Code Red Air over the Mid-Atlantic States
This page contains archived content and is no longer being updated. At the time of publication, it represented the best available science. However, more recent observations and studies may have rendered some content obsolete.
A whitish haze drifts out over the Atlantic Ocean from the mid-Atlantic
United States. This Sea-viewing Wide Field-of-view Sensor (SeaWiFS) image acquired
on June 28, 2001, shows a shroud of aerosol draped over much of the
eastern U.S., including parts of Virginia, Maryland, and Pennsylvania.
The aerosol could be a mixture of pollution, smoke, and cirrus clouds,
and indeed many eastern cities, including Washington, DC, and
Baltimore, MD, were under poor air quality advisories June 26-29.
