What is SGP97?

The Southern Great Plains 1997 (SGP97) Hydrology Experiment took place in the subhumid environment in Oklahoma over a one-month period of June 18 - July 17, 1997. The objectives are:

1. To examine the estimation of surface soil moisture and temperature using remote sensing at a hierarchy of scales

2. To examine the feasibility of estimating vertical profiles of soil moisture and temperature by combining in situ data, remote sensing measurements at the surface, and modeling techniques

3. To evaluate the influence of soil moisture on the local surface energy budget and the influence of mesoscale variability in the surface energy budget on the development of convective boundary layer

The SGP97 Hydrology Experiment as it has developed is a collaboration by a team of interested scientists largely based on existing sponsored scientific investigations and research projects. Cooperation and contributions by many have resulted in a comprehensive opportunity for multidisciplinary research. Version 1 of the SGP97 data, available for general research use, is expected in September 1998.
