Absorption measurements of oxygen between 330 and 1140 nm
TL;DR: The absorption spectrum of O2 and O2-O2 collision pairs were measured over the wavelength range from 330 to 1140 nm using pressures of O 2 from 1 to 55 atm at 298 K as mentioned in this paper.
Journal ArticleDOI
Bias in Filter-Based Aerosol Light Absorption Measurements Due to Organic Aerosol Loading: Evidence from Laboratory Measurements
TL;DR: In this article, light absorption by soot or nigrosin dye aerosol particles were measured in the laboratory using a particle soot absorption photometer (PSAP) and a photo-acoustic spectrometer (PAS) to assess the influence of nonabsorbing organic aerosol (OA) on the PSAP measurements.
Journal ArticleDOI
Measurement of hydroxyl and hydroperoxy radical uptake coefficients on water and sulfuric acid surfaces
TL;DR: In this paper, a wetted wall flow tube was used to measure the uptake coefficients, γ, of OH and HO 2 on pure water at 275 K and 28% w/w sulfuric acid at 249 K.
Journal ArticleDOI

TL;DR: In this paper, the photodissociation quantum yields for acetone in the 290-320 nm wavelength region for pressures and temperatures characteristic of the upper troposphere were compared with those obtained during the NASA and NOAA sponsored Stratospheric Tracers of Atmospheric Transport (STRAT) field campaign.
Journal ArticleDOI
Ozone depletion and global warming potentials of CF3I
TL;DR: In this paper, the lifetime of CF{sub 3}I in the sunlit atmosphere is less than a day, and the 20-year global warming potential (GWP) of this gas is likely to be very small, less than 5.
