Abstract

The MIPAS infrared limb scanner instrument aboard ENVISAT has provided detailed information on the distribution of minor species in the stratosphere. We highligh of studies that we carried with the retrievals provided by ESA over the years 2002-2004, and focus on two topics. First, we examined how MIPAS observations revealed outstanding and long-lasting impacts of the Halloween 2003 solar storms on the nitrogen chemistry in the upper and middle stratosphere. We examine in particular the HNO3 and NO2 enhancements in the months following solar storms and geomagnetic perturbations. Second, we also show new results on the poorly-studied high-latitude stratosphere in the summer, as observed by MIPAS in 2003. We focus on the Arctic low-ozone pool, and its meridional displacements.
