Hart's Pass Tree Ring Chronology For Paleoclimate Reconstruction

322 calendar years of tree-ring data from Washington State, USA, covering the period from 281 to -41 years before present. The dataset is part of the NOAA/WDS Paleoclimatology archive and was contributed by the NOAA National Centers for Environmental Information. The record was last updated in 1991.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate the tree-ring proxy record against known climate events within the 322-year time span.
• Analyze growth patterns in Pinus albicaulis (whitebark pine) from the Hart's Pass site for ecological studies.
• Compare this chronology with other regional tree-ring datasets to assess spatial climate patterns.

Strengths

• Provides a 322-year continuous chronology for climate proxy analysis.
• Archived and maintained by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Data is temporally stale, with a last update recorded in 1991.
• The geographic scope is limited to a single site (Hart's Pass, Washington).
• Specific parameters and measurement details require consulting external metadata.
