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.
