Background Info Tree-Ring Chronologies Streamflow Reconstructions - Data Access Reconstruction Case Study Additional Resources Annual tree growth in California and the West is often closely correlated with variations in precipitation, snowpack, streamflow, and drought indices. Thus, tree rings can be used to reconstruct records of these hydroclimatic variables for the past 500 years or longer. For the California TreeFlow web pages, we've brought together existing hydroclimatic reconstructions for California in a format accessible to water managers and other data users. We also show the locations of existing tree-ring data that could be used to generate new hydroclimatic reconstructions for California. This project is funded by the NOAA/CIRES Western Water Assessment Program, a Regional Integrated Sciences and Assessments program. |
