NOAA/WDS Paleoclimatology archives tree-ring width chronologies from two sites in Mexico. The data covers a period from 450 to -30 calendar years before present. This study is part of the PAGES North America 2K initiative and is maintained by the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct past climate variables like precipitation or temperature using the tree-ring width time-series.
- Calibrate and validate climate models for the North American region using the 480-year chronology.
- Analyze long-term ecological trends and forest growth responses using the site-specific ring width data.
- Correlate the Cerro Baraja and Los Angeles Sawmill chronologies with other regional paleoclimate proxies.
Strengths
- Chronology spans approximately 480 calendar years (450 to -30 BP).
- Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.
Limitations
- Sample size and replication depth for the tree-ring series are unknown.
- Temporal coverage ends at -30 BP, providing no data for the most recent ~2000 years.
- Geographic coverage is limited to two specific sites in Mexico.
