Siberian Tree Ring Chronology From Kodarpass (235 to -46 BP)

NOAA's World Data Service for Paleoclimatology archives this tree-ring dataset from the Kodarpass site near Lake Baikal, Russia. The chronology spans 281 years, from 235 to -46 calendar years before present. It was created by Schweingruber and last updated in the NOAA NCEI system in 1996.

Use Cases

• Calibrating climate models by comparing reconstructed temperature or precipitation proxies from ring-width measurements against model outputs for the 235 to -46 BP period.
• Analyzing growth anomaly years within the 281-year chronology to identify extreme climate events like droughts or cold periods in Siberian history.
• Cross-dating this Kodarpass chronology with other ITRDB RUSS169 series to build a regional composite climate record for Eastern Europe.
• Studying the response of tree growth at this specific geospatial location to climate forcing before present.

Strengths

• Covers a specific 281-year time period from 235 to -46 calendar years BP.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA NCEI.
• Provides a geographically precise record for a site near Lake Baikal in Russia.

Limitations

• Temporal coverage is limited to 281 years, a relatively short span for some paleoclimate studies.
• Data is temporally stale, with a last recorded update in 1996, potentially lacking modern reanalysis.
• Unknown sample depth (number of cores/trees) limits assessment of statistical robustness.
