Douglas Fir Tree Ring Chronology from The Dalles, Washington

NOAA/WDS Paleoclimatology archives a tree ring chronology for Douglas Fir (PSME) from The Dalles, Washington. The data provides a proxy climate record covering 349 to -30 calendar years before present. This dataset is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation using annual tree-ring width measurements as a proxy.
• Calibrate climate models by comparing the tree-ring chronology with instrumental records for the region.
• Analyze growth patterns and climate sensitivity of Douglas Fir (PSME) from the specified geographic location.
• Study long-term environmental changes over a 379-year period captured in the ring series.

Strengths

• Data spans 379 calendar years, providing a multi-century climate proxy.
• Sourced from the authoritative NOAA National Centers for Environmental Information (NCEI).
• Includes precise geographic location metadata for contextual analysis.

Limitations

• Temporal coverage ends at -30 BP (approximately 1980 CE), with no recent updates.
• Sample size, replication, and measurement specifics are unknown from the provided metadata.
• Potential geographic bias limited to a single site (The Dalles, Washington).
