Russian Tree Ring Chronology From 218 to -40 BP

Tree ring width measurements from the Verhnaja Toima site in Russia provide a 258-year paleoclimate record. The dataset, archived by NOAA's World Data Service for Paleoclimatology, covers the period from 218 to -40 calendar years before present. Data collection and archiving were managed by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree ring width variations.
• Calibrate radiocarbon dating or other chronological models using the dated tree ring sequence.
• Study the response of boreal forest growth to historical climate events documented in the ring record.
• Compare this Russian tree ring chronology with other proxy records to analyze regional climate patterns.

Strengths

• 258-year continuous time series of tree ring data.
• Geographically specific data from a single site (Verhnaja Toima, Russia).

Limitations

• Sample size and replication statistics are unknown.
• Data is temporally stale, with a last update recorded in 1990.
• The dataset covers a relatively short period for paleoclimate studies.
