Arctic haze, a winter-spring air pollution phenomenon in the Arctic, has recently become the focus of accelerating research interest. In the spring of 1983 alone, at least seven atmospheric research aircraft from four nations were involved in studies related to Arctic haze. Extensive ground measurements of haze parameters were conducted by five countries with interests in the Arctic.
These and earlier programs have produced new and exciting information covering a diverse range of topics. To assist in the overall study, interpretation, and dissemination of these data in a timely manner, a special issue/section of Geophysical Research Letters will be dedicated to the subject of Arctic haze and related meteorological/atmospheric studies. Publication is planned for the spring of 1984.
