Impact of ozone layer depletion I: ozone depletion climatology

Atmospheric Environment, 2001
Abstract A monthly ozone profile depletion climatology is constructed for the time period 11/1978–4/1993 for 10° latitude bands using the TOMS total ozone data and SAGE trends. Monthly mean Nimbus-7/TOMS total ozone data are analysed by multiple linear regression which takes into account the seasonal variation, quasi-biennial oscillations (QBO ...

Ozone-depleting substances

2012
In 1996 DG Environment announced plans to push for a radical reduction and phase-out of the most powerful short-term ozone-depleting substances, methyl bromide and HCFCs, as soon as possible. By proposing new phase out schedules for the two substances that went beyond internationally set targets of the 1987 Montreal Protocol, EU Environment ...

Stratospheric Ozone Depletion

2015
The stratospheric ozone layer plays a critical role in regulating conditions on Earth, but has been substantially depleted by CFC (chlorofluorocarbon) and other halocarbon emissions. This has increased transmission of UVB radiation to the surface, and been implicated in a range of negative human and ecosystem health impacts.
