Limb Infrared Monitor of the Stratosphere
Chemistry of the upper atmosphere. Tracked species: H2O, HNO3, NO2 and O3
6-channel radiometer: five narrow-bandwidth with center wavelengths 6.25, 6.75, 9.65, 11.35, 15.25 µm, and one broad channel 13.3-17.2 µm. Spectral resolution about 5 cm-1
Follow-on of LRIR flown on Nimbus-6. Operations terminated after 9 months (limited by the cryogenic cooler)
