Navaho Canyon Douglas Fir Tree Ring Chronology 500-13 BC

513-year tree ring chronology from Douglas fir trees in Navaho Canyon, Colorado, covering the period 500 to 13 calendar years before present. The dataset was archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program. The original study data was last updated in 1963.

Use Cases

• Reconstruct annual precipitation or temperature anomalies for Colorado using the tree ring width series.
• Calibrate radiocarbon dating sequences by cross-referencing the established tree ring chronology.
• Analyze the frequency of drought events in the pre-Columbian era from patterns in the ring width data.
• Study the growth response of Douglas fir (Pseudotsuga menziesii) to past climatic stressors recorded in the rings.

Strengths

• Covers a 513-year period from 500 to 13 BC, providing a long baseline.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with the last update recorded in 1963.
• Specific sample size, geographic precision, and measurement parameters are unknown from the description.
