A Common Representative Intermediates (CRI) mechanism for VOC degradation. Part 3: Development of a secondary organic aerosol module
TL;DR: In this article, a photochemical trajectory model with the Master Chemical Mechanism version 3.1 (MCM v3.1) coupled with an optimised representation of gas-aerosol absorptive partitioning of 365 oxygenated product species was used to simulate mass concentrations of secondary organic aerosol (SOA) for the conditions of the TORCH-2003 campaign in the south-east UK.

Kinetic studies of reactions of the nitrate radical (NO3) with peroxy radicals (RO2): an indirect source of OH at night?
S. Vaughan,Carlos E. Canosa-Mas,Christian Pfrang,Dudley E. Shallcross,L.A. Watson,Richard P. Wayne +5 more
TL;DR: A discharge-flow system, coupled to cavity-enhanced absorption spectroscopy (CEAS) detection systems for NO3 and NO2, was used to investigate the kinetics of the reactions of NO3 with eight peroxy radicals, and possible relationships between k and the orbital energies of the reactants are explored.

The potential impact of biogenic emissions of isoprene on urban chemistry in the United Kingdom
TL;DR: In this paper, a two-box atmospheric chemistry model was used to study the effect of biogenic isoprene emissions upon trace gas constituents in the urban troposphere, which was shown to lower OH and NOx and raise O3 and VOCs in summer.

Night‐time NO3 and OH radical concentrations in the United Kingdom inferred from hydrocarbon measurements
Mubarak A. Khan,M. J. Ashfold,Graham Nickless,Damien Martin,L.A. Watson,P. D. Hamer,Richard P. Wayne,Carlos E. Canosa-Mas,Dudley E. Shallcross +8 more
TL;DR: In this article, the authors used the hydrocarbon decay method (Rivett et al., 2003) to analyse hydrocarbon data from four contrasting sites in the United Kingdom to estimate night-time levels of NO3 and OH.
Estimation of Daytime NO3 Radical Levels in the UK Urban Atmosphere Using the Steady State Approximation Method
Mubarak A. Khan,W.C. Morris,L.A. Watson,M. Galloway,P. D. Hamer,Beth M. A. Shallcross,Carl J. Percival,Dudley E. Shallcross +7 more
TL;DR: In this article, the steady state approximation has been applied to the UK National Environment Technology Centre (NETCEN) data at three urban sites in the UK (Marylebone Road London, London Eltham, and Harwell) over the period of 1997 to 2012 to estimate the concentrations of daytime NO3.
