Tree ring width measurements from Douglas Fir (Pseudotsuga menziesii) trees at Echo Amphitheater, New Mexico, provide a climate proxy record. The chronology spans 610 years, from 588 to -22 calendar years before present. NOAA National Centers for Environmental Information archived this paleoclimatology study in 1972.
Use Cases
- Reconstruct past drought severity by analyzing annual tree ring width variations.
- Calibrate regional climate models using the 610-year proxy record from Douglas Fir samples.
- Study local climate anomalies by comparing this site's ring widths to other southwestern chronologies.
- Establish a dated master chronology for the Echo Amphitheater site using the measured ring sequences.
Strengths
- 610-year temporal coverage provides a multi-century climate proxy.
- Data is archived and curated by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with a last update recorded in 1972.
- The geographic scope is limited to a single site in New Mexico.
- Specific sample count, measurement parameters, and data formats are not provided in the description.
