NOAA/WDS Paleoclimatology archives a Douglas fir (PSME) tree-ring chronology from Mount Pilchuck, Washington. The dataset provides proxy climate data covering a 348-year period from 322 to -26 calendar years before present. It was published by the NOAA National Centers for Environmental Information in 1976.
Use Cases
- Reconstruct annual temperature or precipitation anomalies from the tree-ring width chronology.
- Calibrate climate models using the 348-year proxy record for the Pacific Northwest region.
- Analyze growth patterns in Douglas fir (PSME) linked to documented historical climate events.
- Compare this Mount Pilchuck site chronology with other ITRDB WA034 series for regional climate signal analysis.
Strengths
- Covers a continuous 348-year time period for long-term trend analysis.
- Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection from NOAA/NCEI.
Limitations
- Temporal coverage ends 26 years before present (1950 baseline), lacking recent decades.
- Data is from a single tree species (PSME) at one geographic site, limiting spatial representativeness.
- Last metadata update was in 1976, indicating potential staleness in documentation.
