Aura delivering daily data on pollution.(Brief Article)

GEO World, February, 2005

NASA's Aura spacecraft is providing daily, direct global measurements of low-level ozone and other pollutants affecting air quality. Aura should help scientists monitor global pollution production and transport with "unprecedented" spatial resolution.

"Data from NASA missions like Aura are a valuable national asset," said Phil DeCola, Aura Program scientist at NASA headquarters. "Clean air is a vital need, and air quality is not merely a local issue.

"Pollutants do not respect state or national boundaries," he added. "They can degrade air quality far from their sources. Aura's view from space enables us to understand the long-range transport of pollutants."

Scientists hope to use Aura to examine processes for local and global air quality...
