Oregon Tree-Ring Width Chronology from 450 to -30 BP

Tree-ring width measurements from the Frederick Butte site in Oregon, USA, used for paleoclimate reconstruction. The chronology covers a period from 450 to -30 calendar years before present. Data is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past temperature or precipitation anomalies by calibrating tree-ring width series against modern instrumental records.
• Analyze the timing and magnitude of climatic events, such as droughts, within the 480-year chronology from Oregon.
• Validate regional climate model simulations for the Pacific Northwest using the proxy data from the Frederick Butte site.
• Cross-date and synchronize this JUOC-OR015 chronology with other tree-ring records to build a broader North American climate network.

Strengths

• Chronology spans 480 calendar years (450 to -30 BP), providing a multi-century climate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1980, indicating it may not reflect more recent methodological standards or corrections.
• Sample size, replication depth, and specific site details are unknown from the provided description.
