Ozone, particulate matter, and temperature extremes

Analyses of 15 years of summer surface observations over the eastern United States and Canada reveal that extreme temperatures and high levels of ozone and particulate matter pollution often co-occur in large-scale, multiday, spatially connected events, and that the largest of these events exhibited the hottest temperatures and highest levels of pollution, findings that may help researchers accurately quantify the effects of such environmental stressors on human health. - Read at PNAS
