Short summary
Iron (Fe) species in size-fractionated aerosol particles collected in the western Pacific Ocean were determined to identify factors controlling fractional Fe solubility. We found that labile Fe was mainly present in submicron aerosol particles, and the Fe species were ferric organic complexes combined with humic-like substances (Fe(III)-HULIS). The Fe(III)-HULIS was formed by atmospheric processes. Thus, atmospheric processes play a significant role in controlling Fe solubility.
