An optimized code to perform the near-real-time retrieval of profiles of pressure, temperature, and volume mixing ratio (VMR) of five key species (O(3), H(2)O, HNO(3), CH(4), and N(2)O) from infrared limb spectra recorded by the Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) experiment on board the European Space Agency (ESA)(More)
The MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) instrument has been operating on-board the ENVISAT satellite since March 2002. In the first two years, it acquired in a nearly continuous manner high resolution (0.025 cm −1 un-apodised) emission spectra of the Earth's atmosphere at limb in the middle infrared 5 region.

The Geostationary Fourier Imaging Spectrometer (GeoFIS) is proposed as part of the European Geostationary Tropospheric Pollution Explorer (GeoTroPE) mission. For this mission, two instruments are considered: one covering the thermal infrared region (GeoFIS) and one covering the ultraviolet–visible and near-infrared regions (GeoSCIA). The geostationary orbit(More)
The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) is a limb-scanning spectrometer that has operated onboard the Environmental Satellite since the end of March 2002. Common features of limb-scanning experiments are both high vertical resolution and poor horizontal resolution. We exploit the two-dimensional geo-fit retrieval approach(More)
Hydrogen bromide (HBr) is the principal bromine sink species for the ozone loss chemistry induced by bromine-containing gases in the stratosphere. We report a 1994 balloon based measurement of the daytime stratospherie HBr profile between 20 and 36.5 km altitude. The average concentration result of 1.31 + 0.39 parts per trillion in volume (pptv) and an(More)
MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) is a Fourier transform spectrometer operating on board the ENVISAT satellite and is acquiring high spectral resolution middle infrared emission limb sounding spectra of the Earth atmosphere from space. The instrument measures an interferogram that is transformed and calibrated in the Level 1(More)
MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) is operating on board of the ENVISAT satellite and is acquiring for the first time high spectral resolution middle infrared emission limb sounding spectra of the Earth atmosphere from space. The measurement capabilities of this instrument make it possible to determine every 75 sec the(More)

Email: B.Carli@ifac.cnr.it (b) ISAC-CNR, via Gobetti 101 – 40129 Bologna (Italy) ABSTRACT Atmospheric vertical profiles of temperature, pressure and concentrations of O 3 , H 2 O, CH 4 , HNO 3 , N 2 O and NO 2 , in the altitude range from 12 to 68 km are routinely retrieved from the measurements of(More)
Far infrared spectral features of HBr have been observed in the stratospheric emission spectrum using a balloon borne high resolution Fourier transform spectrometer equipped with a high sensitivity detector specially designed for this purpose. The value of 1.6 + 0.6 parts per trillion in volume for the HBr mixing ratio has been retrieved, from the(More)
