Minimize MIPAS

The Michelson Interferometer for Passive Atmospheric Sounding (MIPAS) MIPAS is a Fourier transform spectrometer for the detection of limb emission spectra in the middle and upper atmosphere. It observes a wide spectral interval throughout the mid infrared with high spectral resolution. Operating in a wavelength range from 4.15 microns to 14.6 microns, MIPAS detects and spectrally resolves a large number of emission features of atmospheric minor constituents playing a major role in atmospheric chemistry. Due to its spectral resolution capabilities and low-noise performance, the detected features can be spectroscopically identified and used as input to suitable algorithms for extracting atmospheric concentration profiles of a number of target species.
