Hart's Pass Tree Ring Chronology for Climate Reconstruction

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Hart's Pass, Washington. The data provides annual-resolution climate proxy records spanning 141 years, from 99 to -42 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this study, with an archival date of 1992.

Use Cases

• Reconstruct past temperature or precipitation using annual tree-ring width measurements as a proxy.
• Calibrate climate models by comparing the tree-ring chronology with instrumental records for the region.
• Analyze growth trends of Abies lasiocarpa (ABLA) in response to historical climate events documented in the series.
• Establish a dated chronology for cross-referencing with other paleoclimate archives from the Northwestern United States.

Strengths

• Data covers a 141-year time period (99 to -42 BP), providing a multi-decadal climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to 141 years, which is relatively short for some paleoclimate analyses.
• Data is geographically specific to a single site (Hart's Pass, Washington), limiting regional generalizations.
• The dataset is temporally stale, with no updates indicated since its archival in 1992.
