Figure 7From: Modeling in Earth system science up to and beyond IPCC AR5 Atmospheric loading of total aerosol iron (ng m−3 ) versus percent of soluble iron in total iron. (a) Model results (red circles) of Ito ([2013]) and (b) observations (black crosses) over the oceans from 2001 to 2006. Aerosol iron solubility is plotted against iron loading on a log10 scale to emphasize values at low solubility in Figure eight (a) and (b) of Ito ([2013]).Back to article page
