The success of the May 2019 Satellite Coastal and Oceanic Atmospheric Pollution Experiment (SCOAPE) project motivated the Gulf of America Region | Bureau of Ocean Energy Management (BOEM) to renew its partnership with NASA/GSFC in 2022. As with SCOAPE, the primary goal of SCOAPE-II was to explore the ability of NASA resources to monitor and quantify the effects of Gulf of America oil and natural gas (ONG) emissions on coastal US air quality. The April 2023 launch of the Tropospheric Emissions: Monitoring of Pollution (TEMPO) instrument, which is currently collecting hourly daytime measurements of key air pollutants such as nitrogen dioxide (NO₂) and ozone over North America, provides another platform for NASA scientists to leverage to meet BOEM’s needs. In addition to NO₂, emphasis was also placed on assessing methane emissions from ONG activities in SCOAPE-II. The project culminated in a second Gulf air quality cruise near ONG operations in June 2024 that in addition to ship in-situ measurements, included airborne measurements of methane from JPL’s AVIRIS-3 instrument. A second aircraft-only campaign was held over the Gulf in October 2024 with GCAS measurements of NO₂ on the NASA/LaRC B200 King Air. The data from the 2019 and 2024 campaigns are now publicly available at the link below.
