Emission location dependent ozone depletion potentials for very short-lived halogenated species
Emission location ozone depletion potentials short-lived halogenated species
2010/12/28
We present trajectory-based estimates of Ozone Depletion Potentials (ODPs) for very short-lived halogenated source gases as a function of surface emission location. The ODPs are determined by the frac...
Atmospheric lifetimes and Ozone Depletion Potentials of trans-1-chloro-3,3,3-trifluoropropylene and trans-1,2-dichloroethylene in a three-dimensional model
Atmospheric lifetimes and Ozone Depletion trans-1-chloro-3,3,3-trifluoropropylene trans-1,2-dichloroethylene a three-dimensional model
2010/11/30
The chloroalkenes trans-1-chloro-3,3,3-trifluoropropylene (tCFP) and trans-1,2-dichloroethylene (tDCE) have been proposed as candidate replacements for other compounds in current use that cause concer...
Will climate change increase ozone depletion from low-energy-electron precipitation?
climate change ozone depletion low-energy-electron precipitation
2010/10/21
We investigate the effects of a strengthened stratospheric/mesospheric residual circulation on the transport of nitric oxide (NO) produced by energetic particle precipitation. During periods of high g...
Vertical structure of Antarctic tropospheric ozone depletion events: characteristics and broader implications
Vertical structure Antarctic tropospheric ozone depletion events characteristics and broader implications
2010/8/25
The majority of tropospheric ozone depletion event (ODE) studies have focussed on time-series measurements, with comparatively few studies of the vertical component. Those that exist have almost exclu...
Introducing the bromide/alkalinity ratio for a follow-up discussion on "Precipitation of salts in freezing seawater and ozone depletion events: a status report", by Morin et al., published in Atmos. Chem. Phys., 8, 7317–7324, 2008
the bromide/alkalinity ratio freezing seawater ozone depletion events salts
2010/8/25
Sander et al. (2006) proposed that CaCO3 precipitation can be an important factor in triggering tropospheric ozone depletion events. Recently, Morin et al. (2008b) presented calculations with the FREZ...
BrO, blizzards, and drivers of polar tropospheric ozone depletion events
BrO blizzards polar tropospheric ozone depletion events
2009/7/23
The source of bromine that drives polar boundary layer ozone depletion events (ODEs) is still open to some debate. While ODEs are generally noted to form under conditions of a shallow stable boundary ...

Surface ozone depletion episodes in the Arctic and Antarctic from historical ozonesonde records
Surface ozone depletion episodes Arctic Antarctic historical ozonesonde
2009/3/12
Episodes of ozone depletion in the lowermost Arctic atmosphere (0--2 km) at polar sunrise have been intensively studied at Alert, Canada, and are thought to result from catalytic reactions involving b...
Investigation of Arctic ozone depletion sampled over midlatitudes during the Egrett campaign of spring/summer 2000
Arctic ozone depletion midlatitudes Egrett campaign
2009/3/4
A unique halocarbon dataset has been obtained using the Australian high altitude research aircraft, the Grob G520T Egrett, during May-June 2000 with GC instrument (DIRAC), which has been previously de...
An assimilated data base of total column ozone measurements from satellites has been used to generate a set of indicators describing attributes of the Antarctic ozone hole for the period 1979 to 2003,...
Vortex-averaged Arctic ozone depletion in the winter 2002/2003
Vortex-averaged Arctic ozone depletion winter SAOZ data
2009/1/23
A total ozone depletion of 68±7 Dobson units between 380 and 525K from 10 December 2002 to 10 March 2003 is derived from ozone sonde data by the vortex-average method, taking into account both diabati...
Carbonate precipitation in brine – a potential trigger for tropospheric ozone depletion events
Carbonate precipitation potential trigger tropospheric ozone depletion events
2009/1/16
Tropospheric ozone depletion events (ODEs) at high latitudes were discovered 20 years ago and are attributed to bromine explosions. However, an unresolved issue is the explanation of how the acid-cata...
UV radiation below an Arctic vortex with severe ozone depletion
UV radiation Arctic vortex ozone depletion
2009/1/14
The erythemally weighted (UV) irradiance below the severely depleted Arctic vortices in spring 1996 and 1997 were substantially elevated. On average the UV increased 36 and 33% relative to the 1979-19...
The influence of polar vortex ozone depletion on NH mid-latitude ozone trends in 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...
