Hart's Pass Tree Ring Chronology for Paleoclimate Analysis

Tree ring data from Washington, USA, covers a 306-year period from 265 to -41 calendar years before present. This paleoclimatology study is archived by NOAA's National Centers for Environmental Information. The data was last updated in the repository in 1991.

Use Cases

• Reconstruct past temperature or precipitation anomalies using tree-ring width measurements.
• Calibrate climate models by comparing the chronology with other proxy records from the same time period.
• Analyze growth patterns to identify extreme climate events like droughts within the 306-year span.

Strengths

• 306-year temporal coverage provides a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last repository update in 1991.
• Geographic coverage is limited to a single site (Hart's Pass) in Washington.
