Assessing Air Quality from Space
NO2-Population508.pdf

Learn about the direct connection between population density in the United States and air pollution in this striking comparison between 3 maps: the 2010 census, U.S. city lights at night, and nitrogen dioxide concentration.

Observing Air Quality from Space
2007NO2flip508.pdf

Compare three major air pollutants, their sources, and how they were distributed across the globe in 2005: nitrogen dioxide, tropospheric ozone, and particulate matter.

Sea Ice
2007Sea_Ice508.pdf

This card introduces the subject of the seasonal cycles of sea ice in the Arctic and Antarctic polar climate systems.

Earth by Day, Earth by Night
2006DayNight508.pdf

See where urban populations of the developed world are concentrated around the globe. Compare Earth’s daytime map of the continents with a compelling global view of Earth’s city lights at night.

NASA's Science Mission Directorate
2006SMD_Postcard508.pdf

NASA determines Earth’s place in the universe.

Air Pollution: Europe from Space, 2005-2010 (2012)
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.

Earth Observatory (2011)

Find out what NASA’s Earth Observatory has to offer.

NASA AQAST: Serving the Needs of U.S. Air Quality Management (2011)
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.

NASA Hurricane and Severe Storm Sentinel (2012)
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.

NASA's Hyperwall: Revealing the Big Picture (2011)
2011508_Compliant_HYPERWALL_PromoCard_EARTH.pdf

We invite you to explore science at NASA. From the universe, to your backyard, we’ve got something to show you! Wondering what The Big Picture on the front of this card is all about? Find out on the other side. For starters, we’ve chosen a few examples of stories you may have seen on NASA’s Hyperwall. But that’s not all, you’ll also find links that allow you to discover extraordinary examples of our changing planet, and watch fascinating visualizations from NASA’s Scientific Visualization Studio.
