cesm2

Hello Folks, I’m wondering whether someone has an idea about the data availability of CESM2 output meteorological data (e.g., air temperature, precipitation, radiation, wind, pressure, etc.) at 3- or 6-hourly time step from CMIP6 project. I have checked the Earth System Grid Federation (cmip6 -...

I have created a CIME case, which has been setup and built. As I understand, the namelist files user_nl_xxxx can be edited post-build. If I want to vary a namelist setting X across several runs, I can do that by 1) Running CESM 2) editing X=... in user_nl_xxxx 3) Run again Two problems... 1)...

Hello. I'm a novice in CESM2.1.3 and I learned a lot after reading the user's guide.Recently, I have some problems in running model. I want to run the coupling test of CMIP6, and then modify the parameters for sensitivity test. So, I did the following. At first, ./create_newcase --case...

Hi , I am still trying to port CESM2 to my university HPC. There is no errors wehen I executed ./case.build. After I executing ./case.submit, error pops up (shown below): **************************************************************************************************************************...

I was following the instructions on 1. Introduction — CIME master documentation. > cd cime/scripts > ./create_newcase --case mycase --compset X --res f19_g16 > cd mycase > ./case.setup First I execute ./create_newcase, everything works. I get: 【 cesm model version found: release-cesm2.0.1...

Previously, I have used scientifically validated CESM2 case "b.e21.B1850.f09_g17.CMIP6-piControl.001" for my research that was located in this directory: /glade/collections/cdg/timeseries-cmip6/b.e21.B1850.f09_g17.CMIP6-piControl.001 Recently, this case has been removed. The CESM2 website also...

my cesm version is 2.1.3. I'm running the test case post on CESM2 quick start guide (b.e20.B1850.f19_g17.test --compset B1850 --res f19_g17). I download the inputdata manually because of the low script download speed. when I running the ./case.build part, some errors have occurred...

Hi all, I am going to run a test in a local cluster where we have CESM2. These are the steps that I follow: create_newcase --compset FWmadSD --res f09_f09_mg17 --case=~/cases/test cd ~/cases/test/ ./case.setup ./case.build build step goes well and successfully finished the job. Then...

Dear all， Now , I am porting cesm2.1.1 to centos6, however there was some trouble: I use the command as follows: (1) ./create_newcase --case test_case --res f19_g17 --compset B1850 --mach majun (2) ./case.setup (3)./case.build error occurs in the step "./case.build", it shows: ERROR: BUILD...

Dear all, Recently, when I was porting cesm2.0.0 to centos6, I use the command as follows: (1) ./create_newcase --case test_case --res f19_g16 --compset X --mach majun (2) ./case.setup (3)./case.build error occurs in the step "./case.build", it shows: ERROR: BUILD FAIL: xatm.buildlib...

Hi there,I am trying to run CESM2 on our super computer. I use intel/2017.u2 compiler. I get the following job process messages in $CaseStatus when I am trying to validate a CESM port with prognostic components in http://esmci.github.io/cime/users_guide/porting-cime.html by running...

Affected release and development versions: CESM2.y.z There is a known issue with Github's SVN-bridge software and SVN v1.11 as mentioned here https://subversion.apache.org/docs/release-notes/1.11#issues.Until that issue is resolved, you must use SVN 1.10.x or older. 

In CESM2.0.z: In transient cases without prognostic crops, %crop stays fixed at 1850 values, rather than changing each year. This affects CLM45 and CLM50 transient compsets without 'Crop' in their name; specifically the following (compsets in bold are ones that were listed as scientifically...

Affected Release CESM2.0.0 There is a problem with the ocean domain files when running a SCAM compset using the CESM2.0.0 release. Complete details about the problem and the tested fix are available at this github link: https://github.com/ESMCI/cime/pull/2736

Affected release: CESM2.0.0Affected machine: cheyenne.ucar.eduThere is a known problem with launching MPI jobs on cheyenne such that the user may be required to resubmit the model using the case.submit script repeatedly before the model run is launched successfully. The problem will produce...
