TL;DR: In this paper, the authors investigated the physical and chemical evolution of biomass burning (BB) organic aerosols (POA and SOA) using the Aerodyne Aerosol Mass Spectrometer.

TL;DR: In this article, the atmospheric lifetime of methanol in the model is 7 days; gas-phase oxidation by OH accounts for 63% of the global sink, dry deposition to land 26%, wet deposition 6%, uptake by the ocean 5%, and aqueous phase oxidation in clouds less than 1%.

TL;DR: Quantitative product analysis confirms that squalene is the major scavenger of ozone at the interface between room air and the human envelope, and reactions between ozone and human skin lipids reduce the mixing ratio of ozone in indoor air, but concomitantly increase the mixing ratios of volatile products and, presumably, skin surface concentrations of less volatile products.

TL;DR: In this article, the authors determined enhancement ratios for NOx, PAN, and other NOy species from boreal biomass burning using aircraft data obtained during the ARCTAS-B campaign and examined the impact of these emissions on tropospheric ozone in the Arctic.
