Yellow Mountain Ridge Tree-Ring Width Chronology From 750 BC

750 to -37 calendar years before present (BP) of tree-ring width data from a Pseudotsuga menziesii (PSME) site in Montana, USA. This paleoclimatology dataset is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was last updated in the repository in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series.
• Calibrate the tree-ring width chronology against instrumental climate records for the Montana region.
• Analyze the frequency of narrow rings (potential drought indicators) within the multi-century chronology.
• Compare this Pseudotsuga menziesii chronology with other regional tree-ring datasets for spatial climate pattern analysis.

Strengths

• Chronology spans approximately 787 years (750 to -37 BP), providing multi-century coverage.
• Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The data has not been updated in the repository since 1987, potentially missing modern reanalysis or calibration.
• The sample is from a single tree species (Pseudotsuga menziesii) at one site (MT114), limiting spatial representativeness.
• The calendar year BP scale requires careful conversion for alignment with standard historical or CE/BCE timelines.
