St. Peter's Creek Tree Ring Chronology from Washington State

Tree ring width measurements from a Pseudotsuga menziesii (Douglas-fir) site at St. Peter's Creek in Washington, United States. The chronology covers a 150-year period from 125 to -25 calendar years before present. Data is archived by NOAA's World Data Service for Paleoclimatology.

Use Cases

• Reconstruct annual temperature or precipitation anomalies for the 150-year period using tree ring width as a proxy.
• Calibrate the chronology against other regional tree ring series to validate climate signals.
• Analyze growth response to specific historical climate events within the recorded time span.

Strengths

• Data covers a 150-year time period (125 to -25 BP)
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology

Limitations

• Sample size is unknown, potentially from a single tree or small site
• Temporal coverage is relatively short for many paleoclimate studies
• Data last updated in 1975, indicating potential staleness in metadata or availability
