Salmon River Valley Douglas Fir Tree Ring Chronology

Calendar years 815 to -45 BP (Before Present) provide tree-ring width data for Douglas Fir (PSME) from the Salmon River Valley in Idaho. The dataset is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was last updated in 1995.

Use Cases

• Analyze climate signals by correlating tree-ring width variations with known historical climate events.
• Establish a regional reference chronology for Douglas Fir by crossdating the ring-width series.
• Reconstruct past temperature or precipitation anomalies using the tree-ring proxy data.
• Validate other paleoclimate proxies by comparing the tree-ring chronology with sediment or ice core records.

Strengths

• Time-series spans approximately 860 calendar years, providing a long-term climate proxy.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update date of 1995.
• Geographic coverage is limited to a single valley in Idaho, reducing generalizability.
• Specific data parameters and sample sizes are not provided in the description.
