Pintlers Tree-Ring Width Chronology For Montana Climate Reconstruction

Tree-ring width measurements from the Pintlers site (LALY - MT119) in Montana, USA, provide a 787-year paleoclimate record from 750 to -37 calendar years before present. The dataset is archived by NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. This specific chronology was last updated in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies by calibrating tree-ring width series against instrumental climate records.
• Analyze the timing and magnitude of extreme climatic events, such as droughts, within the 787-year chronology.
• Validate regional climate model simulations for the North American interior using the high-resolution proxy data.
• Study long-term forest growth dynamics and resilience in Montana's ecosystems using the tree-ring parameter.

Strengths

• Covers a 787-year time period from 750 to -37 BP, providing a multi-century climate proxy.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -37 BP (approximately 1987 AD), lacking recent decades.
• Data is from a single site (Pintlers, Montana), limiting spatial representativeness.
• The last update was in 1987, indicating the methodology and metadata may not reflect current standards.
