NOAA/WDS Paleoclimatology archives a tree-ring chronology dataset from the Monarch Lake site in Colorado. The data provides a proxy climate record spanning 557 calendar years, from 520 to -37 years before present. NOAA National Centers for Environmental Information (NCEI) published this study, with an archival date of 1987.
Use Cases
- Reconstruct past temperature or precipitation anomalies using annual tree-ring width measurements.
- Calibrate the chronology against known climate events within the 557-year time period.
- Analyze growth patterns (e.g., ring density) as a proxy for historical environmental stress in Colorado.
Strengths
- Provides a 557-year continuous chronology for climate proxy analysis.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends 37 years before 1950 (the 'present' reference), limiting analysis of very recent climate.
- The dataset's last known update was in 1987, indicating potential staleness in metadata or methods.
- Specific sample size, replication, and measurement parameters are unknown from the provided description.
