U.S. Air Quality

Moderate air quality across eastern half of the U.S.

Areas of light haze across much of the eastern half of the U.S., especially the midAtlantic (Virginia, North Carolina, South Carolina) and midwest (Kansas, Nebraska, Iowa, Missouri, Wisconsin). Ground-based air quality particle concentrations were generally moderate (code yellow). NO2 values from the NASA OMI instrument were elevated particularly in the midAtlantic.
