About TreeFlow TreeFlow is a comprehensive web resource for tree-ring reconstructions of streamflow and climate, providing easy access to reconstruction data as well as information about how the data were developed, and can be used. Click here to learn more about TreeFlow.                                 登录/注册后可看大图                                 登录/注册后可看大图 Data Access by Basin Many tree-ring reconstructions of streamflow, and other hydroclimatic reconstructions, are now available for the western US. Data for the eastern US will be added in the future. Click here to access the reconstructions and other information resources by hydrologic basin. Tree-Ring Background Information A tree-ring reconstruction is a best-estimate of past streamflows, based on the relationship between tree-ring data and observed streamflow over the modern period.

For more information on applications of tree-ring reconstructions to water management, click here. Technical Workshops Our one-day workshops for water managers and stakeholders in Colorado, Utah, Wyoming, Arizona, New Mexico, and Nevada, have comprehensively covered the methods for developing streamflow reconstructions from tree rings. Each workshop has a page with a summary and links to the presentations.

Over the years, much work has been done to assess the long-term variability in its streamflow, using tree rings and other environmental proxies. Click here for a multi-page feature providing a "paleo perspective" on Colorado River streamflow.

古气候重建资料很难得

我@情非得已

英文跟不上啊
