Mt. Ashland Tree Ring Chronology from 211 BC to 33 AD

211 to -33 calendar years before present (BP) tree ring data from Mt. Ashland near Medford, Oregon. The dataset contains parameters related to tree rings, archived by NOAA's World Data Service for Paleoclimatology. The data was published by the NOAA National Centers for Environmental Information in 1983.

Use Cases

• Analyzing annual tree-ring width variations to reconstruct past climate conditions.
• Crossdating the Mt. Ashland chronology with other regional series to validate temporal coverage.
• Calibrating the 244-year time series against known historical climate events.
• Studying parameters like ring density or growth anomalies to infer local environmental stressors.

Strengths

• 244-year time series coverage from 211 BC to 33 AD.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• Unknown sample size (number of tree cores or individual series).
• Data is from a single geographic location (Mt. Ashland), limiting regional analysis.
• Last update was in 1983, potentially using outdated measurement or calibration methods.
