This readme contains a full description of all required data for deriving the parameters and how to access each base dataset.

Required data inputs and their categories:

  1. Soils data: obtained from the ISRIC Global 1km soils data, http://isric.org/explore/soilgrids. Links below are for the 1km product, can also use 250m if higher resolution is desired, or coarser resolution (5km, 10km, etc). Relevant citation: Hengl T, de Jesus JM, MacMillan RA, Batjes NH, Heuvelink GBM, et al. (2014) SoilGrids1km - Global Soil Information Based on Automated Mapping. PLoS ONE 9(8):e105992. doi:10.1371/journal.pone.0105992
    1. organic matter: ftp://ftp.soilgrids.org/data/recent/OCSTHA_M_sd1_1km.tif (download for all 7 layers, e.g. sd1-7)
    2. coarse content: ftp://ftp.soilgrids.org/data/aggregated/1km/CRFVOL_M_sl1_1km_ll.tif (download for all 7 layers, e.g. sl1-7)
    3. silt content: ftp://ftp.soilgrids.org/data/aggregated/1km/SLTPPT_M_sl1_1km_ll.tif (download for all 7 layers, e.g. sl1-7)
    4. sand content: tp://ftp.soilgrids.org/data/aggregated/1km/SNDPPT_M_sl1_1km_ll.tif (download for all 7 layers, e.g. sl1-7)
    5. clay content: ftp://ftp.soilgrids.org/data/aggregated/1km/CLYPPT_M_sl1_1km_ll.tif (download for all 7 layers, e.g. sl1-7)
    6. bulk density: ftp://ftp.soilgrids.org/data/aggregated/1km/BLDFIE_M_sl1_1km_ll.tif (download for all 7 layers, e.g. sl1-7)
  2. LAI and Vegetation Height: 0.05-degree global product obtained from Peter Lawrence and Dave Lawrence at the Climate and Global Dynamics group, National Center for Atmospheric Research.
  3. Vegetation Classes (Plant Functional Types used in CLM): same source as for LAI and Vegetation Height, 0.05-degree global product
  4. Elevation data:
    1. GTOPO 0.05-deg elevation map, available through Oak Ridge National Lab (required EarthData registration for download): https://webmap.ornl.gov/ogc/dataset.jsp?dg_id=10003_1
  5. Climatological Temperature and Precipitation:
    1. WORLDCLIM 10-min data, 1970-2000, available here: http://worldclim.org/version2
  6. Hydroclimate classes:
    1. Brown et al 1997 permafrost map at 0.05-degree resolution, available via the Northern Circumpolar Soil Carbon Database (NCSCD), available at multiple resolutions (highest one and the one used for this process has been the 0.05-degree product) as NetCDF files and GeoTIFF files: https://bolin.su.se/data/ncscd/netcdf.php
    2. Koppen-Geiger global climate classes map, 0.05-degree resolution, available through Oak Ridge National Lab: https://webmap.ornl.gov/ogc/dataset.jsp?ds_id=10012
  7. Baseflow parameters:
    1. 1 degree global soil data, file is in this folder, titled: world.soil.parameter.txt
  8. GMT timezone information
    1. For now, please regrid this file, contained in the home directory: off_gmt_wr50a_vic5.0.dev_20160328.nc
