Montana Tree-Ring Width Chronology from 750 to -37 BP

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

Use Cases

• Reconstruct past temperature or precipitation anomalies for the Montana region using the tree-ring width time-series.
• Calibrate climate models by comparing the tree-ring width chronology with instrumental climate records.
• Analyze long-term growth trends and responses to environmental stressors in Pseudotsuga menziesii.
• Cross-date and validate other tree-ring chronologies from the North American region using this reference series.

Strengths

• Time-series spans 787 years (750 to -37 BP), providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1987, indicating it is a static historical snapshot and may lack modern methodological refinements.
• Geographic coverage is limited to a single site (North Fork Ridge, Montana), reducing regional representativeness.
