North Carolina Tree Ring Chronology from 342 to 145 Years Before Present

Tree ring width data from the Jeffries Smokehouse site in North Carolina provides a 197-year chronology for paleoclimate analysis. The dataset was archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology. It covers the period from 342 to 145 calendar years before present.

Use Cases

• Reconstruct historical temperature or precipitation anomalies by analyzing annual tree ring width variations.
• Calibrate climate models by comparing the tree ring chronology proxy data with other paleoclimate records.
• Study the frequency of environmental stressors, such as droughts, evident in narrow ring sequences within the chronology.
• Perform cross-dating analysis by matching ring width patterns from this site with other regional chronologies to validate dating.

Strengths

• Chronology spans 197 consecutive years, providing a continuous environmental record.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's temporal coverage is limited to a specific 197-year window, not extending to modern or more ancient periods.
• Geographic scope is restricted to a single site in North Carolina, limiting regional generalizability.
• The 'last updated' metadata date of 1805-01 01 indicates potential staleness in metadata management.
