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).

- Statement
- 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).
