Profile

     Miguel Román is a research physical scientist in the Terrestrial Information Systems Branch at NASA Goddard Space Flight Center. He is part of a multi-agency team of scientists in charge of performing assessments and validation testing for the NPOESS Preparatory Project (NPP) Visible/Infrared Imager Radiometer Suite (VIIRS) Land Environmental Data Records (EDRs). He currently coordinates NASA's validation and scientific investigations in support of NPP-VIIRS Land EDRs. His research is centrally concerned with the development and application of remote sensing, radiative transfer, image processing, and geostatistical techniques to measure and monitor terrestrial essential climate variables. He has participated in several field observation programs (e.g. FLUXNET, NACP, ARM-DoE, and BSRN) and intense observing periods (e.g. ChEAS’06, CLASIC’07, and ARCTAS’08) to coordinate the production of in-depth accuracy and variability assessments for current and future reprocessing of global surface albedo and reflectance anisotropy products. His research at NASA focuses on understanding the relation between vegetation parameters estimated from remotely sensed data at different spatial scales (from both airborne and satellite sensors) and the Bidirectional Reflectance Distribution Function (BRDF) of different surface types and ecosystems.
