Severe drought influences ozone pollution

Green Car Congress

Drought conditions can have complicated effects on ozone air quality, so to better understand the process, researchers have analyzed data from two ozone-polluted cities before, during and after the California drought. Although ozone in the stratosphere protects the earth from ultraviolet radiation, at ground level the molecule is a harmful air pollutant to humans, animals and plants. However, plants also decrease air ozone levels by taking the gas up through pores in their leaves.
