The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) is one of the ten instruments onboard the Envisat satellite launched from Kourou (French Guyana) on the 28th February 2002 and operated by the European Space Agency (ESA). MIPAS is a Fourier transform spectrometer for the measurement of high-resolution gaseous emission spectra at the Earth's limb. It operates in the near- to mid-infrared, where many of the main atmospheric trace gases have important emission features. Its main objectives are to provide simultaneous and global measurements of the middle atmosphere dynamics, radiation budget and chemical composition (O3, H2O, CH4, N2O, HNO3, NO2), and to monitor stratospheric ozone and CFCs.
The data issues by ESA include both Level 1B (emission spectra) and Level 2 (derived quantities) products. They come in a number of versions: a near real time (nrt) version, a consolidated version, result of a first processing by ESA to eliminate bad data and perform a few basic checks, and fully reprocessed spectra. MIPAS is a Fourier transform spectrometer for the measurement of high-resolution gaseous emission spectra at the Earth's limb. It operates in the near- to mid-infrared spectra.
The data routinely archived at the NEODC is received from ESA through different routes (DDS, FTP, tapes). The archive currently includes:
Level 1B data (emission spectra)
NRT data - September 2002 - May 2011
consolidated data - June 2002 - January 2004
reprocessed data - July 2002 - April 2012 - processing versions v4.x (2002-2010) and v5.x (2002-2012)
Level 2 data (derived products)
consolidated data - July 2002 - February 2004
reprocessed data - July 2002 - March 2004
