White Pass Tree Ring Chronology for Climate Reconstruction

195 annual tree-ring measurements from 159 to -36 calendar years before present provide a paleoclimate record for Washington, USA. The dataset is part of the NOAA NCEI World Data Service for Paleoclimatology and is classified as a Tree Ring study. Data was archived by NOAA and last updated in 1986.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual ring-width time-series.
• Calibrate climate models using the 195-year proxy record from the White Pass location.
• Perform cross-dating with other regional tree-ring chronologies using the shared calendar year BP timeline.
• Study the response of PSME (Douglas-fir) growth to historical climate events within the recorded period.

Strengths

• Covers a continuous 195-year period from 159 to -36 BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends 36 years before present (1950 CE), limiting analysis of recent climate trends.
• Data is from a single geographic location (White Pass, Washington), reducing regional representativeness.
• Last update was in 1986, indicating the record has not been recently extended or revised.
