    Planes like this will fly over the D.C. region.

    If you see low-flying jets over Maryland today, it could be NASA scientists. They're in the middle of an air pollution study in our region.

    The air and ground research started at the beginning of July. Observation sites on the ground are monitoring surface-level pollution.  NASA says these low-altitude measurements will help researchers understand the difference between surface-level smog and the pollution detected at higher altitudes by satellites.

    The plane is measuring ozone levels and particulate matter.

    Today, a research plane will fly over the Beltway and I-95 up to Baltimore from 11 a.m. until 7 p.m.

    Similar flights will continue throughout the month.
