TL;DR: It is demonstrated that chemical ozone destruction over the Arctic in early 2011 was—for the first time in the observational record—comparable to that in the Antarctic ozone hole.
Journal ArticleDOI

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
Asian monsoon transport of pollution to the stratosphere.

TL;DR: The monsoon circulation provides an effective pathway for pollution from Asia, India, and Indonesia to enter the global stratosphere, using satellite observations of hydrogen cyanide (HCN), a tropospheric pollutant produced in biomass burning.
Journal ArticleDOI

TL;DR: In this paper, a large number of isotopic data sets (four satellite, sixteen ground-based remote-sensing, five surface in situ and three aircraft data sets) are analyzed to determine how H2O and HDO measurements in water vapor can be used to detect and diagnose biases in the representation of processes controlling tropospheric humidity in atmospheric general circulation models (GCMs).

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.
