Lithuanian Tree Ring Chronology from 89 to -37 BP

NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Dotnuva site in Lithuania. The data provides a temporal record from 89 to -37 calendar years before present (BP), created by the NOAA National Centers for Environmental Information. This study was last updated in the repository in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology as a proxy.
• Calibrate radiocarbon dating or other chronological models for the region using the established year-by-year timeline.
• Analyze the frequency of environmental stress events recorded in the ring density or other wood anatomical parameters.
• Compare this Northern European chronology with other regional series to study large-scale climate teleconnections.

Strengths

• Covers a specific 126-year period (89 to -37 BP) useful for focused chronological studies.
• Sourced from the authoritative NOAA National Centers for Environmental Information and World Data Service.

Limitations

• The dataset's last known update was in 1987, indicating it may not reflect modern reanalysis or newer methodologies.
• Specific parameters like ring width, density, or isotopic measurements are not detailed in the provided metadata.
• Geographic coverage is limited to a single site (Dotnuva, Lithuania), reducing regional generalizability.
