Colorado Tree Ring Chronology from 815 to 49 BCE

Tree ring width measurements from a single site in Colorado provide a climate proxy record spanning 864 years. The NOAA National Centers for Environmental Information archives this paleoclimatology study for climate reconstruction research. Data was last updated in the public archive in 1999.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width time-series.
• Calibrate the chronology against known historical climate events using the provided calendar years before present (BP) index.
• Compare this PSME (Pinus strobiformis) site chronology with other ITRDB records to assess regional climate signals.

Strengths

• Time series covers a substantial 864-year period from 815 to 49 BCE.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset is from a single tree species at one location (Land's End, Colorado), limiting spatial representativeness.
• Record ends 49 BCE, requiring gap analysis to connect with more recent climate reconstructions.
• Metadata and specific measurement parameters are not detailed in the provided description.
