Wyoming Tree Ring Width Chronology from 750 to 37 BP

A 787-year tree-ring width chronology from Wyoming, USA, covering the period from 750 to 37 calendar years before present. The dataset was archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. The data was last updated in the system in 1987.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree-ring width time-series.
• Calibrate and validate climate models by comparing simulated past conditions with the tree-ring proxy record.
• Analyze long-term ecological trends and forest growth responses to environmental changes recorded in the ring-width data.
• Study extreme historical events, such as droughts or cold periods, visible as anomalies in the ring-width chronology.

Strengths

• Provides a continuous 787-year proxy climate record.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The core data collection and last update occurred in 1987, making it temporally stale for recent analyses.
• Limited to a single geographic location (Wyoming, USA), reducing broad spatial applicability.
