Wyoming Tree-Ring Width Chronology from Mount Everts

NOAA NCEI archives a paleoclimatology dataset of tree-ring width measurements from Mount Everts, Wyoming, USA. The chronology covers 787 years, from 750 to -37 calendar years before present. Data were contributed by researcher Graumlich and published via the NOAA World Data Service for Paleoclimatology in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Wyoming using the tree-ring width time-series.
• Calibrate climate models by comparing the ring-width chronology with other regional paleoclimate proxies.
• Analyze long-term growth trends and climatic stressors for the PSME (Pinus ponderosa) species at the Mount Everts site.
• Study extreme climatic events, such as droughts, by identifying narrow ring-width years within the 787-year record.

Strengths

• 787-year temporal coverage provides a multi-century climate record.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).
• Part of the standardized PAGES North America 2K network, facilitating continental-scale comparisons.

Limitations

• Data is temporally stale, with a last update date of 1987, potentially lacking modern reanalysis.
• Sample size (number of tree cores) and replication statistics are unknown from the provided metadata.
• Geographic scope is limited to a single site (Mount Everts, Wyoming), limiting regional generalization.
