Colorado Pumphouse Tree Ring Chronology from 630 to -49 BP

679-year tree ring chronology from the Pumphouse site in Colorado, United States, covering the period from 630 to -49 calendar years before present. The data was archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology. This study was last updated in 1999.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width index as a proxy.
• Calibrate regional climate models by comparing the chronology's growth patterns with known historical climate events.
• Analyze long-term ecological resilience and disturbance events, such as droughts, from the growth series.
• Establish a dated master chronology for the region to support the dating of other paleoenvironmental records.

Strengths

• Chronology spans 679 calendar years, providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data recency is low, with a last update in 1999, potentially missing modern analytical refinements.
• Geographic coverage is limited to a single site (Pumphouse) in Colorado, limiting regional representativeness.
