Improved Stratospheric and Mesospheric Sounder
Atmospheric chemistry. Tracked species: CH4, CO, H2O, HNO3, N2O, N2O5, NO, O3 and aerosols
Pressure-modulated correlation spectrometer, eight cells in the spectral range 4.6-16.6 µm. Spectral resolution about 5 cm-1
Follow-on of SAMS flown on Nimbus-7. Early failure in July 1992
Limb sounding. Sampling at 200 km intervals
Vertical: 2.4 km; horizontal: 300 km along-view
