Objective

Scripts to create ELM/CLM surface dataset and domain NetCDF files for a list of user-specified grid cells. The scripts create new datasets by extracting nearest neighbor data from existing global datasets. The generated surface dataset and domain files are in the unstructured-grid format.

Running the code

1. Download the code

git clone https://github.com/bishtgautam/matlab-script-for-clm-sparse-grid

2. Download surface data and domain data to run the 82x1_sparse_grid example

mkdir clm-netcdf
svn export https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/share/domains/domain.clm/domain.lnd.fv1.9x2.5_USGS.110713.nc ./clm-netcdf
svn export https://svn-ccsm-inputdata.cgd.ucar.edu/trunk/inputdata/lnd/clm2/surfdata_map/surfdata_1.9x2.5_simyr2000_c141219.nc ./clm-netcdf

3. Launch MATLAB

<MATLAB_INSTALLATION_DIR>/bin/matlab -nodesktop

4. Run the example

>> cd <matlab-script-for-clm-sparse-grid>
>> CLM45SparseGridDriver('82x1_sparse_grid/82x1_sparse_grid.cfg');
