Sarekungey Tree Ring Chronology For Paleoclimate Reconstruction

145 calendar years of tree ring data, from 100 to -45 years before present, provide a proxy record for historical climate conditions. The dataset contains parameters from tree rings, archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This study was last updated in 1995.

Use Cases

• Calibrating climate models using the tree-ring width time-series as a proxy for past temperature or precipitation.
• Analyzing growth anomaly patterns within the chronology to identify extreme historical climate events.
• Cross-dating the Sarekungey chronology with other regional tree-ring records to validate temporal coverage.
• Studying the response of tree-ring parameters to documented volcanic or solar forcing events within the 145-year period.

Strengths

• Covers a specific 145-year time period (100 to -45 BP) for focused temporal analysis.
• Archived and maintained by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short (145 years) compared to other paleoclimate proxy records.
• Data is geographically limited to a single site in Russia (Sarekungey, Kirgistan), reducing regional representativeness.
• The dataset has not been updated since 1995, potentially lacking modern methodological refinements.
