TM4-ECPL calculates a total Iron (TFe) atmospheric deposition flux to the Earth’s surface of about 37 Tg-Fe yr-1, for the PRESENT atmosphere. The spatial distribution of TFe deposition flux reflects primarily the Fe-containing minerals sources over dust regions, but also the emissions from fossil fuel combustion processes, oil combustion from ships over ocean and biomass burning. Thus, the highest annual deposition fluxes of TFe are calculated over the Sahara and Gobi deserts and the secondary maxima over mid-latitudes of the Northern Hemisphere where anthropogenic and natural combustion processes occur.
