Africa burning: a thematic analysis of the Southern African regional science initiative (SAFARI 2000)

Author: Swap, RJ ; Annegarn, HJ ; Suttles, JT ; King, MD ; Platnick, S ; Privette, JL ; Scholes, RJ Date: Jul 2003 The Southern African Regional Science Initiative (SAFARI 2000) was a major surface, airborne, and space borne field campaign carried out in southern Africa in 2000 and 2001 that addressed a broad range of phenomena related to land-atmosphere ...

Biogenic, biomass and biofuel sources of trace gases in southern Africa

Author: Otter, LB ; Marufu, L ; Scholes, MC Date: Mar 2001 Biogenic processes in southern African savannas are estimated to produce 1.0 Tg NO yr(-1), 44.2-87.8 Tg C yr(-1) as non-methane hydrocarbons (NMHCs) and to consume 0.23 Tg CH4 yr(-1). Floodplains and wetlands in southern Africa are estimated ... Read more
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
The consideration of non-anthropogenic emissions for air quality modelling in South Africa

Author: Naidoo, M ; Piketh, S Date: Oct 2015 Air quality modelling requires the identification of all relevant sources of emissions and the accurate calculation of the emissions rates. Many of these sources include anthropogenic activities that need to be accounted for in any emissions ... Read more
Effective single scattering albedo estimation using regional climate model

Author: Tesfaye, M ; Tsidu, M ; Sivakumar, V ; Botai, J Date: Sep 2011 In this study, by modifying the optical parameterization of Regional Climate model (RegCM), the authors have computed and compared the Effective Single-Scattering Albedo (ESSA) which is a representative of VIS spectral region. The arid, ... Read more
Generating emissions and meteorology to model the impacts of biomass burning emissions on regional air quality in South Africa

Author: Carter, WS ; Zunckel, M ; Diab, R Date: Oct 2008 Biomass burning is a source category that is often ignored in pollution dispersion modelling simulations. This study presents a unique contribution to the quantification of emissions from biomass burning for high resolution modelling. Previous ... Read more
Rainwater composition in northeast Uruguay

Author: Zunckel, M ; Saizar, C ; Zarauz, J Date: Apr 2003 The aim in this paper is threefold: firstly to gain an initial understanding of rainwater chemistry in the northeast of Uruguay; secondly to identify possible sources that contribute to its chemical composition; and thirdly to establish a ...

Southern Africa - a giant natural photochemical reactor

Author: Diab, RD ; Naidoo, M ; Zunckel, M ; Carter, WS Date: Apr 2006 The analogy of a ‘giant natural photochemical reactor’ is extended in this paper to the central and southern African tropics, where tropospheric ozone enhancement occurs over a vast geographical area from the Congo to South Africa, and over ...

Trace gas variations at Cape Point, South Africa, during May 1997 following a regional biomass burning episode

Author: Brunke, EG ; Labuschagne, C ; Scheel, HE Date: 2001 During the continuous monitoring of atmospheric parameters at the station Cape Point (34 degrees S, 18 degrees E), a smoke plume originating from a controlled fire of 30 year old fynbos was observed on 6 May 1997. For this episode, which was ... Read more
