OMI versus AQS data for Houston Texas. The filled circles represent trends for EPA AQS surface monitors.
Monthly OMI Nitrogen Dioxide data (top panel) and de-seasonalized data (bottom panel) for Houston Texas
Satellite data show that Houston has seen a 24 percent decrease in nitrogen dioxide between the 2005-2007 and 2009-2011 periods. In Houston, industry largely influences nitrogen dioxide pollution, centered in this image northeast of Beltway 8. Still, air quality in this region is also on the mend. In addition to satellites, NASA also used scientific instruments on aircraft in 2013 to learn about Houston's air quality as part of the DISCOVER-AQ mission.
