Quantify the abundance of isoprene oxidation products in gas and aerosol phases and evaluate their global contribution to atmospheric aerosol organic matter.
Measured gas- and aerosol-phase glycolaldehyde, hydroxyacetone, and methylglyoxal across two field experiments using an annular denuder sampling system.
Predicted global aerosol mass distribution using field data, chemical box modeling, and humidity-dependent gas-phase simulations from a global 3-D atmospheric model.
Isoprene oxidation contributes an estimated 35 Tg of aerosol organic matter annually to the global atmosphere, with an estimated range of 10 to 120 Tg.
