Sunrise Lake Tree Ring Chronology From Washington State

Tree ring width measurements from the Sunrise Lake site in Washington, USA, provide a 495-year climate proxy record. The dataset, archived by NOAA's World Data Service for Paleoclimatology, covers the period from 463 to -32 calendar years before present. This chronology was published in 1982 as part of the International Tree-Ring Data Bank.

Use Cases

• Calibrating tree ring width variations against modern climate data to reconstruct past temperature or precipitation for the Washington region.
• Cross-dating the chronology (ITRDB WA064) with other regional tree ring series to validate climate signals and extend temporal coverage.
• Analyzing the growth trend over the 495-year span to infer periods of climatic stress or favorable conditions for tree growth.

Strengths

• Covers a long temporal span of 495 calendar years.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA NCEI.

Limitations

• The dataset's last update was in 1982, making it temporally stale compared to modern dendrochronological methods.
• Specific sample depth, measurement statistics, and site metadata are unknown without accessing the full study files.
