High-resolution hydraulic parameter maps for surface soils in tropical South America
Spatial data files holding gridded parameter maps of surface soil hydraulic parameters derived from a selection of pedotransfer functions. Modern land surface model simulations capture soil profile water movement through the use of soil hydraulics sub-models, but good hydraulic parameterisations are often lacking - especially in the tropics - and it is this lack that we fill here in the context of South America. Optimal hydraulic parameter values are given for the Brooks and Corey, Campbell, van Genuchten-Mualem and van Genuchten-Burdine soil hydraulic models, which are widely-used hydraulic sub-models in many land surface models (e.g. Joint UK Land Environment Simulator JULES).

Soil measurements have been interpolated from several sources including new and original data as well as older sources such as RADAMBRASIL http://daac.ornl.gov/LBA/guides/Pre_LBA_RADAMBrasil.html , using the polygons of the SOTERLAC soil and terrain database as a base (http://www.isric.org/projects/soter-latin-america-and-caribbean-soterlac ). All files were generated using Esri ArcGIS 10.0 at 15 arc-sec resolution (cells ~ 450 m x 450 m at the Equator) snapped to the HydroSHEDS Digital Elevation Model (http://www.hydrosheds.org/ ). All NetCDF files conform to the Climate and Forecast (CF) conventions. For more detail of all methods followed, please see Marthews et al. (2014).
