The Global Energy and Water Cycle Experiment (GEWEX) Continental-scale International Project (GCIP) Integrated Systems Test (GIST) takes place in the Arkansas-Red River basins as a data system test prior to the start of the 5 year GCIP Enhanced Observing Period (1995-2000). The Arkansas and Red River basins provide a number of watershed areas that are potentionally useful for hydrologic focussed studies. The GIST Data Set constitutes the third in a series of GCIP Initial Data Sets (GIDS-3).

Objectives:

1. Demonstrate to the satisfaction of the scientific community, the adequacy of a GCIP data collection and management system for an initial set of diagnostic, evaluation, and modeling studies
2. Rectify any data system modifications identified in time for providing the services needed during the Enhanced Observing Period.
