Remote Sensing of Land Water Mobility
Satellite remote sensing land atmosphere water and energy exchange.
The lack of available water constrains hydrologic and ecological processes for two-thirds of the Earth’s land surface. We are working with colleagues at the NASA Jet Propulsion Laboratory to develop new satellite microwave remote sensing algorithms for detecting and monitoring land-atmosphere water and energy exchange over North America. These data will provide continuous weekly-annual observations of surface evaporation and vegetation conditions from 1988 onward that can be used for a variety of applications including monitoring agricultural, rangeland and forest health, improving regional weather forecasts and water resource monitoring. Regional and global data sets developed from this project include satellite based evapotranspiration (ET), terrestrial freeze-thaw status and net primary productivity (NPP).
