The Hydrological Sciences Laboratory examines the role of water in the Earth system. Laboratory researchers strive to better understand, quantify, and analyze the hydrological cycle and to measure hydrological processes in order to improve prediction of the response of global hydrology to anthropogenic and/or natural climate change.

Special emphasis is placed on land surface hydrological processes and their interactions with the atmosphere. Laboratory scientists develop remote-sensing and modeling techniques to investigate how the various components of the hydrological cycle interact over a broad range of spatial and temporal scales.
