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...

Hi, I would like to know what variables can be output by running CLM5, and where can I find the information

Hello, I recently created a new case using the "ISSP126Clm50BgcCrop" compset in CESM2.2 to monitor the ISSP-based climate effect. "datm.streams.txt.Anomaly.Forcing.*" were not present in the case directory, so I added the following line to the user_nl_datm. anomaly_forcing =...

Hi all, I'm doing a regional CLM-only run over Africa with anomaly forcing from DATM. To run from 2015-2100 I separate the run into 17-year blocks and set RESUBMIT=4. The model runs fine for the initial set of 17 years and writes history files as expected. However, when the first resubmitted...

Hello, everyone. I am trying to write a new tracer to CLM BGC. I got a 2D global soil Hg concentration netcdf file. The workflow is I need to transfer the 2D conc. file into finidat 1D variable. But I cant find any tools in CLM tools or guidance about this workflow. Does anyone tried this...

Dear all, I am using CLM5. Spatial land surface heterogeneity in CLM is represented as a nested subgrid hierarchy in which grid cells are composed of multiple land units, snow/soil columns, and patches. I find that at most 79 types of patches are used in CLM5, including not_vegetated, trees and...

Hello, I have used this for my case: "./create_newcase --case /home/meisam/scratch/cases/feb07 --compset I1850Clm50Bgc --res f19_g16 --machine narval --walltime 00:10:00 --run-unsupported". the config_machine.xml, config_batch.xml, config_compiler.xml, and other related files to the...
