clm5.0

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.

Namaste from India, Myself Rakesh Vadnathani, PhD scholar (physics) from Ganpat University, India.I have chose subject related to soil, vegetation, atmosphere interactions. I have worked on GLDAS and FLDAS model data, solar data, upper atmospheric dynamics, siesmo-ionospheric interactions...

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 =...

Hi! I want to run preliminary CESM2 PI and LGM simulations to then use their climate/soil output to feed as input for BIOME4. The final objective is to feed PI- and LGM-equilibrated vegetation derived from BIOME4 to CLM5's dust emission scheme. BIOME4 requires gridded fields of 1) soil water...

Hi, all I set up a case using I2000 but with transient land cover (simulation time 1992-1996), firstly the surfdata and landcover.timseries are all from NCAR, it works well, but when I change it to the modified land cover data, i change surfdata and also landcover.timeseries and 99% confirm...

Hi, everyone. I'm trying to do some experiments based on the changes on the stem area index (SAI/Ls). I noticed that in the document of CLM5.0 the stem area index was described as ''Prescribed plant functional type (PFT) stem area index is derived from PFT leaf area index phenology combined with...

Hi, I want to manually increase the wall insulation in CLMU to assess its impact on the building's space heating and air conditioning fluxes. In the paper by Oleson and Feddema (2020) (https://doi.org/10.1029/2018MS001586), it is mentioned that "For high latitude locations, insulation was added...

Hi, all, I create a IHIST case with the simulation period from 1999-2001, but when I check the logfile, I find the Attempting to read pft dynamic landuse data ..... (GETFIL): attempting to find local file landuse.timeseries_0.9x1.25_hist_16pfts_Irrig_CMIP6_simyr1850-2015_c170824.nc...

Hi, I really don't know where I have a problem here, I just want to run an I2000CLM50CN model, so just do some basic Settings. ./xmlchange STOP_OPTION=nyears,STOP_N=170,NTASKS=164 ./case.setup ./case.build ./case.submit However, I never see the growth of vegetation. In the result, TOTSOMC only...

Hi, I tried to run I2000CLM50CN composet for ten model years without making any modifications. However, when I checked the output TLAI or GPP, I found that its value was normal in the first year, but it began to decline rapidly in the second year and approached 0. I understood that this meant...
