Ningunsaw Pass Tree Ring Chronology for Climate Reconstruction

264 to -33 calendar years before present of tree ring width measurements from British Columbia, Canada. The dataset provides parameters for paleoclimate studies, archived by NOAA's World Data Service for Paleoclimatology. Data was contributed by Schweingruber and last updated in 1983.

Use Cases

• Calibrating climate models by correlating tree_ring_width measurements with known temperature/precipitation proxies.
• Reconstructing past temperature anomalies using the standardized tree_ring_index chronology.
• Analyzing long-term climate trends in British Columbia from the 297-year time series coverage.
• Studying forest growth responses to historical climate events recorded in the ring_parameters.

Strengths

• 297-year temporal coverage from 264 to -33 BP provides a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service.

Limitations

• Data recency is limited, with a last update in 1983, potentially missing modern methodological refinements.
• Geographic scope is restricted to a single site (Ningunsaw Pass, British Columbia).
• Specific column names, sample sizes, and measurement parameters are not provided in the input.
