Abstract

The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) is a high-resolution limb sounder on board the ENVISAT satellite, successfully launched on March 1, 2002. MIPAS has a wide spectral coverage, high spectral resolution (0.035-0.0625 cm-1), and high sensitivity, which allows to measure most of atmospheric emissions in the mid-infrared in an ample altitude range. MIPAS spends most of the time observing in its nominal mode (6-68 km), but also looks at high altitudes. In particular, since early in 2005, MIPAS measured in its NLC (38-102 km) and in the upper atmosphere (38-170 km) mode during several periods and routinely measures during 1 day in the middle atmosphere (18-102 km) and 1 day in the upper atmosphere mode every 10 days since mid-2007.

In this paper we show an overview of the products retrieved from middle atmosphere mode with emphasis on the temperature, retrieved under non-LTE from the CO2 15 µm emission. In addition we show other important recent MIPAS results related to SPEs and EEPs (formation mechanisms of N2O and HNO3), to NLCs, and the major features of other mesospheric species.
