Hart's Pass Tree Ring Chronology For Pacific Silver Fir

312 years of tree-ring width data from 271 to -41 calendar years before present, providing a proxy record for past climate conditions. This paleoclimatology dataset was created by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was last updated in the archive on 1991-01-01.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree-ring width series.
• Calibrate climate models using the 312-year proxy record from the Pacific Silver Fir (Abies lasiocarpa).
• Study long-term ecological growth patterns and responses to environmental stressors using the ring-width chronology.
• Perform cross-dating with other regional tree-ring chronologies to validate and extend climate reconstructions.

Strengths

• Covers a 312-year time period from 271 to -41 calendar years BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a specific proxy record for a defined geographic location in Washington, USA.

Limitations

• Data archive was last updated in 1991, indicating potential staleness and lack of recent methodological revisions.
• The raw sample size, replication, and measurement details are unknown from the provided metadata.
• Geographic coverage is limited to a single site (Hart's Pass), which may not represent broader regional patterns.
