This award is to support research that will develop a network of tree-ring records covering the past 3,000 years from the western United States. These data will be used to understand the temporal and geographic variability of Holocene climate in western North America.Field work will be undertaken to obtain tree-ring records of appropriate length from regions currently lacking high resolution time series. Existing tree-ring archives will be carefully analyzed to select the best 3000+ year records of climate. These records will be integrated into a network with sufficient geographic coverage to be useful for ocean-atmosphere modeling studies. The resulting network of records will be used to produce a variety of climate reconstructions ranging from long regional reconstructions to synoptic reconstructions of the western United States. The broader impacts of this proposed research center on the development of a network of high resolution climate records from the western United States that can be used to fully explore the range and frequency of climate change. This tool is presently not available and will have a wide range of applications for paleoclimatology, oceanography and other subdisciplines of climate change.

该奖项是为了支持将开发一个覆盖美国西部过去3,000年的树木年轮记录网络的研究。 这些数据将用于了解北美西部全新世气候的时间和地理变异性，将进行实地工作，从目前缺乏高分辨率时间序列的地区获得适当长度的树木年轮记录。 现有的树木年轮档案将被仔细分析，以选择最好的3000+年的气候记录。 这些记录将被纳入一个具有足够地理覆盖范围的网络，以用于海洋-大气模拟研究。 由此产生的记录网络将用于产生各种气候重建，从长期的区域重建到美国西部的天气重建。这个拟议的研究中心对美国西部高分辨率气候记录网络的发展产生了更广泛的影响，该网络可用于充分探索气候变化的范围和频率。 这一工具目前尚不可用，将在古气候学、海洋学和气候变化的其他分支学科中有广泛的应用。
