Simulations were performed by the GEOS-Chem CTM for 2017 (see “Methods” section for model details). Reconciling the model deposition velocities using our experimentally-obtained vd, and assuming that 100% of dry deposited MVK and 50% of dry deposited 1,2-ISOPOOH undergoes conversion in plants, reveals a global MEK source of 6.5 Tg yr−1 (and recycling 1.5% of the isoprene flux).
