Photo Biography
Paul Stackhouse, Jr., Ph.D. Paul Stackhouse, Jr., Ph.D.
Senior Research Scientist
Dr. Stackhouse is a Senior Research Scientist at the NASA Langley Research Center in Hampton, Virginia and leads the POWER team. He also leads the NASA/Global Energy and Water Cycle Experiment (GEWEX) Surface Radiation Budget (SRB) Project, and is a science team member of the Clouds and Earth Radiant Energy System (CERES) project and co-leads the FLASHFlux (Fast Longwave and Shortwave radiative Fluxes) working group. Both project produce radiative fluxes using satellite analysis and the latter produces low latency estimates of top-of-atmosphere and surface radiation data products from CERES. Both of the these data sets are key inputs to the POWER Web Suite. As lead for POWER, Dr. Stackhouse works to connect the physical parameters provide by NASA Earth Observations to the user community by working with leaders in the renewable energy, energy efficiency and agroclimatology fields. Thus, he leads the formulation for community requested parameters, reviews validation, assessments and documentation. Dr. Stackhouse completed his M.S. and Ph.D. in Atmospheric Sciences at Colorado State University in 1989 and 1995 respectively.
Taiping Zhang Taiping Zhang, Ph.D
Senior Research Scientist
Dr. Taiping Zhang has a Master of Science from Tianjin University (1987) and a Ph.D. from Yale University (2003). He has been working on the NASA GEWEX SRB and POWER projects since 2003 as a senior research scientist. His work focuses on 1.) The quality control and processing of surface-based shortwave and longwave radiation measurements that include data from the BSRN, SurfRad, GEBA and WRDC archives; 2.) Application of the surface-based data in validation of the satellite-based GEWEX SRB radiation data products and POWER SSE data products; 3.) Climatological analysis of the GEWEX SRB data products; 4.) Production of the direct normal irradiance for the POWER SSE using the DirIndex global-to-beam model with the GEWEX SRB global horizontal irradiance and other auxiliary data as inputs.

David Westberg David Westberg
Staff Researcher
David Westberg was a staff researcher for the NASA POWER project team. He has Bachelor's and Master's Degrees in Atmospheric and Oceanic Sciences from the University of Wisconsin - Madison. His main duties are to validate the meteorological data sets against global surface observing sites, as well as provide ways to improve the quality of the data sets. He also acts as a liaison between the NASA POWER project team and the ASHRAE Technical Committee - 4.2, which is in charge of the 'Climatic Design Information' chapter of the ASHRAE Handbook of Fundamentals produced every 4 years.
Bill Chandler Bill Chandler
Senior Atmospheric Scientist
Bill Chandler was a Senior Atmospheric Scientist and the lead software developer of the Solar meteorology and Solar Energy website (SSE) that was a precursor to the current POWER web site to which he also contributed. He contributed numerous papers and talks discussing the data services provided to the solar energy and agroclimatology communities. Sadly, he passed away in 2017.
Charles Whitlock Charles Whitlock
Senior Atmospheric Scientist
Dr. Charles Whitlock was the original leader of the Surface meteorology and Solar Energy project (SSE) that was the precursor to the current POWER web site. Dr. Whitlock also served to lead the NASA Langley Surface Radiation Budget project which was utilized for the first SSE data products provided to the public. After his retirement from NASA he continued to work and contribute to the theoretical development of many of the value added data products that POWER still features today. Sadly, Dr. Whitlock passed away in 2018.
