  • Brief Bio

    Dr. Ryan M. Stauffer is a NASA Postdoctoral Program (NPP) Fellow working with advisor Dr. Anne M. Thompson (Code 610) to analyze long-term historical records of ozonesonde profile data.  His work examines the links between the ozone profiles, meteorology, and near-surface pollution.  Dr. Stauffer has also participated in numerous NASA-sponsored field projects focused on near-surface and tropospheric air quality and pollution.  Field projects and measurement networks include SHADOZ, CAPABLE, DISCOVER-AQ, SEAC4RS, and KORUS-AQ.  His work during the NPP Fellowship will include validation of MERRA-2 reanalysis data and chemical transport model (CTM) output.

    Current Projects

    SHADOZ Ozonesonde Network

    The SHADOZ network is an international effort lead by PI Dr. Anne M. Thompson to facilitate regular ozonesonde profiling at tropical and subtropical locations.  Website: https://tropo.gsfc.nasa.gov/shadoz/
