Tree Ring Chronology from Popigay Russia for Paleoclimate Study

NOAA's World Data Service archives this tree-ring chronology from the Popigay site in Russia, covering a 76-year period from 36 to -40 calendar years before present. The dataset was contributed by Schweingruber and is managed by NOAA National Centers for Environmental Information. It was last updated in the NOAA system in January 1990.

Use Cases

• Calibrating climate proxy models using the tree-ring width time-series from the Popigay site.
• Analyzing inter-annual climate variability in Eastern Europe during the 76-year period covered by the chronology.
• Cross-dating and validating other paleoclimate records from Russia using this ITRDB-standardized series.
• Reconstructing local temperature or precipitation anomalies from the ring-width parameter data.

Strengths

• Data is archived and standardized under the International Tree-Ring Data Bank (ITRDB) format.
• Provides a 76-year continuous chronology (from 36 to -40 BP) for a specific geographic site.
• Managed by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last known update was in 1990, indicating potential staleness in metadata or availability.
• Specific parameters, sample depth, and measurement details are unknown without accessing full metadata.
• Geographic coverage is limited to a single site (Popigay, Russia).
