Oil and gas operations in the U.S. Outer Continental Shelf of the Gulf release emissions of nitrogen dioxide (NO₂), a gas that contributes to poor air quality. Because it is difficult to measure pollutants over water, NASA and the Bureau of Ocean Energy Management (BOEM) have been collaborating to assess feasibility of using satellite measurements in the region since 2017. This was reflected in two ship campaigns, one in 2019 (SCOAPE-I) and another in 2024 (SCOAPE-II), which focused on comparisons of satellite datasets with coastal and shipboard Pandora instruments. During SCOAPE-II, a major addition was the new geostationary TEMPO instrument which has the ability make hourly observations. While TEMPO NO₂ data could generally detect hotspots and followed similar pollution trends as ground-based instruments like Pandora, the correlation was poor (r < 0.5). Satellites tended to overestimate NO₂ levels onshore and underestimate offshore. Research flights also revealed that drillships may emit as much or more NO₂ than nearby oil platforms. Continued improvements to the satellite data are expected to help better monitor and manage air pollution from offshore sources. This work supports BOEM’s efforts to ensure energy development in the Gulf is both environmentally and economically responsible.
