Anthropogenic emissions and land use changes have modified atmospheric aerosol
concentrations and size distributions over time. Understanding preindustrial conditions and …

Isoprene carries approximately half of the flux of non-methane volatile organic carbon
emitted to the atmosphere by the biosphere. Accurate representation of its oxidation rate and …

Oxidation of biogenic volatile organic compounds (BVOC) by the nitrate radical (NO 3)
represents one of the important interactions between anthropogenic emissions related to …

The nitrate radical, NO3, is photochemically unstable but is one of the most chemically
important species in the nocturnal atmosphere. It is accompanied by the presence of …

Isoprene emitted by vegetation is an important precursor of secondary organic aerosol
(SOA), but the mechanism and yields are uncertain. Aerosol is prevailingly aqueous under …

Light absorption of fine particle (PM 2.5) aqueous extracts between wavelengths of 200 and
800 nm were investigated from two data sets: 24-h Federal Reference Method (FRM) filter …

In the atmosphere nighttime removal of volatile organic compounds is initiated to a large
extent by reaction with the nitrate radical (NO3) forming organic nitrates which partition …

Formation of organic nitrates (RONO 2) during oxidation of biogenic volatile organic
compounds (BVOCs: isoprene, monoterpenes) is a significant loss pathway for atmospheric …

Laboratory studies have established a number of chemical pathways by which nitrogen
oxides (NO x) affect atmospheric organic aerosol (OA) production. However, these effects …

We implement a new isoprene oxidation mechanism in a global 3‐D chemical transport
model (GEOS‐Chem). Model results are evaluated with observations for ozone, isoprene …
