gen oxides and ozone near the ground.
An instrument called the MOPITT, which stands for Measurements of Pollution in the Troposphere (the Earth’s lowest layer of atmosphere), can pinpoint such air pollution with a resolution of 14 miles at its lowest orbit. It can measure the concentrations of carbon monoxide in three-mile layers down a vertical column of atmosphere and help trace pollution back to its source. Field studies may then be used to isolate the specific sources. Increased regulation or possible legal action might then be initiated.
