Annie Lake Tree Ring Chronology for Paleoclimate Reconstruction

Tree ring width data from the Annie Lake site in Yukon Territory, Canada, provides a proxy record for past environmental conditions. The chronology covers 225 years, from 200 to 25 calendar years before present. This archived study is maintained by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Calibrating climate models using the 225-year tree-ring width time series as a proxy for past temperature or precipitation.
• Analyzing growth anomaly patterns within the chronology to identify extreme climatic events like droughts or cold periods.
• Correlating the Annie Lake ring-width series with other regional proxy records to reconstruct broader climate patterns.

Strengths

• Data spans a continuous 225-year period, providing a multi-century climate proxy.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to 225 years, which is relatively short for some paleoclimate studies.
• Data is geographically specific to a single site (Annie Lake, Yukon), limiting regional generalization.
• The dataset was last updated in 1975, indicating it is a static archive with no recent revisions.
