Khadyta River Tree-Ring Chronology for Paleoclimate Reconstruction

168 tree-ring width measurements from the Khadyta River region in Russia, spanning 208 years from 168 to -40 calendar years before present. This paleoclimatology dataset was archived by NOAA's National Centers for Environmental Information under the World Data Service. The data collection was last updated in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a climate proxy.
• Calibrate the tree-ring series against instrumental records to develop transfer functions for climate variables.
• Analyze the frequency of narrow rings (indicating stress years) to identify historical drought or cold events in the region.
• Compare this chronology with other ITRDB series from Russia to study spatial patterns of past climate extremes.
• Use the dated series to validate or extend climate model simulations for the period 168 to -40 BP.

Strengths

• Time series covers a 208-year period from 168 to -40 BP, providing a multi-century climate record.
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA/NCEI.

Limitations

• Temporal coverage ends at -40 BP (40 BCE), making it less directly comparable to very recent instrumental periods.
• Sample size and replication statistics for the tree-ring measurements are unknown from the provided metadata.
• Data is from a single geographic location (Khadyta River, Russia), limiting spatial representativeness.

Collection Method

Tree-ring cores collected and measured using standard dendrochronological techniques, archived as part of the ITRDB.

Time Range

168 to -40 calendar years before present (BP).

Freshness

Last updated in 1990; the underlying data collection is likely historical and not actively updated.
