Journal ArticleDOI
Photochemical processing of aqueous atmospheric brown carbon
TL;DR: In this paper, a series of laboratory studies of photochemical processing of aerosol brown carbon in the aqueous phase, by direct photolysis and OH oxidation, was reported. And the results indicated that atmospheric models need to incorporate representations of atmospheric processing of BrC species to accurately model their radiative impacts.
Journal ArticleDOI
Formation of light absorbing organo-nitrogen species from evaporation of droplets containing glyoxal and ammonium sulfate.
TL;DR: In this paper, the formation of organo-nitrogen and light absorbing materials in evaporating droplets containing glyoxal and different ammonium salts including (NH4)2SO4, NH4NO3, and NH4Cl were investigated.
Journal ArticleDOI
Aqueous-phase photooxidation of levoglucosan – a mechanistic study using aerosol time-of-flight chemical ionization mass spectrometry (Aerosol ToF-CIMS)
TL;DR: In this article, aqueous-phase photooxidation of Levoglucosan (LG) by hydroxyl (OH) radicals was performed in the laboratory and the reaction kinetics and products were monitored by aerosol time-of-flight chemical ionization mass spectrometry (Aerosol ToF-CIMS).
Journal ArticleDOI
Observations and impacts of bleach washing on indoor chlorine chemistry.
TL;DR: Photochemical box modeling indicates that the OH, Cl, and ClO gas-phase radical concentrations in the indoor environment could be greatly enhanced in such washing conditions, dependent on the amount of indoor illumination.
Journal ArticleDOI
Primary marine aerosol‐cloud interactions off the coast of California

TL;DR: In this article, a constrained lognormal-mode-fitting procedure was devised to isolate PMA number size distributions from total aerosol size distributions and applied to E-PEACE measurements.
