Tree-ring width measurements from the Mount Washington site in Nevada, United States. The chronology covers a period from 450 to -30 calendar years before present. This paleoclimatology study is archived by the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series.
- Calibrate climate models by comparing the proxy chronology from site NV513 with instrumental records.
- Analyze growth anomalies in the ring-width series to identify extreme historical drought or wet periods.
- Cross-date the Mount Washington chronology with other regional tree-ring datasets to validate temporal coverage.
Strengths
- Time-series coverage spans 480 calendar years (450 to -30 BP).
- Data is part of the authoritative PAGES North America 2K network for climate reconstruction.
Limitations
- Temporal coverage ends at -30 BP (approximately 1980 AD), lacking recent decades.
- Single geographic site (Mount Washington, Nevada) limits regional representativeness.
- Sample size and replication statistics for the ring-width series are unknown.
