The scientists used a method to measure nitrogen dioxide in the air from an airplane during a study in Texas. They found that this method can help track the amount of nitrogen dioxide in the air and where it comes from, like power plants. By studying nitrogen dioxide plumes, they estimated how much nitrogen oxide is released by power plants in Houston, Dallas, and North Carolina. They also figured out the total amount of nitrogen dioxide coming from Houston.
