clm5.0

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 everyone, I would like to investigate the role of soil moisture in the influence of the Atlantic Multidecadal Variability (AMV) on the Eurasian climate. Therefore, I would like to design an experiment with prescribed postive-AMO SST pattern in Northern Atlantic and climatology of soil...

Hi, everyone, I have finished a simulation using FHIST for periods 1990-1994, i have checked the output of tempeature variable, There is TSKIN in clm and TS in atm, the TS is described as the radiation temperature，but the TSKIN is also the radiation tempeature? I am not sure their differnce, i...

Hi, I am trying to nudge soil moisture to climotology in F2000climo in CESM2. I only found the Nudging Experiment example (U, V, T, Q) in CAM6.3 User guide. How can I perform a Soil-moisture nudging experiment? I think this experiment should be based on the CLM%, but I haven't found any...

My machine is a centos7 supercomputer at NIES (Japan) with PBS batch sytem. I executed the following commands with all commands executed successfully without errors. ./create_newcase --case I1850CLM50_001 --res f19_g17 --compset I1850Clm50Sp --mach sx-aurora ./case.setup ./case.build After...

Hello, everyone. I been confused with the DATM setting we have been used in the hist or 1850 or 2000 compsets. The question is: does datm stream file will automatic align with the option of "RUN_STARDATE"? For example, if I set the RUN STARDATE = 2001, but the stream didn't change, then what...

Hello everyone, I am going to run a sim_year range without the datm7 data support by an "I" compset, such as the years like 1850-1860. Can I use the cmip6 historical experiment data as the datm input for the specific case? For example, the datm forcing data usually contains precipitation...

Hello everyone! Thank you for seeing my questions. My case is IHistClm50SpCru (HIST_DATM%CRUv7_CLM50%SP_SICE_SOCN_MOSART_CISM2%NOEVOLVE_SWAV). I want to research how the land cover type influnce the soil temperature, so I want to fix one type of PFT and compare it with default test. But the PFT...

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...

Hi, I like to use CMIP 6 projections in CLM5. My finding is that some of the data belonging to one scenario and from one global model may have inconsistent temporal resolutions. For example, precipitation can be 6 hourly, temperature 3 hourly, and incoming solar radiation hourly. Can I put files...

Hello, I have successfully run CTSM release-clm5.0 in CPLHIST mode in the past. When I apply the same methods to ctsm5.1.dev133, I get the following error for cpl files after submitting the case: Model datm missing file file730 =...

Hi,all. I changed the fsurdata of amazon area in the post. I run a control test using the default as F2000climo. the changed test using F2000climo,but I changed the fusrdata in amazon area. For the changed test, I spinup 50 years. And I continue to run 50 years. For the control test, i just...

Hi,all! I'm using F2000climo to simulate global changes from 2000-2050, I now want to output the 2000-2050 surface coverage dataset, what variables should I pick to output? Is it in the CLM component?

Dear all, I have doubt with the output variable "FSDS" in clm2.h0 files. From my perspective, FSDS means the downwelling shortwave raidation land received and FSDS = FSA (absorbed) + FSR (reflected). From biogeophys/BalanceCheckMod.F90, I know that fsa(p) + fsr(p) - (forc_solad(g,1) +...

fsurdat='/scratch01/csy/surfdata/surfdata_360x720cru_16pfts_Irrig_CMIP6_simyr2000_c170824.nc'(my new surfdata) hist_avgflag_pertape = 'A' hist_nhtfrq = -192 hist_mfilt = 1 hist_empty_htapes = .true hist_fincl1='TLAI' The 'TLAI' is a 2D array for the global LAI. But I need to output the LAI of...

Hi, I find it surprising that the same CESM2.2 CLM model output NetCDF file displays different "time" values when opened on different systems. Opening it using ncdump shows JANUARY: time:units = "days since 2015-01-01 00:00:00" while opening the same file by Python shows FEBRUARY...

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

Hi, While running the clm5.0.03. The model setup and built has been successful. When I submit the case, it shows the 'run command is mpirun -np 4 /home/clm/cesm/scratch/xinjiang_1/bld/cesm.exe >> cesm.log.$LID 2>&1 ERROR: RUN FAIL: Command 'mpirun -np 4...

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 =...
