Quantifying Arctic Water and Energy Cycle Change

A CREW proposal submitted to NASA-ROSES-2012 A12: CRYO: Cryospheric Science (NNH12ZDA001N-CRYO), $349,991, 1 mo/yr, 01/01/2013 – 12/31/2015.

I propose to use historical, satellite and newly available observational contributions to quantify arctic water and energy cycle change, its sensitivity to climate change and variability, its impact on global cycles, and its predictability. Changes in the Greenland ice sheet and the volume and extent of arctic sea ice are critical components of the arctic water and energy balance; the proposed project will contextualize the feedbacks of arctic ice dynamics and change within the arctic water and energy cycle. This project will collect, integrate and diagnose disparate, multi-variate historical and emerging arctic observations and model predictions in a consistent framework. The first step will focus on discovery and integration of arctic water and energy cycle observation and predictions. The second step will focus on developing process understanding through analysis of the integrated water and energy cycle information, involving (a) examination of the historical arctic water and energy cycle record to assess long-term change and uncertainty and our ability to predict these changes, (b) re-examination of arctic water and energy cycling using enhanced observation and prediction capacities, and (c) examination of linkages the between the arctic and global water and energy cycles and its implications. This investigation should ultimately improve the understanding of arctic region feedbacks on climate and NASA’s observationally based capability to predict the variations of the arctic water and energy cycle.

About the Author (Author Profile)

Dr. Houser in an internationally recognized expert in local to global land surface-atmospheric remote sensing, in-situ observation and numerical simulation, development and application of hydrologic data assimilation methods, scientific integrity and policy, and global water and energy cycling. He received his B.S. and Ph.D. degrees in Hydrology and Water Resources from the University of Arizona in 1992 and 1996 respectively. Dr. Houser's previous experience includes internships at the U.S. Geological Survey and at Los Alamos National Laboratory. Dr. Houser joined the NASA-GSFC Hydrological Sciences Branch and the Data Assimilation Office (DAO/GMAO) in 1997, served as manager of NASA’s Land Surface Hydrology Program, and served as branch head of the Hydrological Science Branch. In 2005, he joined the George Mason University Climate Dynamics Program and the Geography and Geoinformation Sciences Department as Professor of Global Hydrology, and formed CREW (the Center for Research for Environment and Water). Dr. Houser has also teamed with groundwater development and exploration companies (EarthWater Global and Geovesi) and has served as Science Advisor to the U.S. Bureau of Reclamation. Dr. Houser has led numerous scientific contributions, including the development of Land Data Assimilation Systems (LDAS), the Hydrospheric States Mission (Hydros/SMAP), the Land Information System (LIS), the NASA Energy and Water cycle Study (NEWS), and the Water Cycle Solutions Network (WaterNet).
