Hart's Pass Tree Ring Chronology for Paleoclimate Reconstruction

Tree ring width measurements from Hart's Pass, Washington, USA, form a chronology spanning 181 years from 141 to -40 calendar years before present. The dataset is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. This paleoclimatology study was published in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width chronology as a climate proxy.
• Calibrate the chronology against known climate events using the provided calendar years before present (BP) time axis.
• Compare growth patterns from this Washington site with other tree ring chronologies to study regional climate teleconnections.
• Validate radiocarbon dating or other dating methods using the precisely dated tree ring sequence.

Strengths

• Chronology covers a 181-year period, providing a multi-decadal climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -40 BP (approximately 1990 CE), lacking recent decades.
• Sample size, replication, and species information are unknown from the provided metadata.
• Geographic coverage is limited to a single site (Hart's Pass, Washington).
