Mount Jefferson Tree Ring Chronology from 236 to -43 BP

236 to -43 calendar years before present (BP) of tree-ring width data from Tsuga mertensiana (TSME) trees at Mount Jefferson, Oregon, USA. This paleoclimatology dataset was archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was last updated in the NOAA system in 1993.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series as a climate proxy.
• Calibrate the Tsuga mertensiana (TSME) chronology against other regional paleoclimate records for cross-validation.
• Analyze climate trends and extreme events for the period 236 to -43 BP specific to the Mount Jefferson, Oregon location.

Strengths

• Covers a 279-year time period (236 to -43 BP) for climate analysis.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1993, indicating potential staleness and lack of recent curation.
• Sample size (number of tree cores or series) is unknown, which limits assessment of statistical robustness.
• Geographic coverage is limited to a single site at Mount Jefferson, Oregon.
