Houser, P., 2013-2016: Hyper-resolution Terrestrial Forcing (HTF): Development, evaluation and global production. Step-1 Proposal submitted to NASA-ROSES-2012 A4: Terrestrial Ecology (NNH12ZDA001N-TE), 0.1 FTE/yr (CREW). Agency POC:Dr. Diane Wickland (202/358-0245, diane.e.wickland@nasa.gov)

Summary: I propose to develop a global, hourly, 500-m Hyper-resolution Terrestrial Forcing (HTF) land surface weather boundary condition dataset (near-surface air temperature and humidity, wind speed and direction, incident longwave and shortwave radiation, and precipitation), spanning ~5 years (2010-2014). The HTF dataset will be based on a globally downscaled numerical weather forecast analysis first guess, integrated with satellite observed precipitation, radiation and temperature. Temporal and spatial downscaling will be performed using a combination of topographic interpolation (temperature/humidity lapse rate corrections, radiation slope corrections) and an artificial neural network trained with satellite-derived air temperature, land use, topography and high-resolution weather observation networks. Additional sanity, quality control, buddy and consistency checks will be made for the seven downscaled and integrated HTF variables. Evaluation will be performed using data withholding experiments and observations from research networks to determine HTF dataset uncertainty estimates.

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).
