Crater Lake West Medium Tree-Ring Chronology from 263 to -42 BP

Tree-ring width measurements from Tsuga mertensiana trees near Crater Lake, Oregon, USA. Data coverage spans 305 years from 263 to -42 calendar years before present. The dataset was archived by NOAA NCEI's World Data Service for Paleoclimatology, with a record last updated in 1992.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series.
• Calibrate radiocarbon dating curves by cross-referencing the absolute dated tree-ring chronology.
• Analyze growth patterns of Tsuga mertensiana in response to documented volcanic events from the Crater Lake region.
• Compare this mid-elevation site chronology with other regional tree-ring records to study spatial climate patterns.

Strengths

• 305-year continuous chronology providing multi-century climate context.
• Data originates from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Precise temporal coverage defined as calendar years before present (263 to -42 BP).

Limitations

• Record last updated in 1992, indicating potential staleness and lack of recent methodological revisions.
• Sample size, replication depth, and specific measurement parameters are unknown from the description.
• Geographic coverage is limited to a single site at Crater Lake, Oregon.
