Rapid changes in biomass burning aerosols by atmospheric oxidation
(Wiley, 2014)
Primary and secondary aerosol particles originating from biomass burning contribute significantly
to the atmospheric aerosol budget and thereby to both direct and indirect radiative forcing. Based on detailed
measurements ...
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 ...
Six-year observations of aerosol optical properties at a southern African grassland savannah site
(Elsevier, 2020)
Atmospheric aerosols have a significant effect on earth's radiative budget, particularly on regional scales. This paper presents a ~6 year, in situ, ground level aerosol scattering and absorption dataset, measured at a ...
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 ...
The composition of ambient and fresh biomass burning aerosols at a savannah site, South Africa
(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 ...
Root-zone soil moisture variability across African savannas: from pulsed rainfall to land-cover switches
(Wiley, 2020)
The main source of soil moisture variability in savanna ecosystems is pulsed rainfall. Rainfall pulsing impacts water‐stress durations, soil moisture switching between wet‐to‐dry and dry‐to‐wet states, and soil moisture ...
