Interpretive Summary:

Technical Abstract: Satellite-based remotely sensed data acquired during the Washita '94 hydrologic field experiments were used in combination with a dense comprehensive environment monitoring network to estimate surface energy fluxes over the Little Washita Watershed (LWW). The USDA Agricultural Research Service Grazinglands Research Laboratory maintains the LWW near Chickasha, Oklahoma. The watershed is composed of a mixture of cropland and rangeland in a sub-humid environment. In addition, six surface flux sites, which consisted of Bowen ratio or eddy correlation instruments, were installed at select locations throughout the watershed. The research described here used a Landsat Thematic Mapper (TM) scene together with ground data to create a 120m resolution image of spatially distributed parameters for mapping the sensible, latent, and ground heat fluxes over the watershed. The surface flux station data was the used to validate the spatially distributed maps.
