Reactive processing of formaldehyde and acetaldehyde in aqueous aerosol mimics: Surface tension depression and secondary organic products
Surface tension depression and secondary organic products aqueous aerosol mimics
2011/6/15
The reactive uptake of carbonyl-containing volatile organic compounds (cVOCs) by aqueous atmospheric aerosols is a likely source of particulate organic material. The aque ous-phase secondary organic p...
Global atmospheric budget of acetaldehyde: 3-D model analysis and constraints from in-situ and satellite observations
Global atmospheric budget acetaldehyde 3-D model analysis and constraints in-situ and satellite observations
2010/4/12
We construct a global atmospheric budget for acetaldehyde using a 3-D model of atmospheric chemistry (GEOS-Chem), and use an ensemble of observations to evaluate present understanding of its sources a...
Acetaldehyde is a reactive intermediate in hydrocarbon oxidation. It is both emitted and taken up by snowpacks and photochemical and physical processes are probably involved. Understanding the reactiv...
Sources and sinks of acetone, methanol, and acetaldehyde in North Atlantic marine air

2009/2/12
Measurements of acetone, methanol, acetaldehyde and a range of non-methane hydrocarbons have been made in North Atlantic marine air at the Mace Head observatory. Under maritime conditions the combina...
Air-sea fluxes of methanol, acetone, acetaldehyde, isoprene and DMS from a Norwegian fjord following a phytoplankton bloom in a mesocosm experiment
