Lake Minotaur Tree-Ring Chronology from 340 to -42 BP

Tree-ring width measurements from the Lake Minotaur site in Washington, USA, provide a paleoclimate record. The chronology covers 382 years, from 340 to -42 calendar years before present. Data were archived by NOAA's National Centers for Environmental Information World Data Service for Paleoclimatology and last updated in 1992.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series.
• Calibrate the chronology against other regional proxies using the calendar year BP dating.
• Analyze growth trends and climate sensitivity for Tsuga mertensiana (TSME) at the specified geographic location.

Strengths

• 382-year continuous time-series from 340 to -42 BP.
• Data curated and archived by NOAA NCEI's authoritative World Data Service for Paleoclimatology.

Limitations

• Data record ends 42 years before 1950, limiting overlap with the modern instrumental period.
• Single-site chronology from Washington state may not represent broader regional climate.
• Metadata indicates last update was in 1992, suggesting no recent revisions.
