NASA Planes Fly Over Bay Area to Measure Air Pollution Level

An anonymous reader writes: NASA is trying to measure the air pollution by flying a plane at various altitudes. The tests are a part of a larger effort led by the DISCOVER-AQ campaign — a multi-year program launched across the United States in 2011 by NASA's Langley Research Center in Hampton, Virginia. DISCOVER-AQ stands for Deriving Information on Surface conditions from Column and Vertically Resolved Observations Relevant to Air Quality. NASA's Langley Research Center in Hampton, Va., is the lead center for the mission.
