The potential impact of ClOx radical complexes on polar stratospheric ozone loss processes
ClOx radical complexes polar stratospheric ozone
2009/1/13
The importance of radical-molecule complexes for atmospheric chemistry has been discussed in recent years. In particular, the existence of a ClO·O2 and ClOx water radical complexes like ClO·H2O, OClO·...
The influence of polar vortex ozone depletion on NH mid-latitude ozone trends in spring
polar vortex ozone depletion NH mid-latitude ozone spring
2009/1/13
Reverse domain-filling trajectory calculations have been performed for the years 1993, 1995, 1996, 1997, and 2000 to calculate the spreading of ozone depleted air from the polar vortex to midlatitudes...
Chemical ozone loss in the Arctic winter 2002/2003 determined with Match
Chemical ozone loss Arctic winter
2009/1/13
The Match technique was used to determine chemically induced ozone loss inside the stratospheric vortex during the Arctic winter 2002/2003. From end of November 2002, which is the earliest start of a ...
Retrieval of stratospheric ozone profiles from MIPAS/ENVISAT limb emission spectra: a sensitivity study
stratospheric ozone profiles MIPAS/ENVISAT limb emission spectra sensitivity
2009/1/13
We report on the dependence of ozone volume mixing ratio profiles, retrieved from limb emission infrared spectra of the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS), on different ...
Ozone observations by the Gas and Aerosol Measurement Sensor during SOLVE II
Ozone Gas and Aerosol Measurement Sensor SOLVE II
2009/1/12
The Gas and Aerosol Measurement Sensor (GAMS) was deployed aboard the NASA DC-8 aircraft during the second SAGE III Ozone Loss and Validation Experiment (SOLVE II). GAMS acquired line-of-sight (LOS) d...
Kinetics and mechanism of heterogeneous oxidation of sulfur dioxide by ozone on surface of calcium carbonate
Kinetics and mechanism heterogeneous oxidation sulfur dioxide calcium carbonate
2009/1/12
Sulfate particles play a key role in the air quality and the global climate, but the heterogeneous formation mechanism of sulfates on surfaces of atmospheric particles is not well established. Carbona...
Detection and measurement of total ozone from stellar spectra: Paper 2. Historic data from 1935–1942
total ozone stellar spectra
2009/1/9
Atmospheric ozone columns are derived from historic stellar spectra observed between 1935 and 1942 at Mount Wilson Observatory, California. Comparisons with contemporary measurements in the Arosa data...
Peroxy radical chemistry and the control of ozone photochemistry at Mace Head, Ireland during the summer of 2002
Peroxy radical chemistry control of ozone photochemistry Mace Head

Peroxy radical (HO2+ΣRO2) measurements, using the PEroxy Radical Chemical Amplification (PERCA) technique at the North Atlantic Marine Boundary Layer EXperiment (NAMBLEX) at Mace Head in summer 2002, ...
Sensitivity analysis by the adjoint chemistry transport model DRAIS for an episode in the Berlin Ozone（BERLIOZ）experiment
adjoint chemistry transport model DRAIS BERLIOZ
2009/1/9
The Berlin Ozone Experiment (BERLIOZ) was carried out in summer 1998. One of its purposes was the evaluation of Chemistry Transport Models (CTM). CTM KAMM/DRAIS was one of the models considered. The d...
