Boulder Creek Colorado Tree Ring Chronology from 83 to -32 BP

NOAA/WDS Paleoclimatology archives a tree-ring dataset from Schweingruber for Boulder Creek, Colorado. The data provides a chronology from 83 to -32 calendar years before present, hosted by the NOAA National Centers for Environmental Information. This study was last updated in 1982.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree-ring width series as a proxy.
• Calibrate climate models by comparing the tree-ring chronology against instrumental records for the Colorado region.
• Analyze growth anomalies in the PSME (Ponderosa Pine) species to identify extreme historical drought or cold periods.
• Perform cross-dating analysis with other ITRDB chronologies using the annual resolution of the ring-width data.

Strengths

• Chronology spans 115 years, from 83 to -32 calendar years before present.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short for paleoclimate studies at 115 years.
• Data is geographically limited to a single site (Boulder Creek, Colorado).
• The dataset is temporally stale, with a last documented update in 1982.
