North Dakota Tree-Ring Chronology from 274 to 40 BC

NOAA NCEI archives a tree-ring chronology dataset for North Dakota, United States. The data covers a 314-year period from 274 to 40 calendar years before present. It was published by the NOAA World Data Service for Paleoclimatology and last updated in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree-ring width measurements.
• Calibrate climate proxy models using the dated chronology spanning 314 years.
• Study regional climate extremes and drought frequency for North Dakota from 274 to 40 BC.
• Compare this tree-ring series with other paleoclimate proxies for the Northern Plains region.

Strengths

• Covers a specific 314-year time period (274 to 40 BC).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Focuses on a defined geographic location: North Dakota, USA.

Limitations

• Temporal coverage ends 40 BC, lacking modern or recent historical data.
• Dataset metadata indicates last update was in 1990, suggesting potential staleness.
• Specific sample size, measurement parameters, and data formats are not provided in the description.
