| Popis: | The microwave limb sounder is one of four instruments on the NASA Earth Observing System Aura spacecraft, launched 15 July 2004 into a near-polar sun-synchronous ~705 km altitude orbit, which gives global coverage, day and night, with ~13 orbits per day. The instrument passively views thermal emission from the limb of the Earth’s atmosphere in ~1,000 microwave channels, viewing forward in the satellite flight direction. The antenna scans in the orbit plane from the surface to ~100 km altitude at the limb every ~25 s, a total of ~3,500 scans per day with 148 integration periods per scan, giving >500 million measurements per day. We solve for ~20 quantities that characterize the upper atmosphere at each of ~70 levels on each scan, or ~5 million results per day. |
