Organic aerosol and global climate modelling: a review
The present paper reviews existing knowledge with regard to Organic Aerosol (OA) of importance for global climate modelling and defines critical gaps needed to reduce the involved uncertainties. AllExpand

High concentrations and photochemical fate of oxygenated hydrocarbons in the global troposphere
OXYGENATED species in the atmosphere are important sources of free radicals and are intricately linked with the fate of nitrogen oxides (NO x ), which are themselves necessary for tropospheric ozoneExpand

Tropospheric aerosol ionic composition in the Eastern Mediterranean region
Concentrations of the major soluble ions: sulfate (SO 4 = ), nitrate (NO 3 − ), chloride (Cl − ), methanesulfonate (MSA), sodium (Na + ), ammonium (NH 4 + )), potassium (K + ), calcium (Ca ++ ) andExpand

Organic aerosols in Eastern Mediterranean: components source reconciliation by using molecular markers and atmospheric back trajectories
Molecular markers, such as n-alkanes, hopanes, PAHs, n-alkanols, n-alkanals, n-alkan-2-ones and n-alkanoic acids, and atmospheric back trajectories have been conjointly used to reconcile EasternExpand

Global modelling of secondary organic aerosol in the troposphere: a sensitivity analysis
Abstract. A global 3-dimensional chemistry/transport model able to describe O 3 , NO x , Volatile Organic Compounds (VOC), sulphur and NH 3 chemistry has been extended to simulate the temporal andExpand

Acetone in the atmosphere: Distribution, sources, and sinks
Acetone (CH3COCH3) was found to be the dominant nonmethane organic species present in the atmosphere sampled primarily over eastern Canada (0–6 km, 35°–65°N) during ABLE3B (July to August 1990). AExpand

Secondary organic aerosol importance in the future atmosphere
In order to investigate the secondary organic aerosol (SOA) response to changes in biogenic volatile organic compounds (VOC) emissions in the future atmosphere and how important will SOA be relativeExpand

Tetrachloroethylene as an indicator of low Cl atom concentrations in the troposphere
Tetrachloroethylene (C2Cl4), a largely man-made chemical pollutant, is known to react with Cl atoms at a rate that is some 300 times faster than with OH radicals (kCl/kOH = 365 at 275 K). Analysis ofExpand
