clm5.0

Hi， i'm a new user of clm5.0. I have several questions (1) I see the Global Attributes in the output xx.nc file showing: title = 'CLM History file information' comment = 'NOTE: None of the variables...

Hi, I am running CESM2.1.3 with FMOZ compset, trying to see the impact of landcover change. I keep on changing "PCT_NAT_PFT", "PCT_NAT_PFT+PCT_CFT" and "PCT_NAT_PFT+PCT_CFT+PCT_CROP". Making change on the first two runs well, but when I change PCT_CROP along with PCT_NAT_PFT & PCT_CFT, there is...

Hi, I want to validate the CLM5.0 output LST with that of MODIS LST(MOD11A1), I know MODIS LST is skin temperature, so should I use the variable 'TSKIN' of CLM output to compare? I just see there are three kinds of temperature(i.e., TSKIN, TG and TV) in clm5.0 output, however there is...

Dear staff, I only run CLM5.0 and build it successfully. However, when I ./case.submit, error in cesm.log shows； ERROR: component_mod:check_fields NaN found in ATM instance: 1 field Sa_u 1d global index: 398. The atmospheric forcing dataset I'm using is CLDAS, and using ‘CLMGSWP3v1’...

When I run ./mksurfdata.pl -r usrspec -hirespft -usr_gname 0.05x0.05 -usr_gdate 210328 to make surface map at 0.05 degree, there exist an error below ------------------------------------- Attempting to make Topography statistics..... domain_read_dims_1d read 1-d length from num_pixels...

I am using CTSM (Version ctsm1.0.dev084-306-gb146c62) to model Europe on a 3km grid with CLM5-BGC. I had regrid the domain and surface files created by the supplied gen_domain and mksurfdata.pl to fit the required 3 km grid. Because i read in some posts that it is not possible for CLM to model...

Hello, I am configuring a transient climate simulation using BSSP585 compset. I need to spin up my simulation before I ran my simulation from 2015-2100, because I modified the surface data and assigned individual soil column to each pfts. I think the spin up could be done by creating a...

I created the case:./create_newcase --case sp_clm_serial --res f19_g17 --compset I2000Clm50SpGs --mach homebrew --run-unsupported But when I'm using commands：./case.submit The following error occurred： [root@localhost sp_clm_serial]# sudo ./case.submit Creating component namelists Calling...

When I started using commands/ case.submit The following error occurred: Client protocol gftp not enabled Using protocol wget with user anonymous and passwd user@example.edu Could not connect to repo 'ftp://ftp.cgd.ucar.edu/cesm/inputdata' This is most likely either a proxy, or network issue ...

I have successfully created the case：./create_newcase --case case1 --compset I2000Clm50SpGs --res f09_g17 --mach homebrew --run-unsupported But my computer can't be used ./case.submit I choose to use instructions：miexec -n 2 ./cesm.exe But I encountered the following errors： [root@localhost...

当我在终端中键入：mpiexec -n 2 ./cesm.exe。发生以下错误：

我在输入/ case.submit的过程中第一次接触到CLM系统，总数将出现以下错误，希望得到大家的帮助，谢谢！

Hi, I prepared a 2020 urban raw data with 0.05 deg resolution and I would like to generate a 2020 surface data based on SSP5RCP8.5. Here are the steps I took in mksurfdata_map tool: Generate namelist: ./mksurfdata.pl -res 0.9x1.25 -no-crop -years 2010 -debug --ssp_rcp "SSP5-8.5" In the...

Hi guys~ I am using "CLM5.0_BGCcrop" to simulate the NEE of the crop( irrigation and rotation) . There is a difference between the simulated value and the measured value. Should I modify the phenology(e.g. CNPhenologyMod.F90) of rotation crop to improve the simulation accuracy . Looking forward...

Dear scientist, I can run a regional case using GSWP3 as atmosphere forcing in clm5.0. Recently, I want to replace the default GSWP3 with my own atmosphere forcing( named CMFD, 700x400, 3hr, 0.1°). Now the CMFD data has been processed to a single file to meet the requirements of the clm...

Hi, I ran a CLM5 simulation using I2000Clm50SpGs compset with 25km resolution. I am wondering if we can calculate the effective emissivity of urban and rural area from model radiation and temperature output? For example, I tried to calculate emissivity by Stefan-Boltzmann equation using emitted...

Now I can create regular(rectangle) surface datasets using some scripts attached with clm5.0 (e.g.mknoocnmap.pl, mkmapdata.sh gen_domain etc.), however my study region is irregular, what should I do to ? Is there any instructions to follow? Any suggestion or help is highly appreciated.

Dear scientist, Now I can successfully run clm5.0 at regional scale and 0.05° spatial resolution. However, it costs lots of time to run. I want it faster but don't konw how to set. The situtaion of my server is as follows: Logical CPU Number: 24 Physical CPU Number: 2 CPU Core Number: 6...

Dear all, recently, I am working on CAM6 with variable-resolution simulation. I want to run the simulation with FHIST_BGC component set. I build the model and can successfully complete the the simulation for 5 days (STOP_N=5). However, the model always crash when I change the STOP_N to a longer...
