Hart's Pass Tree Ring Chronology for Climate Reconstruction

236 calendar years of tree-ring data from 194 to -42 years before present (BP), covering a period from the pre-industrial era into the past. This dataset contains parameters of tree rings from the Abies lasiocarpa (ABLA) species at Hart's Pass, Washington, USA, archived by NOAA NCEI's World Data Service for Paleoclimatology. The data was last updated in the repository in 1992.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
• Calibrate climate models by comparing the tree-ring time-series data with instrumental records for the overlapping period.
• Analyze growth patterns and climate sensitivity of Abies lasiocarpa (ABLA) trees at a high-elevation site in Washington.

Strengths

• Covers a 236-year time period (194 to -42 BP), providing a multi-century climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last repository update date of 1992, potentially missing newer methodological corrections.
• Geographic coverage is limited to a single site (Hart's Pass, Washington), limiting regional representativeness.
• Specific sample depth, measurement parameters, and data quality metrics are not provided in the available description.
