Scatter Lake Tree Ring Width Chronology for North American Climate Reconstruction

NOAA's National Centers for Environmental Information provides a tree-ring width chronology from Scatter Lake, Washington, USA. The data covers a 480-year period from 450 to -30 calendar years before present. This archived paleoclimatology study is part of the PAGES North America 2K initiative.

Use Cases

• Reconstruct annual temperature or precipitation anomalies from tree-ring width measurements.
• Calibrate climate models by comparing the tree-ring width time series with simulated past climate data.
• Analyze the frequency and severity of past drought events using the ring width chronology as a proxy.
• Study ecological resilience by correlating the tree-ring growth index with known historical climate events.

Strengths

• Data spans a continuous 480-year period, providing a multi-century climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Part of the standardized PAGES North America 2K network for continental-scale analysis.

Limitations

• Temporal coverage ends 30 years before present (circa 1980), lacking recent decades.
• Single-site chronology from Washington state limits spatial representativeness.
• Raw sample depth and replication statistics for the chronology are not provided in the input.
