Our results suggest that mineral aerosols are the dominant source of TP on a global scale (82\%), with primary biogenic particles (12\%) and combustion sources (5\%) important in nondusty regions. Globally averaged anthropogenic inputs are estimated to be \~{}5 and 15\% for TP and PO<sub>4</sub>, respectively, and may contribute as much as 50\% to the deposition over the oligotrophic ocean where productivity may be phosphorus-limited. There is a net loss of TP from many (but not all) land ecosystems and a net gain of TP by the oceans (560 Gg P a<sup>-1</sup>). More measurements of atmospheric TP and PO<sub>4</sub> will assist in reducing uncertainties in our understanding of the role that atmospheric phosphorus may play in global biogeochemistry.</p>
