The tropospheric concentration of PM is dominated by windblown dust and biomass smoke. Regional haze from fossil fuel combustion is also evident over Eastern China, Northern India, North America and Europe. The tropospheric ozone exhibits excess values during the warm season in the northern hemisphere but there is also an excess ozone bulge emanating from South Africa in the Austral Spring. The spatial and temporal pattern of tropospheric PM and ozone will be summarized using climatological and event-based views as well as the methods of investigation (satellite remote sensing, international field studies and web-based collaboration).
