Airborne expedition tackles global air quality problem

California, Apr 22 (IBNS): NASA has marshalled some top-notch scientific know-how to take on a global public health problem: air pollution. Over the next six weeks, scientists will fan out across and above South Korea seeking to capture the intricate and elusive ebb and flow of changing air quality conditions. The data they collect will be used to help find new solutions to this health threat, not just on the Korean Peninsula but all around the world.
