Brief Bio

Andrea Portier works at NASA Goddard Space Flight Center (GSFC) and serves as Applications Lead for the Global Precipitation Measurement (GPM) Mission and the Applications Coordinator for the Atmosphere Observing System (AOS). In these roles, she engages with different stakeholder communities to understand and quantify how NASA satellite data products are applied for decision-making as well as promote and educate potential users about how NASA data can benefit their work and lives. These efforts include identifying stakeholder interests and requirements for satellite observations, creating strategies to engage and expand the user community, increasing awareness of NASA precipitation and aerosol data products, and improving data access and visualization of satellite products for rapid ingestion and analysis. Prior to working at NASA, Andrea served as a Science Assistant at the National Science Foundation in the Division of Ocean Sciences’ Marine Geology and Geophysics Program. Andrea holds a M.S. in Geological Sciences from University of Florida, and received a B.S. and a B.A. from Ohio State University in Geological Sciences and International Studies.
