Canadian Yukon Tree Ring Chronology From 130 to -25 BP

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Montana Mountain site in Yukon Territory, Canada. The dataset provides parameters for reconstructing past climate conditions, covering the period from 130 to -25 calendar years before present. Data is managed by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree ring width parameters.
• Calibrate climate models by comparing the tree ring chronology time-series with other proxy records.
• Study ecological responses, such as the growth of Abies lasiocarpa (ABLA), to historical climate events.

Strengths

• Data spans 155 years, from 130 to -25 calendar years BP, providing a multi-century climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology, ensuring curation standards.

Limitations

• Temporal coverage is limited to a specific 155-year period, which may not capture longer-term climate cycles.
• The dataset's last known update was in 1975, indicating the record is temporally stale and methods may be outdated.
• Geographic scope is restricted to a single site (Montana Mountain, Yukon), limiting regional generalizability.
