    Questions about clm50cn!!

    Hi, I really don't know where I have a problem here, I just want to run an I2000CLM50CN model, so just do some basic Settings. ./xmlchange STOP_OPTION=nyears,STOP_N=170,NTASKS=164 ./case.setup ./case.build ./case.submit However, I never see the growth of vegetation. In the result, TOTSOMC only...

    default root zone depth of the CESM

    Hello, I'm a new user and want to use the output of the CESM with the CLM5. I just have a simple question about the variable 'BTRAN2', which is the root zone soil wetness factor. I just want to confirm the depth of the root zone in the CESM is 0-0.5m(as written in Lawrence et al. 2019 or...

    Unable to successfully build the case

    Hi, I want to add a section for soil decomposition, to determine how much carbon is decomposed due to the fire area, I made all the changes but it reported an error. do fc = 1,num_soilc c = filter_soilc(fc) f = farea_burned(c) i_s4s1 = 10...

    I have model CESM model output "OC" and "SOA", does this OC refer to primary organic carbon (POC)?

    Hi, CESM community, I just want to be clear about the model output so as to clearly interpret my model results. I have "OC", and "SOA" in my model output. Are these OC and SOA completely isolated? OC refers to primary organic aerosol (POA), and SOA refers to Secondary organic aerosol. This is...

    How to reproduce identical output?

    I have been conducting a 150-year emission-driven simulation using CESM2. Unfortunately, I lost several decades' worth of data from the early period. I attempted to restore the data by using the original bld file and re-running the model, which led to the reproduction of the same output. I am...

    Differences Between CLM release-clm5.0.35 and release-cesm2.2.01

    I ran a 60 member ensemble spin-up using CESM w/ CLM release-cesm2.2.01 for the land component using the I2000Clm50BgcCrop compset and CAM4 atmospheric forcing's and the same was run using CTSM w/ CLM release-clm5.0.35. All of the following settings were the same between the two: Number of...

    How to turn ON fire in CESM?

    Hi, I am using CESM2.1.3 FMOZ compset. I tried turning on fire (./xmlchange --append CLM_BLDNML_OPTS=" -fire_emis"), but it always ended with an error message within a minute of job run. ERROR: fire_emissions_init: not able to map bc_a1 to chem species/forcing I have also posted this in another...

    "ice_ic" when replacing SST and sea_ice

    Dear all, I am trying to run a "F2000climo" compset using CESM2.1.3 and I want to replace the climatology SST and sea-ice with other data. Also I want to force the atmospheric component with SST & sea-ice in different year. Now, I have successfully modified the input data. I have changed the...

    Strange Error in CESM2 run: Error in input files

    Dear Sir/Madam, Hello! I am trying to use the PORT (Parallel Offline Radiative Transfer model) aiming to get the radiative forcing, following the instructions from Example: Using PORT to study flux differences due to 2 x CO2. I successfully passed the ./case.setup and ./case.build (with the...

    Why are FDS and FDSC constantly zero?

    Hi community, we are using CESM2.1.2 and CAM6 to produce 3 hourly output. Everything looks reasonable except Shortwave downward flux FDS and Shortwave clear-sky downward flux FDSC which are both zero at all timesteps and all locations. I am very new to the model but the run was started by...
