NASA's Science Mission Directorate
PDF icon 2006SMD_Postcard508.pdf

NASA determines Earth’s place in the universe.

This publication appears in:

Air Pollution: Europe from Space, 2005-2010 (2012)
PDF icon NO2_EuropeLenticular_508.pdf

A close-up look at air quality over Europe, 2005-2010, as detected from satellite. See how population and industrialization affects nitrogen dioxide (NO2) levels and how concentrations of this pollutant have changed over time.

NASA AQAST: Serving the Needs of U.S. Air Quality Management (2011)
PDF icon 2011508_Compliant_NO2_2005-11_US.pdf

In 2011, NASA’s Applied Sciences Program created the Air Quality Applied Sciences Team, or AQAST, to serve the needs of U.S. air quality management through the use of Earth science satellite data, suborbital data, and models. Satellites are a powerful resource for monitoring changes in air quality. This card shows annual mean satellite observations of tropospheric nitrogen dioxide decrease between 2005 and 2010 as a result of federal and state regulations on emissions.

This publication appears in:

NASA Hurricane and Severe Storm Sentinel (2012)
PDF icon 2012NASA_Hurricane_and_Severe_Storm_Sentinel_HS3_508 Compliant.pdf

Learn how NASA plans to use Unmanned Aircraft Systems (UAS) to study hurricanes and severe storms in the Atlantic Basin.
