Interpretive Summary: Accurate evaluation of runoff and soil climate in very large agricultural watersheds requires tracking water and thermal energy balances over large ungaged areas. Several partnerships with scientists from other federal agencies and universitities were formed to support this research effort. Through these partnerships, research is conducted in the intensively instrumented ARS Goodwin Creek Experimental Watershed in northern Mississippi to develop and test new technology for monitoring distributions of rainfall, surface solar radiation, and soil moisture and soil temperature over watersheds and river basins. Long term in situ and remote observations, nearly impossible 10 tears ago, are now carried out routinely using new cost-effective technologies. Access to this new accurate, distributed data will enhance the ability of producers and hydrologists to make optimum decisions in agricultural production, water resources management, and flood and drought protection.
Technical Abstract: Scientists at the USDA-ARS National Sedimentation Laboratory (NSL) are engaged in a number of remote sensing activities related to research studies on hydrometeorology. These studies are conducted on the ARS-NSL Goodwin Creek Experimental Watershed in cooperation with researchers from other Federal Agencies and from Universities. This paper presents brief summaries of these research efforts and their outcomes.
