Project: Aerosol Behaviour on the South African Highveld

Staff: Helfried Scheifinger

Co-operation: G. Held (ESKOM, South Africa)

Summary: Five atmospheric aerosol species (F-, PO43-, Cl-, NO3- and SO42-) have been monitored over a period of five years at up to 15 stations simultaneously on the South African Highveld, where a major industrial area on the Southern African subcontinent is situated. Their variation of concentration in various time and spatial scales could be related to weather and air mass transport patterns of the subcontinent.
