631 to -49 calendar years before present of tree ring width measurements from ponderosa pine (PSME) trees at the Almont Triangle site in Colorado. The dataset is a dendrochronological series archived by NOAA's World Data Service for Paleoclimatology. Data was published by the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct annual precipitation or temperature anomalies for Colorado using tree ring width as a proxy.
- Calibrate the chronology against known climate events by analyzing the time-series of ring measurements.
- Study growth patterns and climate sensitivity of ponderosa pine (PSME) in a specific Colorado location.
- Cross-date and validate other tree ring records from the southwestern United States using this established chronology.
Strengths
- Time-series covers approximately 680 years, from 631 to -49 calendar years before present.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -49 BP, limiting analysis of the most recent centuries.
- Data is geographically limited to a single site (Almont Triangle, Colorado).
- The dataset's last known update was in 1999, indicating potential staleness.
