Alakurtti Pine Tree Ring Chronology from 251 to -42 BP

Tree ring width measurements from Scots Pine in Alakurtti, Russia, provide a 293-year climate proxy record. The dataset was archived by NOAA's World Data Service for Paleoclimatology and last updated in 1992. It is part of the International Tree-Ring Data Bank collection for Eastern Europe.

Use Cases

• Reconstruct past temperature or precipitation anomalies by calibrating tree ring width series against instrumental records.
• Analyze growth response and climate sensitivity of Scots Pine (PISY) in a boreal Russian environment.
• Cross-date and validate other tree ring chronologies from Eastern Europe using the established ITRDB RUSS125 series.
• Study long-term ecological trends and forest resilience across a nearly 300-year period ending 42 years before present.

Strengths

• Covers a 293-year time period from 251 to -42 calendar years BP.
• Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA.

Limitations

• Data last updated in 1992, potentially lacking modern methodological refinements.
• Specific sample size, replication statistics, and measurement parameters are unknown from the provided metadata.
• Geographic coverage is limited to a single site in Alakurtti, Russia.
