NASA Airborne Mission Chases Air Pollution Through the Seasons

Earth is a planet that breathes with the seasons. In winter months atmospheric gases and air pollution accumulate, waiting dormant until spring and summer bring sunshine and plant-life, sparking transformations that change the make-up of gases in the atmosphere. A NASA airborne mission will take a world-wide survey of these seasonal transformations by flying from the heart of winter in the Northern Hemisphere, down into the sunny summer in the Southern Hemisphere and back again.
