The transport of atmospheric NO<sub>x</sub> and HNO<sub>3</sub> over Cape Town

The transport of atmospheric NO<sub>x</sub> and HNO<sub>3</sub> over Cape Town

Cape Town, the most popular tourist city in Africa, usually experiences air pollution with unpleasant odour in winter. Previous studies have associated the pollution with local emission of pollutants within the city. The present study examines the transport of atmospheric pollutants (NO<sub>x&...
