TL;DR: In this paper, the authors used observations from the Cheeka Peak Observatory in northwestern Washington State during March-April, 1997, to show that Asian anthropogenic emissions significantly impact the concentrations of a large number of atmospheric species in the air arriving to North America during spring.

TL;DR: Airborne measurements in smoke from biomass burning in Brazil have yielded optical parameters that permit an improved assessment of the effects of smoke on Earth's radiation balance, and direct radiative forcing due to smoke can be large and might indirectly affect global climate.

TL;DR: The light-scattering coefficients of aerosols as a function of relative humidity (RH) and wavelength were measured in flights off the mid-Atlantic coast of the United States during July 1996 as discussed by the authors.

TL;DR: In this article, the light scattering coefficient of aerosols from biomass burning was measured as a function of relative humidity (RH) and wavelength in four regions of Brazil extending from the cerrado to the primary forests of the Amazon Basin.

TL;DR: In this article, the ozone photochemical tendency, T(O3), in the Eastern North Pacific atmosphere (PHOBEA) was calculated by using a photochemical box model, and the model was used to investigate the impacts of PAN decomposition on the mixing ratio of NOx (defined here as NO+NO2+NO3+2N2O5+ HNO2 +HNO4).
