Colorado Tree-Ring Width Chronology from 450 to -30 BP

NOAA/WDS Paleoclimatology archives a tree-ring width chronology from Frosty Park, Colorado. The data provides annual-resolution proxy climate records covering a 480-year period from 450 to -30 calendar years before present. This dataset is part of the NOAA National Centers for Environmental Information's Paleoclimatology collection under the World Data Service.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree-ring width variations.
• Calibrate and validate climate model simulations for the last 500 years using the proxy chronology.
• Study ecological response to historical climate events by examining growth suppression or release signals in the ring-width series.
• Establish a regional master chronology for Colorado by cross-dating this series with other local tree-ring collections.

Strengths

• Provides a continuous, annual-resolution climate proxy record spanning 480 years.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• The dataset's last update date is 1980-01-01, indicating it is a static, historical archive with no recent revisions.
• Specific sample depth, replication statistics, and measurement precision for the ring-width series are unknown from the provided metadata.
• Geographic coverage is limited to a single site (Frosty Park, Colorado), restricting broad spatial analysis.
