    How to run a simulation with prescribed soil moisture using the F compset in CESM2.1.3?

    Dear all, I want to investigate the response of atmosphere to the variability of soil moisture over a certain region. I wonder how to modify the soil moisture and which files or setting should be changed. Any reply would be greatly appreciated.

    How can I use my CO2 data in the model(CLM5.0、CESM)?

    I want to create a case to make the model use my own downloaded co2 file (cmip6 download rcp2.6 data) : /home/hlh/cesm/inputdata/atm/datm7/CO2/fgco2_Oyr_CanESM5_rcp26 - cmip5_r1i1p1f1_gn_2006 - 2100.nc How can the next operation be completed? Hopefully, you can start by creating a case How...

    How to convert LUH2's landclasses to the landclasses needed by the CLM

    Hi,all! Recently I've been trying to use the new GCAM data to convert it into land use data that can be driven by CLM (related post). I still have some questions about how LUH2 is converted to CLM standard format for land use driver data. My CESM version is 2.1.3. 1. When converting to LUH2...

    Are there SSP scenarios that can be run with a small number of PFTs types now?

    Hi,all! my CESM version is 2.1.3.I wonder if CESM can have SSP scenarios that can be run with few landuse PFTs? The current SSP scenarios have a lot of land use categories set up, with 78 for CROP. Are there any SSP scenarios that can be run where the land types are not as detailed? (For...

    how to separate biogeological and biochemical effects by setting up the CESM components?

    Hi,all! I would like to know how to separate biogeological and biochemical effects by setting up the CESM components? I guess it is to turn off the cycling of the carbon and nitrogen pools in the CLM, does this mean I need to use CLM50%BGC (turn on the carbon and nitrogen pools) and CLM50%SP...

    Inconsistency between the number of land use types in the available data and the number of land use types in the CLM

    Hi,all! We have focused on the output of the GCAM model under future scenarios, but the land use types output in GCAM are mostly aggregated. For example, in CLM vegetation is classified into a total of 16 categories, but in the GCAM outputforest is only distinguished into 5 categories(AR6...

    Representing dynamic prognostic crops in CLM4.5

    What version of the code are you using? CESM1.2, CLM4.5 Have you made any changes to files in the source tree? Overwrite the error checks in clm_varctl.F90 and surfrdMod.F90 that arise due to the combined use of crop_prog and fpftdyn. Describe every step you took leading up to the problem: I...

    It doesn't work in changing surface data

    Hi all, I want to run two B1850 time series experiments use CESM 2.1.4, and I also changed the surface data in one of them, but it doesn't work (i.e., it outputs the same result as the CTR simulation). I ran two B1850 time series simulations: Control simulation: echo "flanduse_timeseries =...

    CLM initial field and version issues

    Hi, I've recently been exploring land-atmosphere interactions and would like to run the 2019 simulation with a more accurate land surface initial field. In the input data, the land surface initial field for the most recent year is clmi.BHIST.2010-01-01.0.9x1.25_gx1v7_simyr2010_c181015.nc. I'd...

    CLM version in CESM2.3

    Hi, When I use cesm2_3_beta17, I can choose CLM5.0, CLM5.1, or CLM6.0 for the land component. I’m wondering where to see their code difference, is it in the my_cesm_sandbox/components/clm/src directory or other places? Best, Zehui

    why the EFLX_LH_TOT do not equal to Qsoil +Qvege+QVEGT

    Hi, all I calculated the gap=ET/28.36-(qsoil+qve+qvt)*24*60*60 (unit: mm/d). But I have find most of the value of gap larger than 0 in vegetation regions. So, which method is accurate to get the ET from CLM, use the ET/28.36 or (qsoil+qve+qvt) ? Best Ru

    Issues downloading input data in clm5 single point mode

    I'm having some issues downloading input data. I am following this page to do a single point clm 5 run on cesm 2.1.5. I know support for specifying PTS_LAT/PTS_LON in create_newcase was dropped from cime at some point, but I can just change it after the case is created. # create the test...
