Stratospheric and Mesospheric Sounder
Stratospheric and mesospheric profiles of temperature, CH4, CO, CO2, H2O, N2O and NO
Pressure-modulated correlation spectrometer with 9 cells for: temperature and CO2 (4.3 and 15 μm), CO (4.7 μm), CH4 and N2O (7.7 μm), NO (5.3 μm) and H2O (2.7 μm and 25-100 μm). Spectral resolution about 5 cm-1
Follow-on of SCR flown on Nimbus-4/5 and PMR flown on Nimbus-6. Now the scanning is limb instead of nadir
Limb scanning, both vertically (5-km steps) and in azimuth (100 km)
Vertical: 10 km, horizontal: 300 km along-view
Coverage / Cycle
Global in about 3 days for cells of 300 km side
