cesm2

Hi everyone, I am still working to solve the issue as shown in the last thread(CESM2.1.4 case_run error: without any hist output nc files). I find there may be something wrong about the inputdata used in F2000climo because the cesm.log (also attached) says a lot of message as following...

Dear all, I recently ported CESM2.1.4 to our computer cluster, which has no internet connection. I tried running the F2000climo compset for the test. The case_create/case_setup/case_build/case_submit steps were finished successfully. However, I encountered an error during the case_run step: the...

Dear all, I am porting CESM2.1.4 on a cluster environment. I encountered problems during the case_build stage. The compiler is Intel mpi. I run the code as following: ./create_newcase --case runtestX --mach qhyc --compset X --res T42_T42 ./case.setup ./case.build Error occurred in the step...

Dear all, I would like to run a fully coupled simulation of CESM 2.1.3 for year 2000. As I did not find a "B2000" compset I created a case based on B1850. I tried to replace "1850" in the long name of B1850 with "2000", and run with the compset with longname...

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...

Hi everyone, I am using B1850 from CESM2.1.3. I want to export the daily SST received by CPL from POP. So, I set AVGHIST_OPTION=ndays and AVGHIST_N=1. With this setup, the model is able to successfully output o2xavg_So_t. However, the model also outputs a lot of variables that I don't need...

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...
