TL;DR: In this paper, five organic aerosols (OA) components are identified using positive matrix factorization including hydrocarbon-like OA (HOA) and two types of oxygenated OA(OOA) components, and the Pasadena OA elemental composition when plotted as H:C versus O:C follows a line less steep than that observed for Riverside, CA.

TL;DR: In this article, four different literature parameterizations for the formation and evolution of urban secondary organic aerosol (SOA) frequently used in 3D models are evaluated using a 0-D box model representing the Los Angeles metropolitan region during the California Research at the Nexus of Air Quality and Climate Change (CalNex) 2010 campaign.

TL;DR: In this paper, the authors used in situ CO2, CO, and planetary boundary layer height (PBLH) measurements recorded during the CalNex-LA ground campaign of 15 May-15 June 2010, in Pasadena, CA, to deduce the diurnally varying anthropogenic component of observed CO2 in the megacity of Los Angeles (LA).

TL;DR: In this paper, the laser-induced fluorescence-fluorescence assay by gas expansion technique was used to measure hydroxyl (OH) and hydroperoxy (HO2*) radical concentrations at the Pasadena ground site during the CalNex-LA 2010 campaign.
