(a) Map of the Southern Hemisphere dust sources included in this study (b) PM10 concentration (mg m−3) from the dust generation experiments with ±1 standard deviation. PM10 values from Little Desert Transect are aggregated. (c) The dust potential per unit mass (mg m−3 g−1, with ±1 standard deviation) for the Makgadikgadi Pan (MG), Etosha Pan (ET), southern Kalahari interdunes (ID) and the Mallee dune crests (DC), interdune (ID), salt pan (SP) and little desert (LD) (d) Iron-in-dust potential (μg m−3, with ±1 standard deviation) is calculated by multiplying PM10 concentration with the ferrous ion, Fe(II) (grey bars) and with total soluble iron (FeTS) (white bars). (Information on the PM10 concentration from Southern African dust sources are available in Supplementary Table S1). This map was created in ArcGIS (ESRI, Redlands, CA).
