cesm1.2

Hi everyone, I just wondering if there is a posibility to run the CESM model backward in time? I thought it would be an interesting techs to attribute the reasons for a certain phenomenon. I would appreciate it if anyone konw how to do it or want to discuss it. Best.

Hello, I am using CESM1.2.0 and recently started a piControl run using the B1850C5 compset (CAM5). I am wondering if this compset starts from a model state that has already been spun-up. If not, does anyone know if restart files for an equivalent piControl run are available for download...

Hello, When I built the CESM1.2. model via the command "./*.build", an error like icc doesn't exist occured as follows: " /iCESM1_2_0_1_geotrace_n02/models/utils/mct/configure: line 2347: icc: command not found configure:2356: $? = 127" But, actually icc exits on derecho...

I'm currently trying to build CESM 1.2.0. The idea is to port a previous project to a new HPC cluster. This compilation protocol has been used for multiple years on different clusters. I discovered however that this compilation process, specifically for the pio library, relied on a hardcoded...

I have encountered the following problem. How should I solve it： cp: cannot stat 'Makefile.conf.old': No such file or directory cp: cannot stat 'Makefile.conf': No such file or directory Makefile:4: Makefile.conf: No such file or directory gmake: *** No rule to make target 'Makefile.conf'. Stop.

Hello, everyone！Thanks for opening this thread. I need your help. I am running fully coupled climate simulation (use B1850 compesite) with CESM1.2. The model has been running successfully for 3000 years.When I change to 'branch' continue to run the next, running successfully for six months and...

Hello, everyone! We’re going to run a case with SST increases by 6K uniformly (or even 8K) where there is no sea ice. However, it was successfully built but failed to run. We are using CESM1_2_1 and the composite is FC5 (air-land coupled). ****Note that we tried following methods but still...

Hello, everyone! We tried to raise the SST by 6K by using CESM1.2.1, but it failed to run. (We also tried 8K, but we met the similar error.) The configuration is CAM5 with CLM4 (FC5), grid is ~1 degree. The output of the debug are as follows...

Hi, When I use the iCESM1.2, I want to know is it possible to get reevaporation data? (The amount of liquid water in the cloud evaporating or ice sublimating into gaseous water) . Can I simulate it? And, if I want to simulate water vapor markers in future scenarios and use F-CASE, what do I...

Hi, When I run the iCESM1.2, I was puzzled by its' results. First I ran a simulation of iCESM.1.2 from 1975 to 2005(FAMIPC5CN), but something went wrong with the machine, and I only got the result from 1995 to 1998. So I ran a new simulation from 1995 to 2005, and want to make the results...

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...

After the recently system update on Cori, I can’t build the CESM1.2 on NERSC Cori any more. It gives the error message below: Load a valid targeting module or set CRAY_CPU_TARGET ccsm_comp_mod.o: in function `ccsm_comp_mod_mp_ccsm_run_': ccsm_comp_mod.F90:(.text+0x28): relocation truncated to...

Dear CESM community, My colleague and I are trying to perform some simulations using CESM1.2.2 that modify SW and LW at different layers. For example, we want to modify the model to reflect more SW upward or reduce the outgoing longwave at the atmospheric layer near the tropopause. I checked...

Hello, everyone! I am trying to port CESM1.2.1 to my personal computer: <OS>LINUX</OS> (Ubuntu 20.04) <COMPILERS>intel</COMPILERS> However, when I created a new case, some errors occurred. I ran the following command: And here is the error: I tried to change different machines and define my...

Hello everyone, I want to ask about how to run CESM with finer timesteps (for example, with STOP_N choice is 6h), the CESM version I use is CESM 1.2.1. I understand the CESM 1.2.1 is out of support for a long time, but this is latest version DART(data assimilation research testbed) can...

How do I turn on DVCN mode in the F case？when I set CLM_CONFIG_OPTS= bgc cndv it makes mistakes

plantform: centOS 7 CESM version: 1_2_1 compiler: ifort icc MPI: mpich In the scripts folder, I ran the following command: to create a simple case. Then in the case folder, I ran the following command: There is an error: The ConfigCase.pm line 448 is: foreach my $model qw(COMP_ATM COMP_LND...

Hello! I am processing climate data produced by CESM1.2 / CAM4. My goal is to provide visualizations of the top-of-atmosphere radiation budget to assess the impact of localized surface albedo modification. I am an intern who is new to CESM, and my question is very simple. Where are the model...

Hi all, I'm running CESM1.2.2 with CAM4. I wish to output 3D monthly averages of transient-eddy fluxes in the atmosphere (water vapor, temperature, geopotential, momentum). Are these fluxes available as standard History Fields? I had a look in the CAM4 documnetnation but couldn't find them... If...
