Mount Asahidake Tree Ring Chronology from 418 to 47 BC

Tree ring width measurements from Mount Asahidake in Hokkaido, Japan, provide a paleoclimate record. The chronology spans 465 years, from 418 to 47 calendar years before present. The dataset was archived by NOAA's National Centers for Environmental Information and last updated in 1997.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree ring width variations.
• Calibrate and validate climate models using the 465-year proxy record from Hokkaido.
• Study the frequency of extreme climatic events in Eastern Asia by identifying marker years in the ring series.
• Cross-date and synchronize this chronology with other regional tree ring datasets to improve spatial climate reconstructions.

Strengths

• Chronology covers a continuous 465-year period from 418 to 47 BC.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1997, indicating potential staleness in metadata or availability.
• Specific measurement parameters, sample depth, and statistical quality metrics are not provided in the input.
