NO2 in the Troposphere
View collection of movies created from Aura's OMI instrument of NO2 in the troposphere.
OMI captured the SO2 cloud in 2 consecutive orbits of the eruption in the Aleutians.
Air Quality during the Olympics
Restrictions were put on traffic and power plants to improve air quality in Beijing during the Olympics. OMI makes daily measurements of the total column of SO2
Sulfur dioxide measurements from the Ozone Monitoring Instrument (OMI) on Aura permitted tracking of the eruption cloud in near real-time.
Springtime OMI Measurements of BrO
Despite its low atmospheric abundance, bromine monoxide (BrO) plays an important role in the chemistry of the atmosphere because it is a catalyst of the ozone destruction.
Chaiten volcano Eruption
The Chaiten volcano eruption in southern Chile caught local authorities by surprise as experts say it has been dormant for at least 450 years.
Llaima Volcano Eruption
The Llaima Volcano is one of Chile's most active volcanoes and has frequent but moderate eruptions. An eruption on January 1, 2008 forced the evacuation of hundreds of people from nearby villages.

Satellite Data Reveal Impact of Olympic Pollution Controls
12.16.2008 - Chinese government regulators had clearer skies and easier breathing in mind in the summer of 2008 when they temporarily shuttered some factories and banished many cars in a pre-Olympic sprint to clean up Beijing's air.
2008 Ozone Hole Maximum Announced
10.31.2008 - The Antarctic ozone hole reached its annual maximum on Sept. 12, 2008, stretching over 27 million square kilometers, or 10.5 million square miles. The area of the ozone hole is calculated as an average of the daily areas for Sept. 21-30 from observations from the Ozone Monitoring Instrument (OMI) on NASA's Aura satellite.
Sulfur Dioxide and Vog from Kilauea
04.26.2008 - In late April 2008, Kilauea Volcano Volcano on Hawaii's big island continued its pattern of increased activity, including elevated seismic tremors and emissions from the volcano's Halema'uma'u vent.
Air Quality Forecasts See Future in Space
12.13.2007 - Weather broadcasts have long been a staple for people planning their day. Now with the help of NASA satellites, researchers are working to broaden daily forecasts to include predictions of air quality, a feat that is becoming reality in some parts of the world.
