The suite of TES observations allows quantification of the impact of seasonal biomass burning pollution on the already poor air quality of the world's megacities.
TES measurements of key chemical species allow us to examine not only air quality within the megacity, but also the regional and larger-scale implications of Mexico City pollution as it is transported out of the urban area.
Put a Lid on It
06.27.14 - Aura's Ozone Monitoring Instrument (OMI) images show that the effects of federal and state efforts have left the air far cleaner than it was a decade prior.

NASA Puzzles Out Ozone's Ups and Downs
04.25.14 - New NASA research on natural ozone cycles suggests ozone levels in the lowest part of Earth's atmosphere probably won't be affected much by projected future strengthening of the circulating winds that transport ozone between Earth's two lowest atmospheric layers.
Aura Satellite Sees Increase of India's Sulfur Dioxide Emissions
12.19.13 - Power plant emissions of sulfur dioxide -- an atmospheric pollutant with both health and climate impacts -- have increased across India in recent years, according to a new analysis of data from a NASA satellite.
Dr. Bryan N. Duncan is a deputy project scientist for the Aura Mission at NASA Goddard. In this talk he tells the story of air quality in three cities- Beijing, Los Angeles, and Atlanta.
Dr. Paul Newman is the chief scientist for atmospheric sciences at NASA Goddard. In this talk he discusses how chlorofluorocarbons were destroying the ozone layer, what policy-makers did about it, and what challenges the ozone layer faces today.
