Kyrgyzstan Tree Ring Chronology from 793 to 45 BCE

Tree ring width chronology data from the High Mur site in Kyrgyzstan, Southcentral Asia. The chronology covers 838 years, from 793 to 45 years before present (BCE). This archived paleoclimatology study was published by NOAA's National Centers for Environmental Information in 1995.

Use Cases

• Reconstruct past temperature or precipitation anomalies in Southcentral Asia using the tree ring width chronology.
• Calibrate regional climate models by comparing the tree ring proxy data with instrumental records for overlapping periods.
• Analyze the frequency of extreme climatic events, such as droughts, evident in the tree ring series over the 838-year span.
• Cross-date and validate other tree ring chronologies from the Central Asian region using this reference series.

Strengths

• 838-year continuous chronology from 793 to 45 BCE provides a long-term climate proxy.
• Data is archived and curated by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1995, potentially missing more recent methodological refinements.
• Sample size and replication statistics for the underlying tree cores are unknown, affecting confidence intervals.
