TL;DR: In this paper, a comprehensive air quality monitoring station was operated for more than 2 years in the western part of the Bushveld Igneous Complex (BIC), where meteorological parameters, trace gas concentrations and total mass concentration of particulate matter up to 10 µm in size (PM 10 ) were measured.

TL;DR: In this article, the authors reported that new particle formation and growth rates were among the highest reported in the literature for continental boundary layer locations; median 10 nm formation rate was 2.2 cm−3 s−1 and median 10-30 nm growth rate 8.9 nm h−1.

TL;DR: In this article, the authors analyzed one year (July 2006-July 2007) of measurement data from a relatively clean background site located in dry savannah in South Africa, and the annual median total particle number concentration in the size range 10-840 nm was 2340 cm −3.

TL;DR: In this paper, the authors used permanently installed CO 2 probes to determine the CO 2 profile in a boreal coniferous forest soil and calculated CO 2 efflux from the concentration profile with a dynamic model.

TL;DR: In this article, the authors introduce new in situ observations of atmospheric aerosols, especially chemical composition, physical and optical properties, on the eastern brink of the heavily polluted Highveld area in South Africa.
