Missing Peroxy Radical Sources within a Summertime Ponderosa Pine Forest
Organic peroxy (RO2) and hydroperoxy (HO2) radicals are key intermediates in the photochemical processes that generate ozone, secondary organic aerosol and reactive nitrogen reservoirs throughout the troposphere. In regions with ample biogenic hydrocarbons, the richness and complexity of peroxy radical chemistry presents a significant challenge to current-generation models, especially given the...
متن کاملMissing Peroxy Radical Sources within a Rural Forest Canopy
REFEREE 1 The manuscript “Missing peroxy radical sources within a rural forest canopy” by Wolfe et al 2014 presents a solid and unique set of measurements within a Ponderosa Pine forest. The main focus of this paper is the observation and analysis of peroxy radicals. Therefore various gas chemical measurements were utilized to run a box model and compare the modeled diel cycle to the observatio...
متن کاملUnderstanding in situ ozone production in the summertime through radical observations and modelling studies during the Clean air for London project (ClearfLo)
Measurements of OH, HO2, RO2i (alkene and aromatic related RO2) and total RO2 radicals taken during the ClearfLo campaign in central London in the summer of 2012 are presented. A photostationary steady-state calculation of OH which considered measured OH reactivity as the OH sink term and the measured OH sources (of which HO2+NO reaction and HONO photolysis dominated) compared well with the obs...
متن کاملClosing the peroxy acetyl nitrate budget: observations of acyl peroxy nitrates (PAN, PPN, and MPAN) during BEARPEX 2007
Acyl peroxy nitrates (APNs, also known as PANs) are formed from the oxidation of aldehydes and other oxygenated VOC (oVOC) in the presence of NO2. There are both anthropogenic and biogenic oVOC precursors to APNs, but a detailed evaluation of this chemistry against observations has proven elusive. Here we describe measurements of PAN, PPN, and MPAN along with the majority of chemicals that part...
متن کاملIsoprene Peroxy Radical Dynamics.
Approximately 500 Tg of 2-methyl-1,3-butadiene (isoprene) is emitted by deciduous trees each year. Isoprene oxidation in the atmosphere is initiated primarily by addition of hydroxyl radicals (OH) to C4 or C1 in a ratio 0.57 ± 0.03 (1σ) to produce two sets of distinct allylic radicals. Oxygen (O2) adds to these allylic radicals either δ (Z or E depending on whether the allylic radical is cis or...
