Since the 1970s, the concern of ozone related to halogen chemistry in pristine polar regions has puzzled scientists. In 1986, first observations of drastic depletions of tropospheric ozone were reported in the Arctic boundary layer. Such depletions are now recognized to be chemically-driven, involving salt aerosols and reactive halogen species from the gas phase.
This book provides a detailed description of polar chemistry and its history. Additionally, key processes such as the formation of frost flowers and brine layer or the precipitation of calcium carbonate are presented. Model results...
