Lithuanian Tree-Ring Chronology From 99 To -45 BP

144 calendar years of tree-ring width data from Geruliai, Lithuania, provide a proxy climate record. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with the NCEI Tree Ring study type. The data collection was last updated in the NOAA system in 1995.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series as a climate proxy.
• Calibrate the tree-ring chronology against other regional paleoclimate records for the period 99 to -45 BP.
• Analyze growth patterns in the Geruliai site data to infer historical environmental stress events.
• Validate climate model simulations for the Baltic region using this high-resolution proxy time-series.

Strengths

• Covers a continuous 144-year period (99 to -45 BP) for high-resolution temporal analysis.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset is temporally stale, with its last recorded update in 1995.
• Geographic coverage is limited to a single site (Geruliai) in Lithuania, limiting spatial representativeness.
• Specific sample depth, measurement parameters, and potential uncertainties are not detailed in the provided metadata.
