Interferometric monitor for greenhouse gasses for ADEOS

Interferometric monitor for greenhouse gasses (IMG) based on an infrared Fourier transform spectrometer (FTS) is described which is scheduled to be launched onboard the Advanced Earth Observation Satellite (ADEOS) in 1995. The IMG uses the 10 cm aperture Michelson interferometer with a 10 cm traveling scanning mirror and 3 band detector at an operating temperature of 80 K or less which is maintained by the Stirling cycle mechanical cooler. The IMG is characterized by a wide spectral band of 700-300/cm and high spectral resolution of 0.1/cm. It is intended for the global investigation of the greenhouse effects, temperature sounding, air pollutions and gaseous exchange between the troposphere and the lower stratosphere.
