Researchers performed direct measurements of the urban nonmethane volatile organic compound (NMVOC) flux into the atmosphere, and found that oxygenated compounds constituted an unexpectedly large proportion of the total flux that could not be accounted for by known photochemistry or bottom-up emission inventories, suggesting that current atmospheric chemistry and global climate models might underestimate global anthropogenic NMVOC emissions.
