Global Soil Wetness Project (GSWP)
Entry ID: GSWP

[ Update this Record ]

Summary
Abstract: The Global Soil Wetness Project (GSWP) estimates global soil water by
using miscellaneous land surface process model and atmospheric data.

GSWP is an ongoing modeling activity of the International Satellite
Land-Surface Climatology Project (ISLSCP), a contributing project of
the Global Energy and Water Cycle Experiment (GEWEX). The GSWP is
charged with producing a 2-year global data set of soil moisture,
temperature, runoff, and surface fluxes by integrating one-way
uncoupled land surface process models (LSPs) using externally
specified surface forcings and standardized soil and vegetation
distributions, namely, the ISLSCP Initiative I CD-ROM data
("http://daac.gsfc.nasa.gov/")
Approximately one dozen participating LSP groups in five nations have
taken the common ISLSCP forcing data to execute their state-of-the-art
models over the 1987-1988 period to generate global data sets.
