Between 2007 and 2019, across much of the United States, nitrogen dioxide pollution levels dropped because of cleaner cars and power plants, the team found, confirming findings reported previously. The clean air trend in satellite data was most obvious in urban areas of California, Washington and Oregon and in the eastern half of the continental United States… However, several areas stuck out with increased emissions of nitrogen dioxide: The Permian, Bakken and Eagle Ford oil and gas basins, in Texas and New Mexico, North Dakota, and Texas, respectively.

The new study provides additional insight into a question that has puzzled scientists for the past decade: what has been causing the increase in global methane levels since 2007?
