Program Manager: Bradley Doorn, NASA-Headquarters
Dr. Bradley Doorn transferred to the Earth Science Division in April 2009. He is the Program Manager for Agriculture, Carbon, and Water applications in the Applied Science Program.
Previously, Dr. Doorn was the Division Director of the International Production Assessment Division in the Office of Global Analysis, Foreign Agricultural Service (FAS), U.S. Department of Agriculture (USDA). As Director he also managed the USDA Remote Sensing Program applied to global agriculture monitoring and the USDA Satellite Imagery Archive (SIA). The FAS is the focal point within the U.S. Government for assessing the global crop production and crop conditions that affect world food security and trade. The USDA SIA exploits USDA's extensive use of satellite information by providing centralized contracting and distribution for multiple USDA agencies to reduce cost and expand use.
At USDA for 12 years, Dr. Doorn worked extensively with universities, NASA, USGS, NOAA, USAID, DOD, and other government agencies to improve operational access to existing satellite information. One example of such collaborations was the Global Agriculture Monitoring (GLAM) partnership program that facilitates the utilization of NASA capabilities and transition of satellite data into an operational information flow for decision-makers. Access to satellite imagery and other related information was standardized through web and GIS interfaces for better internal and public use.
Dr. Doorn served on active duty as a U.S. Army Corps of Engineers Topographic Officer, including Company Commander of the 175th Topographic Company in direct support of the XVIII Airborne Corps and Fort Bragg NC facilities. He also spent five years in private industry as a manager and s pecialist in remote sensing, GIS, and mapping for numerous engineering and environmental projects.
A long time member and officer of the American Society for Photogrammetry and Remote Sensing (ASPRS), Dr. Doorn now serves as the President. Other professional duties have included serving as a representative on the NOAA Advisory Committee on Commercial Remote Sensing (ACCRES), USDA's Remote Sensing Coordinating Committee, an appointed member of the National Satellite Land Remote Sensing Archive Advisory Committee (Department of Interior), and a member of the Future of Land Imaging Interagency Working Group (Office of the White House).
A native of South Dakota, Brad earned a BS in Geological Engineering from the South Dakota School of Mines and Technology and a MS and PhD in Geodetic Science and Surveying from The Ohio State University. He resides in York, Pennsylvania with his wife and three children.
Deputy Program Manager:
Jared Entin, NASA-Headquarters
Jared Entin graduated from the University of Maryland with a Ph.D. in Meteorology. He studied the spatial and temporal scales of soil moisture, as well as worked on validation efforts for numerous land surface models through the GEWEX Global Soil Wetness Project. In 1999, Entin started working at the NASA-GSFC Hydrological Processes Branch, where he joined Dr. Paul Houser on the LDAS project in an effort to use TRMM radiometer data to determine soil moisture, and subsequently infuse that information into a land surface model using data assimilation techniques. In 2002, Entin moved to NASA-HQ to manage the Terrestrial Hydrology program, as well as to help guide NASA's efforts in the Global Water and Energy Cycle field. As of mid-2002, the Earth Sciences Enterprise Applications division at NASA-HQ has initiated twelve national applications. Dr. Entin is helping to direct one of these, the Water Management and Conservation application.

Deputy Program Manager:
David Toll, NASA-GSFC
David Toll is active in the research and application of hydrology, microclimatology, and environmental science using remote sensing systems. David Toll has a B.S. in Natural Resources (Wildlife Biology) from Colorado State University (1976), a M.S. in Earth Resources (Remote Sensing) from Colorado State University (1978), and a M.S. in Geography (Microclimatology) from the University of Maryland (1991). He worked in the NASA/GSFC Biospherics Branch from 1978-1988, conducting research on remote sensing of biophysical parameters using primarily optical and thermal infrared systems. He has worked in the GSFC Hydrological Sciences Branch since 1988. Specific areas of interest include the application and improvement of the modeling and remote sensing of land surface water and energy fluxes, and the application of remote sensing technology for water resources applications. He currently is the NASA Deputy Program Manager in Water Management and helps lead projects with the EPA and the Bureau of Reclamation.
