Changes in ground-based solar ultraviolet radiation during fire episodes: a case study

Author: Wright, CY ; Archibald, S ; Garland, Rebecca M ; Naidoo, M ; Frost, F ; Phala, N Date: Sep 2013 Solar ultraviolet radiation (UVR) levels are affected by airborne aerosols, such as particles and gases released during biomass burning events. Two large-scale fires in South Africa were identified and selected based on their proximity to ... Read more
Characterizing light-absorbing aerosols in a low-income settlement in South Africa

Author: Xulu, NA ; Piketh, SJ ; Feig, GT ; Lack, DA ; Garland, Rebecca M Date: Aug 2020 Light-absorbing aerosols, particularly black carbon (BC), have significant impacts on human health and the climate. They are also the least-studied fraction of atmospheric particles, particularly in residential areas of southern Africa. The ... Read more
Climate change and health within the South African context: A thematic content analysis study of climate change and health expert interviews
