Cloudy skies persist over East; Moderate air quality observed in Northeast

The trend of cloudy skies over the Eastern US continues as can be seen in today's MODIS Aqua true color image (left). In terms of air quality however, compared to the rather clean conditions that we've been observing throughout most of the US in the last couple of days, the Northeast and Midwest regions experienced increased PM2.5 concentrations today, ranging between good and moderate conditions (right). Southern California and Arizona also experienced moderate levels of PM2.5.

No significant areas of fire and/or smoke were reported by the HMS team.
