About
Peter R. Colarco is a leading atmospheric scientist at NASA whose research has fundamentally advanced our understanding of global aerosol distributions, reanalysis systems, and their interactions with climate and weather. Best known for his pivotal contributions to NASA's MERRA-2 aerosol reanalysis—a landmark study accumulating nearly 930 citations—Colarco has helped establish the foundational datasets researchers worldwide rely on to study atmospheric particles spanning four decades of satellite observations. His 2010 work integrating the GOCART aerosol module into the NASA GEOS-4 model (752 citations) transformed how scientists simulate and predict aerosol behavior globally, enabling more accurate online coupled modeling approaches. Colarco has also made significant strides in biomass burning emission datasets, multi-model ensemble evaluation through the International Cooperative for Aerosol Prediction (ICAP), and aerosol impacts over challenging regions including South Asia and the Arctic. His research extends to novel retrieval techniques, including pioneering nighttime smoke aerosol optical depth measurements using VIIRS moonlight observations. By bridging satellite remote sensing, ground-based observations, and sophisticated Earth system modeling, Colarco's body of work—with thousands of cumulative citations—continues to shape operational aerosol forecasting, climate research, and our understanding of how airborne particles influence global atmospheric dynamics.
