How Severe Drought Influences Ozone Levels
From 2011 to 2015, California experienced its worst drought on record, with a parching combination of high temperatures and low precipitation. 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. They report their results in ACS’ journal Environmental Science & Technology. Although ozone in the stratosphere protects the earth from ultraviolet radiation, at ground level the molecule is a …
