clm5

Hello Discuss CESM Community, I am clonning CLM 5.0 to my ubuntu-latest system. For which I have followed the below steps. 1st git clone -b release-clm5.0 GitHub - ESCOMP/CTSM: Community Terrestrial Systems Model (includes the Community Land Model of CESM) clm5.0 cd clm5.0...

Hello,everyone, I'm running CLM5-BGC with fire moudle, but I just run the default version. Actually, I want to change some parameters to make the simulation better or change some variable parameters to make a comparison experiment. What I mean is don't change the source code,just change some...

Hi! I am running the F2000climo compset with gird f19_f19_mg17 on HPC. After submission, the running stops when initializing the CLM component: cpl log: (seq_mct_drv) : Initialize each component: atm, lnd, rof, ocn, ice, glc, wav, esp, iac (component_init_cc:mct) : Initialize component atm...

Hi, I am using the surfdata file 'surfdata_1.9x2.5_16pfts_Irrig_CMIP6_simyr2000_c170824.nc' and have taken the weighted average of the 'monthly_lai' variable from the model’s default surfdata to compare it with GIMMS LAI data. In the CLM5 technical manual, I saw that the LAI values in the...

Dear Team, I am currently working on running CESM2.1.3 (cesm2.1.3-rc.01-0-g0596a97 with clm5.0.30) using landuse_timeseries, and I would like to compare this experiment with a control experiment where landuse_timeseries is not applied. Below are the details of the experiments; 1. Control...

Hi, everyone. I set use_soil_moisture_streams = .true. in user_nl_clm. I also set stream_fldfilename_soilm = '/BIGDATA2/fudan_zuozhy_3/cesm2.0/importdata/LFMIP-pdLC-SST.H2OSOI.0.9x1.25.20levsoi.natveg.1980-2014.MONS_climo.c190716.nc'. I note that the H2OSOI in the file...

What version of the code are you using? ctsm5.2.023 Have you made any changes to files in the source tree? Not yet. But looking to increase soil layer structure (either layer thickness or number of layers). Describe your problem or question: In src/main/initVerticalMod.F90, soil layers in each...

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...

Hi, I designed a experiment (startup run, F2000climo in CESM2) in which the soil moisture is prescribed with a given soil moisture climatology file. To reach this purpose, I set use_soil_moisture_streams = .true. in user_nl_clm. I also set stream_fldfilename_soilm =...

Hi, SOILLIQ and H2OSOI both reprsent the soil moisture. I would like to convert SOILLIQ (kg/m^2) to H2OSOI (m^3/m^3), which have different units. But I have no idea how to do. I am looking forward to any suggestions. Thanks in advance. Best, Kaiwen

Hello CLM community, I’m curious whether the I2000 compsets (such as I2000Clm50BgcCropGs and I2000Clm50Sp) average atmospheric/climate conditions over multiple years, -or if they rely on climate data specific to the year 2000. We need to evaluate the model outputs against ERA5-Land data, so...

Hi, I am trying to replace the soil moisture data with a soil moisture data climatology file in the fully coupled CESM1 or CESM2 (CESM1 is better) only when the model is calculating the heat flux (i.e., latent and sensible heat flux), and maintain the coupling state between the land and the...

Hi all, I'm seeing some odd behaviour using anomaly forcing with CLM5. I'm trying to run the compset ISSP245Clm50BgcCrop in CESM2.1.3. I create the case and add the following to user_nl_datm: anomaly_forcing = 'Anomaly.Forcing.Precip', 'Anomaly.Forcing.Temperature', 'Anomaly.Forcing.Pressure'...

Hi all, I am doing some simulation experiments by changing PFT fractions to representing vegetation changes. I run simulations for 90 years with CESM2.1.2 ETEST(2000_CAM60_CLM50%SP_CICE_DOCN%SOM_MOSART_SGLC_SWAV_TEST) compset and with f19_g17 resolution. ./create_newcase --case ETEST_oldsurf...

Hi all, I'm using CESM2.2.0 on Derecho and I want to make some land use data. To do this I need to use the built-in tool at components/clm/tools/mksurfdata_map, which I used before on Cheyenne. When I try to compile the code following the first step of the readme: cd src gmake I get a load of...

I have observed a stark contrast in irrigation coverage (mostly in the northern hemisphere) between cesm2.2.2 and ctsm5.2 CLM runs with identical case setup. Both runs used I2000Clm50BgcCrop compset and were simulated for 12 months starting 2000-01-01. Similar issue in all three irrigation...

Hi all, I'm trying to reproduce some CLM5 input files I generated on Cheyenne a while back, using the mksrfdata_map tool. For consistency reasons I need to use the historical files from CLM5.0 rather than the newer CTSM5.2 ones which have different land use. The filenames are...

Hi all, I have a transient historical run in CLM5 starting in 1901 which fails after the first few timesteps or so. The error in the atm.log is (shr_dmodel_readstrm) file ub...
