Aerosol optical properties at a savannah grassland site in South Africa
(North-West University (South Africa), 2020)Atmospheric aerosols affect the earth’s radiative budget in two ways: firstly, particles directly absorb and scatter short- and long-wave radiation and, secondly, particles indirectly influence the lifetime and physical ... -
Characterising particulate organic nitrogen at a savannah-grassland region in South Africa
(MDPI, 2019)Although atmospheric organic N compounds are considered to be important, especially in new particle formation and their contribution to brown carbon, these species are not that well understood. This can be partially ... -
Measurement of organic compounds in atmospheric aerosols collected at Welgegund, South Africa
(North-West University, 2018)Atmospheric aerosols or particulate matter (PM) are a complex mixture of solid and liquid particulates suspended in the atmosphere that originate from natural and anthropogenic sources. These species influence climate ... -
Reevaluating the contribution of sulfuric acid and the origin of organic compounds in atmospheric nanoparticle growth
(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 ... -
Size-resolved characterisation of organic compounds in atmospheric aerosols collected at Welgegund, South Africa
(Springer, 2015)The organic fraction of atmospheric aerosols is 20 to 90 % of which only a small percentage has been chemically characterised. Two-dimensional gas chromatography with a time-of-flight mass spectrometer (GCxGC-TOFMS) is a ...
