Granite Mountain Tree-Ring Width Chronology from Washington (450-30 BP)

NOAA/WDS Paleoclimatology archives a tree-ring width chronology from Granite Mountain, Washington, USA. The data provides annual-resolution climate proxy records covering the period from 450 to 30 calendar years before present. This dataset was published by NOAA National Centers for Environmental Information.

Use Cases

• Calibrating past temperature or precipitation estimates using the tree-ring width time-series as a climate proxy.
• Analyzing decadal to centennial-scale climate variability in Washington state over the 480-year chronology.
• Cross-dating and validating other paleoclimate records from the PAGES North America 2K network using this standardized series.
• Studying the growth response of Tsuga mertensiana (TSME) trees to environmental stressors recorded in ring-width anomalies.

Strengths

• Data spans a 480-year period (450 to 30 BP), providing a multi-century climate record.
• Part of the standardized PAGES North America 2K network, ensuring methodological consistency for continental-scale studies.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends 30 years before present (circa 1920 AD), lacking recent decades.
• Sample size, replication, and site details are unknown without accessing full metadata.
• The last update recorded is 1980-01-01, indicating the core dataset is historical and not actively revised.
