NOAA/WDS Paleoclimatology archives a tree-ring width chronology from the Hager Basin Reservoir site in California. The dataset provides a paleoclimate record covering the period from 450 to -30 calendar years before present. This study is maintained by the NOAA National Centers for Environmental Information.
Use Cases
- Calibrating climate models by comparing tree-ring width variations against known historical climate events.
- Reconstructing past temperature or precipitation anomalies in California using the tree-ring width proxy.
- Analyzing the frequency of extreme climatic events, such as droughts, within the 480-year chronology.
- Establishing a dated timeline for archaeological or geological events in the region using the tree-ring series.
Strengths
- Time series covers approximately 480 calendar years (450 to -30 BP).
- Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.
Limitations
- The dataset's last known update was in 1980, indicating potential staleness in metadata or access methods.
- Sample size and replication statistics for the tree-ring measurements are unknown.
- Geographic coverage is limited to a single site (Hager Basin Reservoir) in California.
