Mount Jefferson Tree-Ring Width Chronology from Nevada

NOAA/WDS Paleoclimatology archives a tree-ring width chronology from Mount Jefferson, Nevada. The data covers the period from 450 to -30 calendar years before present (BP). This dataset is part of the PAGES North America 2K initiative and was last updated in 1980.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series.
• Calibrate climate models by comparing the chronology data with instrumental records.
• Analyze climate extremes and event frequency over a multi-century timescale.
• Study ecological resilience by examining growth response patterns in the chronology.

Strengths

• Time-series covers a 480-year period (450 to -30 BP).
• Data is curated and archived by the NOAA National Centers for Environmental Information (NCEI).

Limitations

• Dataset is temporally stale, with a last update date of 1980.
• Specific sample size (row count) and measurement details are unknown.
