Japanese Tree Ring Chronology from 532 to -48 BP

Tree ring width measurements from the Onnebetsu site in Japan provide a proxy climate record. The chronology covers a 580-year period from 532 to -48 calendar years before present. NOAA National Centers for Environmental Information archived this paleoclimatology study.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing tree ring width variations over the 580-year chronology.
• Calibrate radiocarbon dating or other chronological models using the dated tree ring series from Japan.
• Study extreme climate events or volcanic impacts by identifying marker years of suppressed growth in the ring width time series.
• Compare the Onnebetsu site chronology with other regional tree ring datasets to analyze spatial climate patterns.

Strengths

• Chronology spans 580 calendar years, providing a multi-century climate proxy.
• Data is curated and archived by NOAA's World Data Service for Paleoclimatology, an authoritative source.

Limitations

• The dataset's last update was in 1998, indicating potential staleness in metadata or availability.
• Sample size, replication, and specific measurement parameters are unknown from the provided description.
• Geographic coverage is limited to a single site (Onnebetsu) in Japan.
