    • Ambient aromatic hydrocarbon measurements at Welgegund, South Africa 

      Jaars, K.; Beukes, J.P.; Van Zyl, P.G.; Venter, A.D.; Josipovic, M.; Pienaar, J.J.; Tiitta, P.; Laakso, L. (EGU, 2014)
      Aromatic hydrocarbons are associated with direct adverse human health effects and can have negative impacts on ecosystems due to their toxicity, as well as indirect negative effects through the formation of tropospheric ...
    • Characterization of satellite-based proxies for estimating nucleation mode particles over South Africa 

      Sundström, A.-M.; Laakso, L.; Beukes, J.P.; Van Zyl, P.G.; Josipovic, M.; Venter, A.D.; Jaars, K.; Pienaar, J.J.; Piketh, S.; Chiloane, E.K. (EGU, 2015)
      Proxies for estimating nucleation mode number concentrations and further simplification for their use with satellite data have been presented in Kulmala et al. (2011). In this paper we discuss the underlying assumptions ...
    • Chemical composition, main sources and temporal variability of PM1 aerosols in southern African grassland 

      Tiitta, P.; Beukes, J.P.; Van Zyl, P.G.; Josipovic, M.; Venter, A.D.; Jaars, K.; Pienaar, J.J.; Laakso, L. (EGU, 2014)
      Southern Africa is a significant source region of atmospheric pollution, yet long-term data on pollutant concentrations and properties from this region are rather limited. A recently established atmospheric measurement ...
    • Plume characterization of a typical South African braai 

      Venter, A.D.; Jaars, K.; Booyens, W.; Beukes, J.P.; Van Zyl, P.G.; Josipovic, M.; Hendriks, J.; Laakso, L. (SACI, 2015)
      To braai is part of the South African heritage that transcends ethnic barriers and socio-economic groups. In this paper, a comprehensive analysis of atmospheric gaseous and aerosol species within a plume originating from ...
