The Global Soil Wetness Project (GSWP) is an ongoing environmental modeling research activity of the Global Land-Atmosphere System Study (GLASS) and the International Satellite Land-Surface Climatology Project (ISLSCP), both contributing projects of the Global Energy and Water Cycle Experiment (GEWEX). Its goals are to:

  1. Produce state-of-the-art global data sets of land surface fluxes, state variables, and related hydrologic quantities.
  2. Develop and test large-scale validation, calibration, and assimilation techniques over land.
  3. Provide a large-scale validation and quality check of the ISLSCP data sets.
  4. Compare Land Surface Schemes (LSSs), and conduct sensitivity studies of specific parameterizations and forcings, which should aid future model and data set development.

GSWP-2 is closely linked to the ISLSCP Initiative II data effort, and LSS simulations in GSWP-2 will encompass the same core 10-year period as ISLSCP Initiative II (1986-1995).
