NASA satellite data of regional haze allow EPA scientists to expand their focus from local to regional air quality monitoring and forecasting.

By measuring the total amount of energy that the sun delivers to the Earth with ACRIMSAT, scientists will be able to build better scientific models of the Earth’s climate system, providing a vital piece of the global climate change puzzle.

The Vulcan Project maps when and where Americans burn fossil fuels.

Aqua carries six state-of-the-art instruments to observe the Earth's oceans, atmosphere, land, ice and snow covers, and vegetation, providing high measurement accuracy, spatial detail, and temporal frequency. This comprehensive approach enables scientists to study interactions among the many elements of the Earth system.

The Destiny Laboratory aboard the International Space Station includes the best optical quality window ever flown on a human-occupied spacecraft. Through this window, astronauts are photographing the Earth’s surface as part of an early project, called Crew Earth Observations

On July 15, 2004 at 3:02 a.m., NASA launched the Aura satellite, the third flagship in a series of Earth-observing satellites designed to view Earth as a whole system, observe the net results of complex interactions within the climate system, and understand how the planet is changing in response to natural and human influences.
