Abstract: Monitoring the Water Cycle from Space
Monitoring the water cycle is crucial for ensuring food and water security now and in the future.Ìý In the U.S. and certain other first world nations many types of observations that are useful for water cycle monitoring are collected and made available, however, in less developed countries these observations are often sparse, not centralized, and/or not made available to the public.Ìý Even in the U.S. there are vast areas that are not well sampled by ground based measurements.Ìý This is the motivation for airborne and satellite based remote sensing of the water cycle, much of which has been pioneered by NASA.Ìý Hydrometeorological variables that can be inferred from space include precipitation, soil moisture, surface water location and elevation, snow cover and depth, and terrestrial water storage (the sum of groundwater, soil moisture, surface waters, and snow).Ìý In this presentation I will provide an overview of various satellite missions and how their data are used for hydrological science and applications.Ìý I then discuss the NASA/German Gravity Recovery and Climate Experiment (GRACE) satellite mission and the GRACE Follow On mission, discoveries that have been made using GRACE, how the data can be integrated with other observations within a land surface model, and practical applications.
