A tree-ring chronology from Ponderosa Pine (PSME) at Ruidosa Ridge, New Mexico, United States. The dataset provides annual growth measurements covering 282 years, from 260 to -22 calendar years before present. It is archived by the NOAA National Centers for Environmental Information World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past precipitation or drought indices by analyzing annual ring-width measurements.
- Calibrate climate models using the dated tree-ring series as a proxy for temperature variability.
- Study forest response to historical climate events through changes in growth patterns recorded in the rings.
- Cross-date this chronology with other regional series to build a longer, more reliable regional climate record.
Strengths
- Chronology spans 282 years, providing a multi-century climate proxy.
- Data is sourced from a specific tree species (Ponderosa Pine) at a defined geographic location (Ruidosa Ridge, NM).
- Archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -22 BP (approximately 1972 CE), making the record potentially outdated for recent climate studies.
- Limited to a single geographic site, which may not represent broader regional climate patterns.
- Sample size and replication statistics for the underlying tree cores are unknown from the provided metadata.
