Michael G. Bosilovich

Dr. Michael G. Bosilovich is a Senior Meteorologist at NASA’s Goddard Space Flight Center whose work focuses on understanding the Earth system through the lens of atmospheric reanalyses. His research centers on Earth’s water and energy cycles and the ways reanalyses can be used to study global and regional hydrology, low-frequency climate variability, extreme weather, planetary boundary layer processes, and land–atmosphere interactions, while also characterizing uncertainty across different reanalysis products.

Dr. Bosilovich is especially known for advancing the applied use of NASA reanalysis products (including MERRA-2) to bridge research and societal needs, supporting sectors that rely on robust meteorological information and helping develop diagnostics and tools that make these data applicable to real-world decision-making. His current work includes evaluating how reanalyses represent the U.S. regional water cycle, expanding applications to data-sparse regions such as the Arctic, and developing enhanced observation/innovation datasets to support MERRA-2 and future GEOS products.

Dr. Bosilovich has served as a NASA scientist since 2000, following a USRA postdoctoral appointment focused on land–atmosphere studies and water-vapor source/sink simulations. He contributes broad professional service, including long-running editorial leadership as an Associate Editor for the Journal of Hydrometeorology, as well as roles within GEWEX and other community efforts.

His honors include the Presidential Early Career Award for Scientists and Engineers (PECASE) and NASA Honors Group Achievement Awards recognizing the MERRA and MERRA-2 teams.

He holds a B.S. in Meteorology (Millersville University) and an M.S. and Ph.D. in Atmospheric Science (Purdue University).
