World Meteorological Organization (WMO) ; National Oceanic and Atmospheric Administration (NOAA); United Nations Environment Programme (UNEP); et al. - WMO, 2018The Assessment documents the advances in scientific understanding of ozone depletion reflecting the thinking of the many international scientific experts who have contributed to its preparation and review. These advances add to the scientific basis for decisions made by the Parties to the Montreal Protocol. It is based on longer observational records, new chemistry- climate model simulations, and new analyses.EnglishTwenty Questions and Answers about the Ozone Layer: 2014 update : Scientific Assessment of Ozone Depletion: 2014
World Meteorological Organization (WMO) ; National Oceanic and Atmospheric Administration (NOAA); United Nations Environment Programme (UNEP); et al. - WMO, 2015To help maintain a broad understanding of the relationship between ozone depletion, ODSs, and the Montreal Protocol, this component of the Scientific Assessment of Ozone Depletion: 2014 presents 20 questions and answers about the often-complex science of ozone depletion. Most questions and answers are updates of those presented in previous Ozone Assessments, and a few have been expanded to address newly emerging issues. The questions address the nature of atmospheric ozone, the chemicals that cause ozone deple tion, how global and polar ozone depletion occur, the extent of ozone depletion, the ...EnglishGORMP, 56. Assessment for Decision-Makers : scientific Assessment of Ozone Depletion
The present document will be part of the information upon which the Parties to the United Nations Montreal Protocol will base their future decisions regarding ozone-depleting substances, their alternatives, and protection of the ozone layer. It is the latest in a long series of scientific assessments that have informed the Parties.EnglishOzone-depleting substances 2012
EEA, 2013Aggregated data reported by companies on the import, export, production, destruction and feedstock and process agent use of ozone-depleting substances in the European Union – SUMMARYEnglishExtending ozone treaty would support GHG reduction goals
Science for Environment Policy, Issue 288. EEA, 2012Extending the Montreal Protocol on ozone-depleting substances to include hydrofluorocarbons (HFCs) could have important benefits for climate change action, say scientists in a recent analysis. HFCs are currently part of the Kyoto Protocol as greenhouse gases, but this protection will end with the expiry of Kyoto commitments this year.EnglishOzone-depleting substances 2011: summary
EEA, 2012Aggregated data reported by companies on the production, import, export, destruction and use of ozone-depleting substances in the European Union.EnglishAir & Climate: conversations about molecules and planets, with humans in between
European Commission, 2012This is a collection of conversations with some of the ‘fathers’ of air pollution and climate change science. Through careful observation and a mix of intuition and critical thought, they have uncovered some of the workings of our planet: its atmosphere and climate. They were generally driven by curiosity and gradually by a concern that mankind might indeed have a devastating impact on Earth and the life it hosts. Their findings were so important that they could not stay in the ivory tower of scientific research. They personally reached out to decision makers and the public at large because in ...EnglishNew ozone hole discovered over the Arctic
Science for Environment Policy, Issue 266. EEA, 2011For the first time, scientists have identified an 'ozone hole' over the Arctic, in addition to the well-known ozone hole over the Antarctic. Unusually persistent low temperatures over the Arctic in early 2011 caused an unprecedented amount of chemical destruction of stratospheric ozone there. The authors warn that this is likely to happen again, although it is presently difficult to predict when this might be.EnglishLeaked hydrogen fuel could have small negative effects on atmosphere
Science for Environment Policy, Issue 266. EEA, 2011Using hydrogen as an energy carrier can help reduce air pollution and greenhouse gas (GHG) emissions associated with fossil fuels, according to recent research. However, if used on a large-scale, it is important that hydrogen does not leak significantly into the atmosphere as it might have some negative environmental effects, such as increasing the lifetime of methane, increasing climate effects and causing some depletion of the ozone layer.EnglishMulti-scale modeling study of the source contributions to near-surface ozone and sulfur oxides levels over California during the ARCTAS-CARB period
Atmospheric Chemistry and Physics (ACP), Vol. 11. N° 7. Huang M.; Carmichael Gregory R.; Spak S. N.; et al. - Copernicus GmbH, 2011Chronic high surface ozone (O3) levels and the increasing sulfur oxides (SOx = SO2+SO4) ambient concentrations over South Coast (SC) and other areas of California (CA) are affected by both local emissions and long-range transport. In this paper, multi-scale tracer, full-chemistry and adjoint simulations using the STEM atmospheric chemistry model are conducted to assess the contribution of local emission sourcesto SC O3 and to evaluate the impacts of transported sulfur and local emissions on the SC sulfur budgetduring the ARCTAS-CARB experiment period in 2008. Sensitivity simulations quantify c ...EnglishThe Antarctic ozone hole during 2008 and 2009
Australian Meteorological and Oceanographic Journal (AMOJ), Vol. 61 No.1. Tully M.B.; Klekociuk A.R; Alexander S.P.; et al. - Australian Bureau of Meteorology, 2011The Antarctic ozone holes of 2008 and 2009 are reviewed from various perspectives, making use of a range of Australian data and analyses. In both years, ozone holes formed that were fairly typical of those observed since the late 1990s. The ozone hole of 2008 was somewhat larger than that of 2009. In 2009 the ozone hole developed more rapidly, but did not last as long as in 2008, particularly in the lower stratosphere.EnglishGORMP, 52.

Scientific Assessment of Ozone Depletion: 2010 - Executive summary
World Meteorological Organization (WMO) ; National Oceanic and Atmospheric Administration (NOAA); United Nations Environment Programme (UNEP); et al. - WMO, 2011It has been recognized since the 1970s that a number of compounds emitted by human activities deplete stratospheric ozone. The montreal Protocol on Substances that Deplete the Ozone layer was adopted in 1987 to protect global ozone and, consequently, protect life from increased ultraviolet (UV) radiation at Earth’s surface. Chlorine- and brominecontaining substances that are controlled by the montreal Protocol are known as ozone-depleting substances (ODSs).
ODSs are responsible for the depletion of stratospheric ozone observed in polar regions (for example, the “ozone hole” above An ...EnglishGORMP, 52. Scientific Assessment of Ozone Depletion: 2010
