The processes that create ozone pollution in the summer can also trigger the formation of wintertime air pollution, according to a new study from researchers at the University of Colorado Boulder and NOAA, in partnership with the University of Utah. A key control strategy is to reduce emissions of the limiting reagent.

CSIRO scientists have developed a new way to account for ozone in computer simulations of the climate. This latest modeling shows that the oceans take much less ozone out of the atmosphere than previously thought. Ozone (O 3 ) is formed by reactions of chemicals such as nitrogen oxides and volatile organic compounds—i.e.,
