NOAA/WDS Paleoclimatology archives a tree ring chronology dataset from the Kirisky Pass site in the Altai region of Russia. The data provides a time series covering the period from 209 to -44 calendar years before present. This study was contributed to the International Tree-Ring Data Bank (ITRDB) and last updated by NOAA NCEI in 1994.
Use Cases
- Reconstructing past temperature or precipitation anomalies in the Altai region using the tree ring width chronology.
- Calibrating and validating climate models by comparing the tree ring proxy record with instrumental data for overlapping periods.
- Analyzing long-term climate trends and extreme events, such as droughts, by examining the annual resolution of the ring width series.
- Conducting cross-dating studies with other ITRDB chronologies from the region to verify the temporal accuracy of the Kirisky Pass record.
Strengths
- Provides a continuous, annually resolved proxy climate record spanning 253 years.
- Data is archived and standardized through the International Tree-Ring Data Bank (ITRDB), ensuring a consistent format.
Limitations
- Temporal coverage ends at -44 BP, making the most recent data over two millennia old and not directly applicable to modern climate studies.
- The dataset is geographically limited to a single site (Kirisky Pass), which may not represent broader regional climate patterns.
- The last update was in 1994, indicating the metadata and associated documentation may be outdated.
