If you walked outside today (Friday, Aug. 17), you may have noticed the haze. It was a code orange air quality, which means air pollution levels are predicted unhealthy for elderly and sensitive groups. The air quality index (AQI) was near 100, which indicates moderate levels of air pollution. Take a look at what it looked like over Maryland and Virigina from space via the NASA Terra satellite (image below).
To put this into perspective - take a look at how clear it was just one day earlier (image below)! A lot can change in 24 hours! The air quality on Thursday was green with an AQI between 0 and 50. Green air quality indicates satisfactory levels of air pollution.
