Nitrogen Dioxide (NO₂)
NO₂ is the lesser of the two emitted NOx gases from high temperature combustion in air. It is an important species in the atmosphere. Since it absorbs in the visible wavelength region (creating the Brown Cloud see over Denver, LA, Mexico City) and can be photolyzed and yield oxygen atoms that can react with molecular oxygen to create ozone, NO₂ and the NO/NO₂ ratio is important.
