I am new to CLM and have been successful until the case.setup step following Creating-and-Running-a-CESM-Model/CLM5.0 Tutorial--Creating and Running a CESM Model.docx at master · cwsauburn/Creating-and-Running-a-CESM-Model I wanted to know from where to download the input data for the model.
I have several questions about soil layer structure in CLM4.5 and CLM5.0
(1) Why soil layer structure is non-linear in CLM4.5 and CLM5.0? Why is the difference between the two version?
(2) Running CLM4.5 or CLM5.0 over a single-point, observations at 5, 10, 20, 40cm were...
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...
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...
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...
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’...

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：

When I started using commands/ case.submit
The following error occurred:

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：
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"
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 .
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.
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.
