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...

Hi all, We're using CLM5 (in CESM2.2.0) in both SP and BGC-CROP modes and we're interested in calculating the methane emissions from wetlands. Is there a way we can scale grid-cell surface CH4 flux to the atmosphere to give a wetland CH4 flux? We tried scaling by land fraction and wetland...

What is the definition of the canopy bottom height in CLM 5.0? It seems to be unclear in the tech note. Is there a way (using somewhat function) to get the canopy bottom height data from the canopy top height data?

Hello everyone, I use release-cesm2.2.0 and try to get the outputs with 'GRAINC_TO_FOOD'. I run this case with CAM60+CLM%Bgc-Crop+initial file "b.e20.BHIST.f09_g17.20thC.297_01_v3.clm2.r.1979-01-01-00000.nc". Unfortunately, I encountered such error to stop the run. "lnd_import ERROR: Longwave...

Hi all, I am trying to run CLM-FATES. I intend to use 2015-2050 simulations. My case was set and modified as COMP= I2000Clm50Fates ./xmlchange RUN_TYPE=startup ./xmlchange RUN_STARTDATE=2015-01-01 ./xmlchange DATM_CLMNCEP_YR_START=2015 ./xmlchange DATM_CLMNCEP_YR_END=2050 ./xmlchange...

Hi everyone, I am relatively new when it comes to designing and running climate models, so I had a question or two on how CESM2 is coupled. I have tried to read a few papers and the user manuals but they were not very much help. I understand that all of the major components (CAM,CLM,etc) send...

Hi all, I'm running a coupled atmosphere-ocean compset in CESM2.2.0 on Cheyenne. I have successfully run this compset for 10 years - in the next run of 10 years it crashed at year 18. The error in the cesm.log is: WHL, oc_tavg_helper is already associated; reset the tavg fields 0: sysmem...

Hi all, I've been working with some PFT-level data from CLM5 (e.g. NPP for each PFT) and have been using Python code from the NCAR-ESDS documentation to do the processing (Sparse arrays and the CESM land model component — NCAR-ESDS 0.1 documentation). This worked great until this week and I am...

Hi, I would like to do a transient run of CESM2.2.0 over the period 2015-2100 using SSP3-7.0. I plan to use a transient land use change scenario in CLM5 ('flanduse_timeseries'). However, the namelist setting 'sim_year_range' in CLM5 only permits running over the period 2000-2100. As I'm not...

Hi all, I have done some runs with CLM5 in land-only mode and have a result I'm not sure how to explain. The runs are at 0.5deg resolution over a regional domain covering sub-Saharan Africa over the period 2015-2100. We have used SSP3 anomaly forcings and done runs with CO2 increase only, CO2 +...

Hello. I am trying to do a branch run from the CESM2 LENS data; however, the model stops when initializing the land component with the following error: Reading restart file b.e21.BHISTsmbb.f09_g17.LE2-1251.018.clm2.r.2015-01-01-00000.nc Reading restart dataset check_dim ERROR: mismatch of...

Hi, can I change the fsurdat from surfdata_0.9x1.25... to landuse.timeseries_0.9x1.25.... I tried changing it in CESM2.1.3 with ISSP370Clm50BgcCrop compset but encountered some problem: Default: fsurdat =...

Hi all, I'm working on change land-sea distribution in the CESM2.1.3, I have generate new ocean domain file and land domain file, and mapping files. The error happened in the run time, viewing the cesm log it says: ENDRUN: ERROR: ERROR in surfrdMod.F90 at line 384 ERROR: ERROR in...

Hi all, I'm working with the 1D PFT-level output for CLM5 for the first time. I am interested in plotting a timeseries of some PFT-level variables over my domain. I can see in the variable list that my history files contain a variable called 'pfts1d_wtgcell' (PFT weight relative to...

Hello CESM community, I am encountering one ERROR recently when I run a model with the following compset, turning on fire, compset: I2000Clm50BgcCru CLM_BLDNML_OPTS="-fire_emis" After creating the case, I made some changes in user_nl_clm, such as fire_emis_specifier = 'CB1 = 0.5*BC'...

Hi, every one! I study in spectral element variable model in CESM2.1.3 for a long time, when I try to use the script in ($CESM)/components/clm/tools/mkmapdata/mkmapdata.sh to create the clm input data (like the surfdata_xxx and the landuse_xxx), the procedure died when the following error...
