Validation of Aura Microwave Limb Sounder stratospheric ozone measurements

摘要: [1] The Earth Observing System (EOS) Microwave Limb Sounder (MLS) aboard the Aura satellite has provided essentially daily global measurements of ozone (O3) profiles from upper troposphere to mesosphere since August 2004. This paper focuses on validation MLS stratospheric standard product and its uncertainties, as obtained 240 GHz radiometer measurements, with a few results concerning mesospheric ozone. We compare average differences scatter matched version 2.2 coincident other instruments, well aircraft lidar taken during Validation Experiment (AVE) campaigns. Ozone comparisons are also made between balloon-borne remote in situ sensors. provide detailed characterization random systematic uncertainties for typically find better agreement using than 1.5 data. uncertainty estimates stratosphere often order 5%, values closer 10% (and occasionally 20%) at lowest altitudes, where small positive biases can be found. There is very good latitudinal distributions data along track.
