Thornton Lakes Tree Ring Chronology From Washington State

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Thornton Lakes High site in Washington, USA. The dataset provides parameters for dendroclimatic reconstruction, covering a period from 185 to -42 calendar years before present. The data was published by NOAA National Centers for Environmental Information in 1992.

Use Cases

• Reconstruct past temperature or precipitation using tree-ring width parameters as a climate proxy.
• Calibrate the chronology against known climate events within the 227-year time period coverage.
• Analyze growth patterns in Tsuga mertensiana (TSME) trees from the specific geographic location in Washington.

Strengths

• Data spans a 227-year period (185 to -42 BP), providing a multi-century climate record.
• Archived by the authoritative NOAA National Centers for Environmental Information (NCEI) under the World Data Service.

Limitations

• Temporal coverage ends at -42 BP, indicating the dataset is not updated with recent decades.
• The last metadata update was in 1992, suggesting potential staleness in documentation or methods.
