clm5.0

Dear Team, I am trying to add some forest cover and remove some shrub and grass cover in CLM5.0 in CESM2.1.2. Since I could not find it in the technical note for CLM, I wanted to ask here what the albedo and snow-masking properties of the shrub and grass PFTs are and how they differ. Thanks...

Hi all, I'm running CESM2.1.3 (CLM5.0) and am interested in outputting certain CLM5 variables to do with fire at PFT level. I set up two identical test cases, with the same input files, where one case specified PFT-level output and the other didn't. The latter case ran fine; the former case...

Dear Team, I want to run CESM2.1.2 (with CLM5.0) with additional forest cover in some regions. My aim is to use the forest cover of 2015 as a baseline and then afforest transiently until the end of 2100 under an SSP forcing. While I understand how I can adjust the PCT_CROP, PCT_NATVEG and...

Dear Team, I am using CLM5.0 with CESM2.1.2 and want to change a surfdata file to add additional tree cover. Thus, I wrote a python script where I am changing the PCT_CROP, PCT_NATVEG and PCT_NAT_PFT variables in the file surfdata_0.9x1.25_hist_78pfts_CMIP6_simyr2014_c200512.nc. However, I saw...

Dear all We are using the CLM5.0 model to conduct a series of parameter sensitivity experiments. But there are some questions in the process After we modify the parameters, do we need to restart the cold start to make the model reach a new equilibrium and stable state before the final spinup...

Dear all, I used CLM5.0 in CESM2.1.2 for single point simulation, and the simulated site was FR Pue (Puechabon, France) (43.7413, 3.5957) The time is from 2000 to 2014, and the vegetation type is evergreen broad-leaved forest. Atmospheric forcing data from half-hour observations at...

What version of the code are you using? ctsm5.2.023 Have you made any changes to files in the source tree? None Describe every step you took leading up to the problem: Typical steps for regional case: ./create_newcase --case...

Hello everyone, I am very new to CESM and CLM so this might be obvious for others but I could not find a direct answer online. Later on I would like to use the BGC-CROP mode alongside SSP245 input data in a fully-coupled set-up. To get more familiar with CESM2.1.2, I ran some test simulations...

Rush rush rush! Seeking help I want to create custom resolution surface data, first, I created a SCRIP grid file using ./mknoocnmap.pl -p 47.7333,88.0833 -dx 0.01 -dy 0.01 -n $GRIDNAME successfully but when I run mkmapdata.sh to create mapping files, I get an error: ERROR: Problem on processor...

I have been able to successfully build and submit a case using the F2000climo compset with clm5.0:Satellite phenology but am now running into issues trying to run an identical case just with clm5.0:BGC (vert. resol. CN and methane) with prognostic crop. In other words: I ran one experiment...

While running the clm5.0.35. The model setup and built has been successful. When I submit the case, it shows: PNETCDF not enabled in the build, The case compset is I2000Clm50FatesGs.

Hi there, I am currently conducting an experiment related to MUSICA, using CLM5.0 to create mapping data for surface data production from the file UGRID_1km-merge-10min_HYDRO1K-merge-nomask_c130402.nc. I have encountered an error related to memory reference. The computing node I am using...

Hi, everyone. I recently have got an idea that need to add a new module.F90 which written by myself to change the soil freezing and thawing process. But after I put the new .F90 file in src.clm/biogeophys/, Am I should seek the .F90 file contain the main program and change the calling...

I'm having some issues downloading input data. I am following this page to do a single point clm 5 run on cesm 2.1.5. I know support for specifying PTS_LAT/PTS_LON in create_newcase was dropped from cime at some point, but I can just change it after the case is created. # create the test...

Hi, all I set a ssp126 and ssp585 simulation for future. I have some confusions about the co2 difference about the ssp126 and ssp585 compset (with anomaly_forcing method). The compset longname is SSP126_DATM%GSWP3v1_CLM50%SP_SICE_SOCN_MOSART_SGLC_SWAV. The co2 difference can be found in...

Hi, everyone. I would like to carry out an experiment with prescribed climatology of soil moisture over the land. I set "use_soil_moisture_streams = .true. ". I think the prescribed soil moisture file will replace the model prognostically determining soil moisture. My question is how often does...

Hello,every. I am doing tests on black carbon aerosols, I have turned off the black carbon radiation fluxes in the CAM module, now I want to turn off the on-snow black carbon deposition fluxes , I don't know which switch to turn off in which file, any help would be appreciated!

I would like to (historical) model and (future) project responses of the Canadian permafrost thermal state to climate change on the coupled energy-water-carbon fluxes using the CLM model. For this purpose, which component set do you recommend to use? I have compiled the CLM model (support...

Hi, all, I usually run I2000 with f09_g17 globally, it works well. But now when i change the res from 1deg to f05_g17, the errors appears: alling /users/rxu/CESM/cime/src/components/data_comps_mct/datm/cime_config/buildnml File not found: domainfile =...
