Attribution of observed changes in stratospheric ozone and temperature
Three recently-completed sets of simulations of multiple chemistry-climate models with greenhouse gases only, with all anthropogenic forcings, and with anthropogenic and natural forcings, allow the causes of observed stratospheric changes to be quantitatively assessed using detection and attribution techniques. The total column ozone response to halogenated ozone depleting substances and to nat...
متن کاملThe 2010 Antarctic ozone hole: Observed reduction in ozone destruction by minor sudden stratospheric warmings
Satellite observations show that the 2010 Antarctic ozone hole is characterized by anomalously small amounts of photochemical ozone destruction (40-60% less than the 2005-2009 average). Observations from the MLS instrument show that this is mainly related to reduced photochemical ozone destruction between 20-25 km altitude. Lower down between 15-20 km the atmospheric chemical composition and ph...
متن کاملTwenty-two years observations of stratospheric ozone concentration, temperature and aerosol over Tsukuba, Japan
Differential absorption lidar (DIAL) at the National Institute for Environmental Studies (NIES) in Tsukuba (36°N, 140°E), Japan has been making routine observation for almost 22 years. Since 1988, more than 650 vertical profiles of stratospheric ozone and temperature have been obtained. We compared the lidar data with satellite data from the Stratospheric Aerosol and Gas Experiment (SAGE II) an...
متن کاملSolar proton event: influence on stratospheric ozone.
Large-scale reductions in the ozone content of the middle and upper stratosphere over the polar cap regions were associated with the major solar proton event of 4 August 1972. This reduction, which was determined from measurements with the backscattered ultraviolet experiment on the Nimbus 4 satellite, is interpreted as being due to the catalytic destruction of ozone by odd-nitrogen compounds (...
متن کاملthe synoptic analysis of ozone mini-hole events over central iran (esfahan)
in this study, the daily total ozone column (toc) measured by the instruments of toms (2001) and omi (2005-2011) satellites and brewer ground station (2002-2004) is used to investigate the extreme ozone mini-holes over esfahan. based on previous reports on validation of the toc data products, it is found that there is no problem with homogenization of data records, which was provided by the abo...
