LDAS specific VIC input files
The database developed for the LDAS VIC long-term simulations includes a complete 53 column VIC soil file (VIC version 4.0 with 3 soil layers) in the file soil_ldas.txt covering the entire LDAS domain. The program create_LDAS_soil.c takes as input the name of this LDAS soil file and a list (2 columns) of the latitudes and longitudes of the 1/8 degree cells of interest. The resulting soil file is complete, with the exception of the following, which are determined during calibration: Ds, Dsmax, Ws, b_infilt, soil_depth (each layer); and the columns for annual average precipitation and temperature, which are generated from the meteorological data. Download database and code here.
With an ascii/column type soil file developed as described above, a program, create_LDAS_veg_param.c, has been developed to extract a vegetation parameter file from a vegetation parameter database to match the soil file. This program, along with the database, is part of the compressed tar file LDAS_prep.tgz, also available under the "Preparing VIC Model Inputs" section of the download page.
