Abstract The maintenance of large concentrations of active chlorine in Antarctic spring allows strong chemical ozone destruction to occur. In the lower stratosphere (approximately 16–18 km, 85–55 hPa, 390–430 K) in the core of the polar vortex, high levels of active chlorine are maintained, although rapid gas-phase production of HCl occurs. The maintenance is achieved through HCl null cycles in which the HCl production is balanced by immediate reactivation. The chemistry of the methyl peroxy… 
Mechanism of ozone loss under enhanced water vapour conditions in the mid-latitude lower stratosphere in summer
Abstract. Water vapour convectively injected into the mid-latitude lowermost stratosphere could affect stratospheric ozone. The associated potential ozone loss process requires low temperatures
Evaluation of the Potentiality of Chlorine in the Destruction of Ozone in Nigeria
Global warming is one of the major challenges in Nigeria. This is caused by the incessant release of depleting substances such as CFC; chlorofluorocarbon, BFC; Bromofluorocarbon, HCFC;

On the relevance of the methane oxidation cycle to ozone hole chemistry
The influence of the methane oxidation cycle on 'ozone hole' chemistry through its effect on HOx and ClOx radicals is focused on and it is demonstrated the great potential importance of the heterogeneous reaction HCl + HOCl yields Cl2 + H2O and the gasphase reaction ClO + CH3O2 yields ClOO +CH3O under sunlight conditions in polar spring.
The maintenance of elevated active chlorine levels in the Antarctic lower stratosphere through HCl null cycles
Abstract. The Antarctic ozone hole arises from ozone destruction driven by elevated levels of ozone destroying ( active ) chlorine in Antarctic spring. These elevated levels of active chlorine have
Free Radicals Within the Antarctic Vortex: The Role of CFCs in Antarctic Ozone Loss
Recent advances in understanding of the kinetics, photochemistry, and structural details of key intermediates in these catalytic cycles as well as an improved absolute calibration for ClO and BrO concentrations at the temperatures and pressures encountered in the lower antarctic stratosphere have been essential for defining the link.
Chlorine chemistry and the potential for ozone depletion in the Arctic stratosphere in the winter of 1991/92
We present an analysis of chlorine chemistry in the Arctic stratosphere during the winter of 1991/92 and assess its potential implications for ozone depletion. In accordance with observations of

THE direct reaction of HOC1 with HC1, known to occur in liquid water1 and on glass surfaces2, has now been measured on surfaces similar to polar stratospheric clouds3,4 and is shown here to play a
A quantitative analysis of the reactions involved in stratospheric ozone depletion in the polar vortex core
Abstract. We present a quantitative analysis of the chemical reactions involved in polar ozone depletion in the stratosphere and of the relevant reaction pathways and cycles. While the reactions
Halogen‐catalyzed methane oxidation
This paper highlights the importance of halogen-catalyzed methane oxidation in the upper troposphere and lower stratosphere. The calculated rate of methane oxidation is increased by at least 20% in
High concentrations and photochemical fate of oxygenated hydrocarbons in the global troposphere
OXYGENATED species in the atmosphere are important sources of free radicals and are intricately linked with the fate of nitrogen oxides (NO x ), which are themselves necessary for tropospheric ozone
Re‐formation of chlorine reservoirs in southern hemisphere polar spring
This paper focuses on the recovery of chlorine reservoir species in the lower stratosphere in late Antarctic spring. The investigations are based on measurements from the Halogen Occultation
Temperature thresholds for chlorine activation and ozone loss in the polar stratosphere
Abstract. Low stratospheric temperatures are known to be responsible for heterogeneous chlorine activation that leads to polar ozone depletion. Here, we discuss the temperature threshold below which
