Our focus within Hydrological Sciences is to develop remote sensing and modeling techniques which will improve our understanding of how the various components of the hydrological cycle interact over a broad range of spatial and temporal scales, thus producing important information about the current structure of global hydrology and how man kind is changing the hydrological environment.
Mean annual fluxes (1000 km3/yr) of the global water cycle, and associated uncertainties, during the first decade of the millennium. White numbers are based on observational products and data integrating models. Blue numbers are estimates that have been optimized by forcing water and energy budget closure, taking into account uncertainty in the original estimates. From Rodell, M., Beaudoing, H. K., L’Ecuyer, T. S., Olson, W. S., Famiglietti, J. S., et al. (2015).

SMAP uses a 1.4 GHz microwave radiometer, a high-resolution 1.2 GHz radar, and a combination of the two instruments to measure surface soil moisture and freeze-thaw state, providing new opportunities for scientific advances and societal benefits.
Aqua, Latin for water, is a NASA Earth Science satellite mission named for the large amount of information that the mission is collecting about the Earth's water cycle, including evaporation from the oceans, water vapor in the atmosphere, clouds, precipitation, soil moisture, sea ice, land ice, and snow cover on the land and ice.
