Assessment of atmospheric trace metals in the western Bushveld Igneous Complex, South Africa
(ASSAf, 2014)
Trace metal species emitted into the atmosphere from natural and anthropogenic sources can cause various
health-related and environmental problems. Limited data exist for atmospheric trace metal concentrations in
South ...
Modelling new particle formation events in the South African savannah
(ASSAf, 2014)
Africa is one of the less studied continents with respect to atmospheric aerosols. Savannahs are complex
dynamic systems sensitive to climate and land-use changes, but the interaction of these systems with the
atmosphere ...
An air quality assessment in the industrialised western Bushveld Igneous Complex, South Africa
(ASSAf, 2012)
South Africa has the largest industrialised economy in Africa, with significant mining and
metallurgical activities. A large fraction of the South African mineral assets is concentrated in
the Bushveld Igneous Complex ...
A comparison of surface NO2 mixing ratios and total column observations at a South African site
(SASAS, 2014)
The total column density nitrogen dioxide (NO2) retrievals collated by a ground-based
sun-tracking spectrometer (Pandora/GSFC) and the satellite-borne (Aura) Ozone
Monitoring Instrument (OMI) were compared to the volume ...
Measurements of biogenic volatile organic compounds at a grazed savannah grassland agricultural landscape in South Africa
(EGU, 2016)
Biogenic volatile organic compounds (BVOCs) play an important role in the chemistry of the troposphere, especially in the formation of tropospheric ozone (O3) and secondary organic aerosols (SOA). Ecosystems produce and ...
Atmospheric trace metals measured at a regional background site (Welgegund) in South Africa
(EGU, 2017)
Atmospheric trace metals can cause a variety of health-related and environmental problems. Only a few studies on atmospheric trace metal concentrations have been conducted in South Africa. Therefore the aim of this study ...
Free tropospheric aerosols over South Africa
(EDP Sciences, 2016)
Raman lidar data of one year was been analyzed to obtain information relating aerosol layers in the free troposphere over South Africa, Elandsfontein. In total, 375 layers were observed above the boundary layer during the ...
The effect of rainfall amount and timing on annual transpiration in grazed savanna grassland
(EGU, 2020)
The role of precipitation (P) variability on evapotranspiration (ET) and its two components transpiration (T) and evaporation (E) rates from savannas continues to draw significant research interest given its relevance to ...
Summary of research paper published in Journal of Atmospheric Chemistry titled: Assessment of polar organic aerosols at a regional background site in southern Africa
(National Association for Clean Air, 2019)
A recent paper reported GCxGC-TOFMS analysis used for the first
time in southern Africa to tentatively characterise and semiquantify ~1 000 organic compounds in aerosols at Welgegund – a
regional background atmospheric ...
Assessment of polar organic aerosols at a regional background site in southern Africa
(Springer, 2019)
A recent paper reported GCxGC-TOFMS analysis used for the first time in southern Africa to tentatively characterise and semi-quantify ~1000 organic compounds in aerosols at Welgegund – a regional background atmospheric ...
