Hello everyone, my CESM version is 1.2.2. I want to modify SST boundry data to discover observational SST's(from 1979-2021) impact on atmospheric variability. To achieve this goal, i use FAMIPC5 compset to simulate the period of 1979-2021 and modify user_nl_cam to the same emission...

Hello everyone ,"Does anyone know what parameters in user_nl_clm can be adjusted to change the simulation of soil moisture and soil temperature?"

Hi,all, I am porting my model (CLM5 )from a gcc compiler platform to derecho, it works well with gcc compiler. but derecho seems only has default intel compiler, as I did not find any gcc tag in config_compiler.xml and config_machine.xml for derecho. Is there anyone can share how to use gcc...

Hi,everyone！ I have recently generated land use data for the years 2015–2100. My data format is similar to LUH2, but the land unit in my data represents the area (in square kilometers) of different land types within each grid cell. My land use data includes seven plant functional types (PFTs)...

Hi everyone, I am doing some studies about ozone-vegetation feedback. And the ozone can damage the vegetation's stomatal conductance. I have seen the source code in the `PhotosynthesisMod.F90` file. The ozone damage factor for stomatal conductance (`o3coefg`) only affects `rs_z` (resistance)...

Hi, I want to run a simulation for 1980-2020 using the compset FHIST, but the model stopped when it reached 2015. I checked the log file, and the error shown is: ERROR: GETEIL: FAILED to get Inputdata/atm/cam/strataero/ ozone_strataero_WACCM_L70_zm5day_18500101-20150103_CMIP6ensAvg_c180924.nc...

What version of the code are you using? CESM2.1.5 Have you made any changes to files in the source tree? Not yet Describe your problem or question: Dear community, I plan to run a set of nudging experiments based on compset FHIST_BGC in CESM2.1.5. However, instead of using the default...

I want to use a LAI with interannual variability (1980-2020) in the model. From previous posts, I roughly understand that lai_streams can be used to achieve this, but I still have some doubts that I hope you can help me clarify. The compset I am using is FHIST...

Dear colleagues I am running CLM5 in a 3 km resolution regionally over the EU-CORDEX domain. Thus far, our model worked with forcings that we downscaled to this 3km EU-CORDEX grid without problems. Now, I need to run the same clm5 model but with 12 km resolved forcings (over the same domain). I...

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 =...
