A 3-year program of continued research on Arctic haze is planned. The research builds on the accomplishments of the past three years and extends them, with particular emphasis on strengthening the new elemental tracer system, attempting to determine the history of Arctic haze by analyzing the RussianNorwegian ice core from Nordauslandet, and analyzing aircraft samples from the AGASP II aircraft experiment of spring 1986. The tracer system will be improved in at least three ways its statistical aspects will be refined, innovative ways of deriving signatures from hard-to-sample areas will be explored, and the tracer power of several noble metals will be determined. From the Nordauslandet core, as many as 100-200 samples will be analyzed for trace elements with our new technique developed under DOE sponsorship we hope to use the results to write both the modern history of Arctic haze and the history of the various regions contributing to it. An extensive set of aircraft samples from AGASP II will be analyzed for trace elements and compared with the results of other investigators.
