Middle Stratospheric Polar Vortex Ozone Budget during the Warming Arctic Winter, 2002--2003

The ozone budget inside the middle stratospheric polar vortex (24-36 km) during the 2002-2003 Arctic winter is studied by analyzing Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) satellite data.A comprehensive global chemical transport model (Model for Ozone and Related Chemical Tracers,MOZART-3) is used to analyze the observed variation in polar vortex ozone during the stratospheric sudden warming (SSW) events.Both MIPAS measurement and MOZART-3 calculation show that a pronounced increas...
