White spruce tree-ring-width data in Old Crow Flats, Yukon Territory, 2007-2008

The purpose of this research is to develop climatically sensitive tree ring records from the Old Crow Flats region. It is hoped that these records will extend the temporally short instrumental climate record from Old Crow which currently only covers the period 1951-2004. Such a short record makes it difficult to assess long-term climate trends and variability and accurately define baseline climatic conditions. By using proxy data sources such as tree ring growth records, we can extend the short instrumental climate record further back in time. It is anticipated that this research will produce climatically-sensitive tree ring chronologies extending over the past 2-3 centuries.本研究旨在从旧克劳平原（Old Crow Flats）区域获取气候敏感型树木年轮记录。现有旧克劳地区的器测气候记录仅覆盖1951年至2004年，时间序列极短；此类短促的记录难以用于评估长期气候趋势与变异性，亦无法精准界定气候基准状态。借助树木年轮生长记录这类代用数据源，我们可将短促的器测气候记录的时间跨度回溯至更早时期。本研究预期将生成可覆盖过去2至3个世纪的气候敏感型树木年轮年表。
