Resumen:
ESTE LIBRO ES UNA ACTUALIZACION DE LA SITUACION DE LA CAPA DE OZONO Y SIRVE COMO BASE PARA QUE LOS TOMADORES DE DECISIONES DE PAISES DE TODO EL MUNDO LLEVEN A CABO LAS MEDIDAS NECESARIAS PARA LA RECUPERACION Y PRESERVACION DE LA CAPA DE OZONO. LO CUAL NO SOLO AFECTA A LA CAPA DE OZONO, SINO, TAMBIEN AL CAMBIO CLIMATICO. ESTOS INFORMES SE REALIZAN POR MANDATO DEL PROTOCOLO DE MONTREAL (1987) Y SE REALIZAN GENERALMENTE CADA 4 AÑOS.  EL PROCESO DE ELABORACION DEL MISMO LLEVA MAS DE 2 AÑOS. CADA CAPITULO PASA POR PROCESO DE REVISION POR PARTE DE CIENTIFICOS DE TODO EL MUNOD EN 3 ETAPAS DE SU ELABORACION, SEGUN SE CONSIGNA EN EL INFORME. LA AUTORIA DE LOS CAPITULOS ES POR INVITACION, REALIZADA POR LA ORGANIZACION METEOROLOGICA MUNDIAL Y EL PROGRAMA DE NACIONES UNIDAS PARA EL MEDIO AMBIENTE. EXCEPTO POR LOS "COORDINATING LEAD AUTHORS" (A. Douglass y V. Fioletov ) Y LOS "LEAD AUTHORS" ( S. Godin-Beekmann, R. Müller, R.S. Stolarski, A. Webb), LOS AUTORES ESTAN UBICADOS POR ORDEN ALFABETICO. Sólo se consignaron los nombre de los autores hasta el investigador al que pertenece esta producción científica, como autor número 15 se consignó “et al”. The first drafts of the chapters were examined at a meeting that occurred on 17–19 November 2009 in Fairfax, Virginia, United States, at which the Coordinating Lead Authors, Cochairs, and a small group of international experts focused on the scientific content of the draft chapters. The second drafts of the chapters were reviewed by 122 scientists worldwide in a mail peer review. Those comments were considered by the authors. At a Panel Review Meeting in Les Diablerets, Switzerland, held on 28 June–2 July 2010, the responses to these mail review comments were proposed by the authors and discussed by the 74 participants. Final changes to the chapters were decided upon at this meeting. 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 protection of the stratospheric ozone layer. . To meet this request, the Scientific Assessment Panel prepared, about every 3-4 years, major assessment reports that updated the state of understanding  and its purviews. These reports are prepared by the world’s leading experts in the atmospheric sciences and under the international auspices of the World Meteorological Organization (WMO) and/or the United Nations Environment Programme UNEP). The formal planning of the current assessment was started early in 2009. The Cochairs considered suggestions from the Parties regarding experts from their countries who could participate in the process. Furthermore, an ad hoc international scientific advisory group also suggested participants from the world scientific community. The first drafts of the chapters were examined at a meeting that occurred on 17–19 November 2009 in Fairfax, Virginia, United States, at which the Coordinating Lead Authors, Cochairs, and a small group of international experts focused on the scientific content of the draft chapters. The second drafts of the chapters were reviewed by 122 scientists worldwide in a mail peer review. Those comments were considered by the authors. At a Panel Review Meeting in Les Diablerets, Switzerland, held on 28 June–2 July 2010, the responses to these mail review comments were proposed by the authors and discussed by the 74 participants. Final changes to the chapters were decided upon at this meeting. This chapter presents information on several topics but is conceptually organized around a single question: is the Montreal Protocol working? This chapter is focused on the observational record and interpretation thereof up to the present, and consolidates information found in three separate chapters in the previous Assessment, 2007: Chapter 3: “Global Ozone: Past and Present”, Chapter 4: “Polar Ozone: Past and Present”  and Chapter 7: “Surface Ultraviolet Radiation: Past, Present and Future”. There are four sections in this chapter: Ozone Observations, Polar Ozone, Surface Ultraviolet Radiation, and Interpretation of Observed Ozone Changes. Each section begins with a summary of WMO (2007) followed by a combination of updates to the observational records and longer discussion of new discoveries and observations.
