Wyoming Tree-Ring Width Chronology from 750 to 37 BCE

NOAA NCEI archives this paleoclimatology dataset containing tree-ring width measurements from the Anderson Ridge East site in Wyoming, USA. It provides a climate proxy record spanning from 750 to 37 years before present (BP). The data was compiled by NOAA's World Data Service for Paleoclimatology and was last updated in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree-ring width time-series as a climate proxy.
• Calibrate regional climate models using the precisely dated chronology from 750 to 37 BP.
• Study long-term ecological responses to climate change by examining growth patterns in the Wyoming tree-ring record.
• Perform cross-dating with other North American tree-ring chronologies to validate regional climate events.

Strengths

• Time-series covers a 713-year period (750 to 37 BP), providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Dataset was last updated in 1987, indicating potential staleness and lack of recent methodological improvements.
• Specific sample size (number of tree cores) and measurement details are not provided in the available metadata.
• Geographic coverage is limited to a single site (Anderson Ridge East, Wyoming), limiting broad spatial analysis.
