TL;DR: In this paper, the authors compare the results of the early and late 1990s with 9 years of data of the Halogen Occultation Experiment (HALOE) on the Upper Atmosphere Research Satellite, some presented for the first time, and other satellite and radiosonde data.

TL;DR: In this article, a model analysis of the changes in atmospheric temperatures and the concentration of O3, OH and related gases between the three epochs is presented, showing that despite large changes in the atmospheric contents of CO2, CH4 and N2O, total ozone and tropospheric OH hardly changed between the glacial and pre-industrial holocene.

TL;DR: In this article, the kinetics of the reaction BrO + DMS → products were examined by use of pulsed-laser photolytic generation and time-resolved detection of the BrO radical by absorption spectroscopy.

TL;DR: In this paper, a chemical mechanism for heavy oxygen transfer from O3 to N2O was proposed, where the NOx-O3 photochemical interaction leads to the formation of NO2 with significant excess 17O. In a second step, the heavy oxygen anomaly is transferred to N 2O via the reaction NO 2 + NH 2? N 2 O + H 2 O, as part of the gas phase degradation of ammonia.

TL;DR: In this article, a Lagrangian-type model was used to compute the dynamics and microphysics of an orographical cloud formed in moist air flowing over the summit of Great Dun Fell (GDF) in England.
