Short summary

We assess and quantify the ozone loss driven by NO_x, triggered by stratospheric warmings and the halogens-induced ozone loss, using data assimilation results over a decade. To illustrate the difference between halogen-induced loss and NO_x-induced loss, we compared a relatively cold and stable winter (2010/2011) with a composite calculation of four winters (2003/2004, 2005/2006, 2008/2009 and 2012/2013) which were all affected by a major mid-winter sudden stratospheric warming event.
