Dr. Ryan M. Stauffer is a Research AST in the NASA/GSFC Atmospheric Chemistry and Dynamics Laboratory (Code 614). He analyzes long-term records of balloon-borne ozonesonde profile data, and the links among the ozone profiles, meteorology, and near-surface pollution. He serves as the Principal Investigator for the Southern Hemisphere Additional Ozonesondes (SHADOZ) tropical ozonesonde network. Dr. Stauffer has also participated in numerous field projects focused on near-surface and tropospheric air quality and pollution including CAPABLE, DISCOVER-AQ, SEAC4RS, KORUS-AQ, OWLETS, and SCOAPE. He is currently a member of the Assessment of Standard Operating Procedures for Ozonesondes (ASOPOS) expert panel, and is leading an ASOPOS Task Team to examine data quality issues in the global ozonesonde network. He also serves as the Co-Chair of the Sonde Working Group on the Network for the Detection of Atmospheric Composition Change (NDACC) Steering Committee.

Current Projects
SHADOZ Ozonesonde Network
Ozone
The SHADOZ network is an international effort currently led by PI Dr. Ryan M. Stauffer (Founding PI Dr. Anne M. Thompson) to facilitate regular ozonesonde profiling at tropical and subtropical locations. Website: https://tropo.gsfc.nasa.gov/shadoz/
Satellite Coastal and Oceanic Atmospheric Pollution Experiment (SCOAPE)
Pollution
The SCOAPE Project aims to test the feasibility of measuring air quality and emissions from oil and natural gas operations in coastal waters surrounding the US, with a focus on the Gulf of Mexico. The project is an interagency partnership between the Bureau of Ocean Energy Management (BOEM) and NASA, and is lead by PI Bryan Duncan, Chief Scientist Anne Thompson, and Project Manager Debra Kollonige. The project is divided into two major segments 1) A comprehensive report on past and current observations of air quality from satellites and ship-based sampling campaings in coastal waters including DANCE (Mid-Atlantic US in Summer 2014) and KORUS-OC (South Korea in Spring 2016) and 2) A 9-day cruise campaign in the Gulf of Mexico in May 2019.
