Tree Ring Chronology from Karabatkak, Kyrgyzstan (300 to -45 BP)

NOAA/WDS Paleoclimatology archives a tree-ring chronology dataset from the Karabatkak site in Kyrgyzstan. The data provides proxy climate records covering the period from 300 to -45 calendar years before present. It was published by the NOAA National Centers for Environmental Information under its World Data Service.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree-ring width series.
• Calibrate climate proxy models using the dated chronology spanning 345 years.
• Study regional climate extremes by identifying marker years of exceptionally narrow or wide rings.
• Compare Central Asian dendroclimatic signals with other records using the geospatial location data.

Strengths

• Time series covers a 345-year period from 300 to -45 BP.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update recorded in 1995.
• Sample size and replication depth (number of tree cores) are unknown, limiting statistical confidence.
• Geographic coverage is limited to a single site (Karabatkak, Kyrgyzstan).
