Tree ring width measurements from a site on Prince of Wales Island, Alaska, used for paleoclimate reconstruction. The chronology covers a 387-year period from 351 to -36 calendar years before present. The data was archived by the NOAA National Centers for Environmental Information and last updated in 1986.
Use Cases
- Reconstruct past temperature or precipitation anomalies from annual tree ring width measurements.
- Calibrate tree ring growth chronologies against other regional proxy records for cross-validation.
- Analyze the frequency and magnitude of climatic events captured in the ring width time series.
Strengths
- Data covers a 387-year time period (351 to -36 BP).
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -36 BP (1986 CE), providing no recent data.
- Geographic scope is limited to a single site on Prince of Wales Island.
