Title: Research Scientist
Technical Focus Area: Climate Science
Study Topics: geostationary derived broadband fluxes, diurnal flux modelling, imager inter-calibration
David Doelling is a Physical Scientist at NASA Langley Research Center since 2008 and has over 30 years of experience in remote sensing. He is the lead for the Clouds and the Earth’s Radiant Energy System (CERES) responsible for the diurnal averaging and spatial gridding of CERES footprint cloud and radiative flux parameters. He incorporates hourly geostationary (GEO) derived broadband fluxes in order to infer the diurnal cycle in between CERES Terra and Aqua measurements. He is also a member of the Geostationary Earth Radiation Budget (GERB), Megha-Tropiques, Deep Space Climate Observatory (DSCOVR) science teams, projects similar to CERES that measure broadband fluxes. Prior to working on CERES he was a member of the Earth Radiation Budget Experiment (ERBE) team. He has studied the orbital sampling errors for proposed satellites as a member of the Climate Absolute Radiance and Refractivity Observatory (CLARREO) science definition team. In addition, he has performed limited scan angle sampling studies for the Radiation Budget Instrument (RBI) project. He is an expert in simultaneous nadir overpass (SNO) inter-calibration, as well as deep convective clouds (DCC), desert and polar ice invariant target calibration. He has pioneered the use of DCC as an invariant calibration target and spectral band adjustment factors (SBAF) derived from SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY). He is the Global Spaced-based Inter-calibration System (GSICS) visible calibration lead, which is an international effort designed to uniformly calibrate operational satellite sensors across the many agencies. He is leading the GSICS effort to apply his DCC calibration technique across all current operational GEOs. He has calibrated 38 GEO visible imagers, all 16 AVHRR sensors and many LEO imagers. For CERES, he monitors closely the calibration stability of MODIS, and VIIRS and closely with Jack Xiong’s NASA calibration team.
