A strategy to study regional hydrology and terrestrial ecosystem processes using satellite remote sensing, ground-based data and computer modeling

This paper describes a multidisciplinary research project which seeks to characterize the terrestrial water cycle and use this characterization to derive simulations of carbon dioxide and methane flux. The water cycle work links interpolated climate fields, macrohydrologic models and Scanning Multichannel Microwave Radiometer datasets. The aim of the analysis is to use output from calibrated water balance models to develop relationships with SMMR datasets. SMMR estimates of surface hydrology can then be evaluated. Both modeled and SMMR datasets will be tested as inputs to regional biogeochemical models. All determinations will be made under climatically-averaged conditions and for 1979–1985, the years for which SMMR data is available.
