摘要: [1] Global satellite observations of temperature and geopotential height (GPH) from the Microwave Limb Sounder (MLS) on EOS Aura spacecraft are discussed. The precision, resolution, accuracy data produced by MLS version 2.2 processing algorithms quantified, recommendations for screening made. Temperature precision is 1 K or better 316 hPa to 3.16 hPa, degrading ∼3 at 0.001 hPa. vertical resolution 3 km 31.6 6 ∼13 Comparisons with analyses (Goddard Earth Observing System 5.0.1 (GEOS-5), European Centre Medium-range Weather Forecasts (ECMWF), Met Office (MetO)) other (CHAllenging Minisatellite Payload (CHAMP), Atmospheric Infrared Sounder/Advanced Unit (AIRS/AMSU), Sounding Atmosphere using Broadband Radiometry (SABER), Halogen Occultation Experiment (HALOE), Chemistry (ACE), radiosondes) indicate that has persistent, pressure-dependent biases which between −2.5 +1 10 100-hPa v2.2 GPH surface a bias ∼150 m relative GEOS-5 values. These compared modeled systematic uncertainties. correlative measurements generally increase owing an overall cold in upper stratosphere mesosphere.
