    • The composition of ambient and fresh biomass burning aerosols at a savannah site, South Africa 

      Aurela, Minna; Beukes, Johan P.; Van Zyl, Pieter; Laakso, Lauri; Vakkari, Ville (ASSAf, 2016)
      Atmospheric aerosols play a key role in climate change, and have adverse effects on human health. Given South Africa’s status as a rapidly-developing country with increasing urbanisation and industrial growth, information ...
    • Major secondary aerosol formation in southern African open biomass burning plumes 

      Vakkari, Ville; Beukes, Johan P.; Josipovic, Miroslav; Van Zyl, Pieter G.; Dal Maso, Miikka (Nature, 2018)
      Open biomass burning contributes significantly to air quality degradation and associated human health impacts over large areas. It is one of the largest sources of reactive trace gases and fine particles to Earth’s atmosphere ...
    • A novel post-processing algorithm for Halo Doppler lidars 

      Vakkari, Ville; Van Zyl, Pieter G.; Manninen, Antti J.; O'Connor, Ewan J.; Schween, Jan H. (EGU, 2019)
      Commercially available Doppler lidars have now been proven to be efficient tools for studying winds and turbulence in the planetary boundary layer. However, in many cases low signal-to-noise ratio is still a limiting ...
    • Reevaluating the contribution of sulfuric acid and the origin of organic compounds in atmospheric nanoparticle growth 

      Vakkari, Ville; Tiitta, Petri; Jaars, Kerneels; Beukes, Johan Paul; Josipovic, Miroslav; Venter, Andrew D.; Van Zyl, Pieter G.; Laakso, Lauri (Wiley, 2015)
      Aerosol particles formed in the atmosphere are important to the Earth's climate system due to their ability to affect cloud properties. At present, little is known about the atmospheric chemistry responsible for the growth ...
    • Regional atmospheric Cr(VI) pollution from the Bushveld Complex, South Africa 

      Venter, Andrew Derick; Beukes, Johan Paul; Van Zyl, Pieter Gideon; Josipovic, Miroslav; Jaars, Kerneels; Vakkari, Ville (Elsevier, 2016)
      Hexavalent chromium, Cr(VI), is a proven human carcinogen. Of interest in this paper was the regional atmospheric pollution of Cr(VI) from the ferrochromium and related industries located in the western Bushveld Complex ...
