This paper gives an overview of the MIPAS Level 1B (L1B) processor whose main objective is to calibrate atmospheric measurements radiometrically, spectrally and geo-located. It presents also the results of instrument characterization done on ground and during the first years in-flight. An accurate calibration is mandatory for high quality atmospheric(More)
Acacia cyclops is an invasive species within Mediterranean ecosystems, characteristically low in soil nutrients. Thus associations with nitrogen-fixing bacteria (NFB) and arbuscular mycorrhiza (AM) may provide an advantage to these legumes. This study investigated the role of AM and NFB in the growth and nutritional physiology of A. cyclops. Seedlings were(More)
This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract The winter 2009/2010 was characterized by a strong Arctic vortex with extremely cold midwinter temperatures in the lower stratosphere associated with an intense activation of(More)
Embedded in the Envisat validation programme of the chemistry instruments GOMOS, MIPAS, and SCIAMACHY a balloon flight was carried out with MIPAS-B, the balloon borne version of MIPAS, on September 24, 2002 from Aire sur l'Adour, France, adjusted to the nighttime overpass of orbit 2975. This paper outlines the instrumental characteristics of MIPAS-B, the(More)
Organic compounds play a central role in troposphere chemistry and increasingly are a viable target for remote sensing observations. In this paper, infra-red spectral features of three organic compounds are investigated in thermal emission spectra recorded by a balloon-borne instrument, MIPAS-B2, operating at high spectral resolution. It is 5 demonstrated,(More)
The Improved Limb Atmospheric Spectrometer (ILAS)-II sensor aboard the Japanese ADEOS-II satellite was launched into its sun-synchronous orbit on 14 Decem-ber 2002 and performed solar occultation measurements of trace species, aerosols, temperature, and pressure in the polar stratosphere until 25 October 2003. Vertical trace gas profiles obtained with the(More)
