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...

Hi all, I'm trying to port CESM2.3.alpha17 to my HPC. When I run the ensemble test for F2000climo after installing the model: :/$CESMROOT/tools/statistical_ensemble_test> python ensemble.py --case $CESMROOT/runs/F2000climo_CESM2.3.alpha17.uf.0000 --ect cam --uf --mach archer2 --compset...

Hello, everyone! My compset is 1850_CAM60_CLM50%FATES_CICE_POP2%ECO_MOSART_CISM2%EVOLVE_WW3_BGC%BDRD conducted by CESM2, and all other settings are default. I want to analyze pattern changes in vegetation types, but I couldn't find related variables in the CLM output files. Does the default...

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...

Hi, all, I perform a simulation using IHIST, but accidently set the namelist as follow: &dynamic_subgrid do_transient_crops = .false. do_transient_pfts = .false. flanduse_timeseries =...

Hi, all, I plan to make a FHIST simulation using modified timeseries land cover data (time period 2000-2010) ,it means land cover in China needed to be changed annually, outside of china the land cover keep consistency as in flanduse_timeseries. Firstly, i change the value of PCT_CROP...

Hi, I want to add a section for soil decomposition, to determine how much carbon is decomposed due to the fire area, I made all the changes but it reported an error. do fc = 1,num_soilc c = filter_soilc(fc) f = farea_burned(c) i_s4s1 = 10...

I want to use the ICLMCN model to simulate soil carbon fluxes over historical periods, but there is no Component Set named 'IHISTCLM50CN', so how do I do this? My idea is to use I2000Clm50Cn to spinup the model for 600 years (to reach equilibrium)at first. Since IHISTCLM50CN does not exist...

Hi, Recently I have been trying to modify some of the CLM code to see the impact on the results. I was interested in soil carbon, so I tried to deal with the decomposition of soil carbon, and I did a simple test. Created a CASE - I2000Clm50Cn first, and then I copied...

Hi all, A fairly broad question but hopefully easy for those in the know - how would I go about estimating the water demand from natural PFTs (as opposed to crops)? I'm interested in comparing how much water is used by tree PFTs vs irrigated crops, domestic/industrial use, etc. for SSP...

Hi everyone, According to the CLM5.0 user's guide, If I want to create my own surface data, I need to first generate a SCRIPgrids based on the raw data, then use mkmapdata.sh to generate corresponding map files, and finally use mkserfdata_map generate surface daataset. What I want to know is, if...

Hi all, Hopefully an easy question for those in the know - which variable in MOSART (as implemented in CLM5) gives you the river basin area? The output files contain: areatotal basin upstream areatotal [m2] (global sum - 2.5 x 10^15 sq m) areatotal2 computed basin upstream areatotal...

Hi everyone, We plan to run CLM in the cloud and create a docker image for CLM. However, we observed that some efforts may have been made. Where can we find the most recent version (e.g., Dockerfile) so we do not have to reinvent the wheel?

Hello everyone! I am running CLM5 for a single point in my computer and I have read the guide 1.6.3.5. Example: Creating a surface dataset for a single point. When compile the "gen_domain", I used the following command: ../../../configure --macros-format Makefile --mpilib mpi-serial --machine...

Dear CESM land modeling community, We are seeking to archive hourly emissions from MEGAN 2.1 in CESM2.1.3 with CLM5. Using the standard outputs, we are seeing that we can get 10 different emissions (acetaldehyde, acetic acid, acetone, carene-3, ethanol, formaldehyde, isoprene, methanol...

Hi, I made some changes in user_nl_clm as: hist_fincl1 = 'FireComp_BC', 'FireMech_bc_a1', and so on other variables, but it seems it didn't find FireMech_. I can see 'FireMech_bc_a1' in the list in the link below, but why is it unable to find it? There is no problem with FireComp_BC, but only a...

Hi, I have recently conducted simulations using CLM5 in CESM2.2.0, and I am particularly concerned about the emissions from land fires. I compared several species using both the GFED4 and CMIP6 biomass-burning emissions files. While the emissions of all other species appear to match reasonably...

Dear all: When I compile 'mksurfdata_map', error occurs. (base) [zhangguanhao@master src]$ cd /home/zhangguanhao/CLM5/clm5.0/tools/mksurfdata_map/src (base) [zhangguanhao@master src]$ make make: /usr/local/lib/../bin/nf-config：Command not found ifort -ftz -g -fp-model precise -convert...
