The Michelson Interferometer for
Passive Atmospheric Sounding (MIPAS) is an high resolution Fourier
Transform Spectrometer developed by ESA for the detection of limb emission
spectra in the upper atmosphere. It is a powerful tool to measure vertical
profiles of trace species on a global scale. MIPAS has been successfully
launched on board Envisat-1, on 1st March 2002.
While operational data processing by ESA covers only analysis of pressure,
temperature, and the mixing ratios of the species O3, H2O, HNO3, CH4, N2O and
NO2, MIPAS infrared spectral limb emission measurements contain information
on a bulk of further species relevant to environmental problems.
The goal of AMIL2DA is to generate data analysis tools for these
supplemental species along with thorough validation of these algorithms.
The scientific groups participating to the AMIL2DA project use their own
retrieval codes to analyse the spectra of these
supplemental species and also of the operational species with algorithms of
In order to guarantee consistent and reliable data sets, which will be used
by the scientific community, an intercomparison
and characterization of the different algorithms and data sets are
performed. AMIL2DA aims at a reasonable standardization of data products
without sacrificing the diversity of data analysis strategies used by the
different European groups. These activities will approve the acceptance of
MIPAS data by the scientific community and will help to better exploit
MIPAS data for purposes of atmospheric science.
