Kyrgyzstan Tree Ring Chronology from 604 to 45 BC

NOAA/WDS Paleoclimatology archives a tree ring chronology dataset from the Kyrgyzstan High Bon site. The data provides a 649-year record of tree growth from 604 to 45 calendar years before present. It was published by NOAA National Centers for Environmental Information in 1995.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree ring width chronology.
• Calibrate and validate climate models for Central Asia with the 649-year proxy record.
• Analyze growth anomalies in the tree ring series to identify extreme historical climate events.
• Study long-term environmental change and forest dynamics in Southcentral Asia from the dated series.

Strengths

• 649-year continuous time-series from 604 to 45 BC.
• Data is curated and archived by the NOAA World Data Service for Paleoclimatology, an authoritative source.

Limitations

• Data is temporally stale, last updated in 1995 and may lack modern methodological refinements.
• Geographic coverage is limited to a single site (JUSP - ITRDB KYRG002) in Kyrgyzstan.
• Specific measured parameters (e.g., ring width, density) and sample depth are not detailed in the provided metadata.
