NASA scientists and aircraft took to the skies above Fresno and Bakersfield today. It's part of a project that one day hopes to predict and air quality from space.
Two aircraft, including a converted Navy P3-B flew repeated loops over various valley cities today, one of them as low as 1,000 feet, to gather air samples. It's part of a program NASA calls DISCOVER-AQ which aims to better understand pollution spikes and how pollutants react with sunlight throughout the day.
