Measurements of nitrogen dioxide (NO2) concentrations by the GOME-2 instrument on board the MetOp-A satellite from 2011. High values are found in the Highveld region – the economic centre of South Africa, where large cities and heavy industry are concentrated. Due to prevailing westerly and north-westerly winds, the air pollution is transported over a large area.
