Michael J. Schwartz,Alyn Lambert,Gloria L. Manney,Gloria L. Manney,William G. Read,Nathaniel J. Livesey,Lucien Froidevaux,Chi O. Ao,Peter F. Bernath,Peter F. Bernath,C. D. Boone,R. E. Cofield,William H. Daffer,Brian J. Drouin,Eric J. Fetzer,R. A. Fuller,Robert Jarnot,Jonathan H. Jiang,Yan Jiang,Brian Knosp,Kirstin Krüger,Jui-Lin Li,Martin G. Mlynczak,Steven Pawson,James M. Russell,Michelle L. Santee,W. V. Snyder,P. C. Stek,R. P. Thurstans,Adrian M. Tompkins,P. A. Wagner,Kaley A. Walker,Kaley A. Walker,Joe W. Waters,Dien Wu +34 more
TL;DR: In this article, the authors describe the retrievals algorithm used to determine temperature and height from radiance measurements by the Microwave Limb Sounder on EOS Aura, which is a "limbscanning" instrument, meaning that it views the atmosphere along paths that do not intersect the surface.
Journal ArticleDOI
Aura Microwave Limb Sounder Observations of Dynamics and Transport During the Record-Breaking 2009 Arctic Stratospheric Major Warming
Gloria L. Manney,Gloria L. Manney,Michael J. Schwartz,Kirstin Krüger,Michelle L. Santee,Steven Pawson,Jae N. Lee,William H. Daffer,R. A. Fuller,Nathaniel J. Livesey +9 more
TL;DR: A major stratospheric sudden warming (SSW) in January 2009 was the strongest and most prolonged on record as discussed by the authors, and the 2009 SSW had a more profound impact on the lower stratosphere than any previously observed SSW, with no significant recovery of the vortex in that region.
Journal ArticleDOI
Validation of Aura Microwave Limb Sounder stratospheric ozone measurements
Lucien Froidevaux,Yan Jiang,Alyn Lambert,Nathaniel J. Livesey,William G. Read,Joe W. Waters,Edward V. Browell,J. W. Hair,Melody A. Avery,T. J. McGee,Laurence Twigg,Grant Sumnicht,Kenneth W.

Wagner +38 more
TL;DR: In this paper, the Earth Observing System (EOS) Microwave Limb Sounder (MLS) aboard the Aura satellite has provided essentially daily global measurements of ozone (O3) profiles from the upper troposphere to the upper mesosphere since August of 2004.
Journal ArticleDOI

TL;DR: In this article, the performance of the version 2.2.2 water vapor and nitrous oxide measurements from the Microwave Limb Sounder (MLS) on the Earth Observing System (EOS) Aura satellite is assessed.
