Oregon Tree Ring Chronology From Long Prairie Spring

A tree ring chronology from a Ponderosa Pine (Pinus ponderosa) site at Long Prairie Spring in Oregon, USA, covering 478 years from 453 to -25 calendar years before present. The dataset is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. It was last updated in the NCEI system in 1975.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree-ring width time-series.
• Calibrate radiocarbon dating or other chronological methods using the precisely dated tree-ring sequence.
• Analyze long-term ecological growth patterns and responses to environmental stressors for the Ponderosa Pine species.
• Compare this local Oregon chronology with other regional tree-ring datasets to identify broader climate signals.

Strengths

• Covers a 478-year time period (453 to -25 BP).
• Provides a precisely dated chronology from a specific tree species (Pinus ponderosa) and location.

Limitations

• The dataset is temporally stale, with a last recorded update in 1975.
• The specific parameters and measurement details are not provided in the basic description, requiring metadata review.
