Abstract

Although designed primarily for observation of the stratosphere, MIPAS provides a wealth of valuable data on the upper troposphere and lowermost stratosphere (UTLS). Processes in the UTLS relevant to chemistry-climate coupling and observed by MIPAS include the distribution of greenhouse gases in the troposphere, transport of water vapour through the (tropical) tropopause, stratosphere/troposphere exchange in the extra-tropics, biomass burning and long-range transport of pollutants in the upper troposphere, and chemical processes in the TTL. Examples for episodes representing such processes have been analysed on basis of distributions of trace gases retrieved from MIPAS spectral data with the scientific processor at IMK/IAA. In particular these are UTLS water vapour, HDO, ozone, HNO3, CFCs, SF6, CH4, N2O, CO, PAN, C2H6, clouds, and temperature. In this contribution, an overview will be given on the scientific MIPAS results related to UTLS.
