Brief Bio


Dr. Peter Colarco is a research physical scientist in the Atmospheric Chemistry and Dynamics Laboratory at the NASA Goddard Space Flight Center. He leads research on the distributions and properties of atmospheric aerosols, and their impacts on Earth’s weather and climate system. His main research tools are global atmospheric circulation models and remote sensing observations. Dr. Colarco implemented and coupled the aerosol module currently used for near-real time forecasting and climate simulation in the NASA GEOS-5 Earth system model. He participates in numerous studies to validate Earth system model representations of aerosols, including developing detailed simulators of remote sensing observations, most recently for the CALIOP and OMI space-based sensors. He is also developing new representations for stratospheric aerosols in GEOS-5. Dr. Colarco has been a PI of a number of NASA funded research efforts and has authored or co-authored more than 50 peer-reviewed papers. He has supported a number of NASA airborne field campaigns as a forecaster and flight planner. Dr. Colarco is additionally a co-chair of the International Cooperative for Aerosol Prediction (ICAP), a grassroots effort to coordinate the activities of global aerosol forecasting centers, model developers, and data providers.
