Fig. 1. Annual average sources and sinks of acetaldehyde in GEOS-Chem. Shown are photochemical production, biogenic emis- emis-sions from live and decaying plants, anthropogenic emisemis-sions (urban/industrial + biofuel), biomass burning emisemis-sions, p
Fig. 2. Annual average sources and sinks of ethanol in GEOS-Chem. Shown are photochemical production, biogenic emissions from live and decaying plants, anthropogenic emissions (urban/industrial + biofuel), biomass burning emissions, photochemical loss, and
Fig. 3. Cumulative molar yield of acetaldehyde from the oxida- oxida-tion of VOCs. Yields are computed using the GEOS-Chem (red) and MCMv3.1 (black) chemical mechanisms, for 1 ppb NO x (solid lines) and 0.1 ppb NO x (dashed lines).
Fig. 5. Acetaldehyde photoproduction in the ocean mixed layer averaged by season. Photoproduction rates are estimated from colored dissolved organic matter absorption fields derived from SeaWiFS satellite observations as described in the text.
