Three‐dimensional chemical model simulations of the ozone layer: 2015–55
Abstract A stratospheric‐chemistry model coupled to a general‐circulation model is used to investigate chemistry‐climate coupling processes and their influence on ozone. Simulations commence on 1 March in each of the years 2014, 2024, 2034, 2044 and 2054, and consist of a 4‐month spin‐up period, fol...
