.xml config_batch.xml config_compilers.xml (.xml was transfered to .txt for...
