Sun-lit snow packs are chemical reactors and reservoirs that strongly influence air quality

For example, ozone is a pollutant and greenhouse gas, and surface concentrations show both dramatic depletion near the sea-ice zone during polar spring and production above inner Antarctica during summer. To date our understanding of the chemical and natural air-snow processes remains incomplete, but is essential to guide legislation to control man-made emissions of ozone pre-cursor gases in the high latitudes.
