Abstract:We show that the Landsat and Sentinel-2 satellites can detect NO

plumes from large point sources at 10 to 60 m pixel resolution in their blue and ultrablue bands. We use the resulting NO

plume imagery to quantify nitrogen oxides (NO

) emission rates for several power plants in Saudi Arabia and the United States, including a 13-y analysis of 132 Landsat plumes from Riyadh power plant 9 from 2009 through 2021. NO
