NO2

Exposure to air pollution has been shown to lead to adverse health effects. A major air pollutant is NO2, which, at the surface level, directly affects human health, and, at higher elevations, contributes to acidic rain and represents a precursor to greenhouse gases. While NO2 column densities in the atmosphere can be measured with satellite observations as provided by Sentinel-5P, it requires in-situ measurements from ground stations to measure NO2 concentrations on the surface level, which is relevant to human exposure. ...
