Definition
- The Interferometric Monitor for Greenhouse Gases (IMG) instrument is provided by the Ministry of International Trade and Industry (MITI) of Japan for the ADvanced Earth Observation Satellite (ADEOS). The IMG is designed to monitor the horizontal distribution of greenhouse effect gases (carbon dioxide, methane, nitrous oxide, etc.) and the vertical distribution of temperature and water vapor. The IMG uses an interferometric spectrometer which scans the spectrum from the middle infrared to thermal infrared (0.3 to 15 microns). A mechanical cryogenic coolant system is used to regulate the temperature of the quantum detectors. An image motion compensation mirror is used to compensate for the satellite orbital motion. Measurements are made in 20 km swaths at 8 km resolution.
