GORMP, 58. Scientific Assessment of Ozone Depletion: 2018
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.Quel est l’état de la couche d’ozone?: Le point sur l’évaluation la plus récente eff ectuée par l’OMM/PNUE
Bulletin, Vol. 64(1). OMM, 2016L’évaluation de l’état de la couche d’ozone réalisée en 2014, la plus récente en date, établit des prévisions concernant le retour aux valeurs d’avant 1980. Sous les latitudes moyennes de l’hémisphère Nord (35-60°N), la concentration d’ozone total est aujourd’hui inférieure d’environ 3,5 % à ce qu’elle était pendant la période 1964-1980. Sous les latitudes moyennes de l’hémisphère Sud (35-60°S), elle est inférieure de 6 % environ. La déperdition plus importante observée dans l’hémisphère Sud est liée au trou qui se forme dans la couche d’ozone au-dessus de l’Antarctique. Après la baisse du tau ...SatFC-G: IR Bands, Excluding Water Vapor
This lesson introduces seven of the ten infrared imager bands on the GOES R-U ABI (Advanced Baseline Imager). It examines the spectral characteristics of each band to facilitate a better understanding of band selection and what each band observes, and to shed light on some of the many potential applications. This lesson is a part of the NWS Satellite Foundation GOES-R Course.Vol. 53 No. 1 - February/ Février 2015 - Special issue: Proceedings of the Twenty-Second Quadrennial Ozone Symposium = Numéro spécial: Comptes-rendus du vingt-deuxième Symposium quadriennal sur l'ozone
is an issue of Atmosphere-ocean. Canadian Meteorological and Oceanographic Society, 2015Is the Ozone Layer on the Mend? Highlights from the most recent WMO/UNEP Ozone Assessment
Bulletin, Vol. 64(1). WMO, 2015The 2014 Ozone Assessment provides the latest update of the current state of the ozone layer and makes predictions on when the ozone layer will return to 1980 values. In the northern middle latitudes (35-60°N), total ozone is now about 3.5% less than it was in the period from 1964-1980. At southern middle latitudes (35-60°S), it is about 6% less. The larger depletion in the Southern Hemisphere is linked to the Antarctic ozone hole. Following the decline in total ozone during the 1980s and 1990s, the situation has stabilized since 2000. Hidden under the inter-annual variability, there are indic ...
Twenty 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 ...
GORMP, 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.

WMO, 2014GOES-R ABI: Next Generation Satellite Imaging
This extension of the COMET lesson “GOES-R: Benefits of Next Generation Environmental Monitoring” focuses on the ABI instrument, the satellite's 16-channel imager. With increased spectral coverage, greater spatial resolution, more frequent imaging, and improved image pixel geolocation and radiometric performance, the ABI will bring significant advancements to forecasting, numerical weather prediction, and climate and environmental monitoring. The first part of the lesson introduces the ABI's key features and improvements over earlier GOES imagers. The second section lets users interactively ex ...Ozone-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 – SUMMARY
