Idaho Tree-Ring Width Chronology From 750 To -37 BP

NOAA's National Centers for Environmental Information provides a tree-ring width chronology from Railroad Ridge, Idaho, USA. The data covers a period from 750 to -37 calendar years before present (BP), representing over 787 years of paleoclimatic history. This archived study was contributed by an author named Perkins and last updated in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Idaho using the tree-ring width parameter as a climate proxy.
• Calibrate regional climate models by comparing the tree-ring width time series against other paleoclimate records for the North America 2K network.
• Analyze the frequency and magnitude of climatic extremes, such as droughts, within the 787-year span captured by the chronology.
• Validate the PAGES North America 2K Version reconstruction for the Idaho region using this site-specific tree-ring dataset.

Strengths

• Covers a long temporal span of over 787 years (750 to -37 BP).
• Part of the standardized PAGES North America 2K network, facilitating continental-scale comparisons.
• Hosted and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update recorded in 1987.
• The dataset's sample size, replication, and specific site characteristics are unknown from the provided metadata.
• Geographic coverage is limited to a single site (Railroad Ridge) in Idaho.
