    soil type data

    Dear all, How can I get the input data for soil type (such as sand, silt, clay, et.al) in LUMIP (in experiment ID of hist-noLu,ssp370-ssp126Lu), CMIP (historical), and ScenarioMIP( ssp370). Thanks.

    How to run CESM1.2.1 with Data Land model (CLM_DLND)?

    Hi all, I want to prescribe land surface temperature to drive the model, just like prescribe the SST. Hence I first run a 2-years control F_2000 experiment to output cpl hist files (xx.cpl.ha2x.yy.mm.dd.nc and xx.cpl.hl2x.yy.mm.dd.nc) in so-called "DLND_CPLHIST_DIR". Then I used these cpl hist...

    Use external shortwave data in CESM2 coupler

    In my experiment, I want to hold the solar radiation using external data. So I plan to use downloaded shortwave (solar radiation) data to overide the model calculation sw value in CESM2 coupler. I found the coupler sw calculation process in subroutine seq_flux_ocnalb_mct in the file...

    addco2_user_nl_datm.user_nl is missing, how do I edit the user_nl_datm for a transcient CO2 PTCLM case?

    I'm not entirely sure if this should go in the CLM or DATM forums, so apologies if I've guessed wrong. I'm trying to run PTCLM5.0 with transcient atmospheric CO2 concentrations. As per this guide, these are the steps I have taken...

    Data products from an 80 member reanalysis using CAM6 and DART

    We have recently finished a 2011-2019 reanalysis using CAM6 and DART. Several data sets have been archived to the Research Data Archive 345.0. They are designed to be useful to a variety of researchers in the CESM community. We're interested to know whether you feel that this would be a...

    Error when excute mkmapdata.sh :unable to detect the source grid file type

    Dear Scientist, Recently I want to run a regional case (centerpoint is 114.1°E,30.4°N,grid number is 10×10, and the grid resolution is 0.1°×0.1° ) using CRUNCEP as forcing data and Jackson as surface datasets. However, there are two questions bothering me: 1. The correct step is using...

    How to create surface datasets in regional simulation using clm5.0

    Dear scientist, Recently I want to run a regional case using CRUNCEP as forcing data and Jackson as surface datasets. However, there are two questions bothering me. 1. The correct step is using mkscripgrid.ncl to create scripgrid file ,then using mkmapdata.sh to create mapping file, then...

    Running with your own atmosphere forcing

    Hi all, I am trying to run CLM5 using my own atmospheric forcing. I followed the guide on http://www.cesm.ucar.edu/models/cesm1.2/clm/models/lnd/clm/doc/UsersGuide/x12979.html but somethings still appear unclear. 1. the file link_dirtree does not seem to exist in my scripts directory 2. the...
