“…For vertical motion, the model was set at the default option zero (0), which uses the meteorological model's vertical velocity fields and the top of the model domain was also set at the default value 10,000 magl [55]. The five day period was selected due to previous studies on intercontinental air transport between South America and South Africa and South America and the Southwest Indian Ocean (SWIO) islands, which showed that this period is sufficient for the upper air transport from South America to South Africa and SWIO islands [30,56]. The 5-year seasonal trajectories were grouped into clusters based on their spatial closeness and each cluster was represented as a mean trajectory.…”

This paper demonstrates the role of meteorology and air transport in influencing the South African atmospheric CO2 distribution. CO2 data from December 2004 to December 2009 acquired by the Tropospheric Emission Spectrometer (TES) instrument onboard the Aura satellite were used to establish the CO2 vertical distribution at selected regions in South Africa. The Hybrid Single-Particle Lagrangian Integrated Trajectories (HYSPLIT) atmospheric model backward trajectories were used to determine the long-range air transport impacting on South African CO2 atmospheric distribution and to detect the source areas of air masses impacting on South Africa’s atmosphere. The study found that long-range air transport can result in the accumulation or dilution of atmospheric CO2 at various sites in South Africa, depending on the source region and type of air flow. The long-range air transport from different source regions at the upper air level between the 700 and 500 hPa stable layers and the layer above 500 hPa strengthens the inhomogeneity in the vertical distribution of CO2, which is caused by the decoupling effect of the upper air stable layers. This long-range air transport also involves intercontinental air transport.
