German Tree Ring Chronology from 106 to -45 BP

NOAA's World Data Service for Paleoclimatology archives this tree ring chronology from the Sirnitz SW site in Germany. The dataset covers a 151-year period from 106 to -45 calendar years before present. It was contributed by Schweingruber and last updated in 1995.

Use Cases

• Calibrating radiocarbon dates for the 1st century BCE using the tree-ring width series.
• Reconstructing past temperature or precipitation anomalies for Western Europe from the ring-width parameter.
• Analyzing growth patterns and environmental stressors for Abies alba (ABAL) trees in the specified geographic location.
• Comparing this ITRDB GERM047 chronology with other European tree-ring records to identify regional climate signals.

Strengths

• Data originates from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Covers a specific 151-year time period (106 to -45 BP) with clear temporal bounds.
• Includes metadata with parameter and study location details for verification.

Limitations

• Temporal coverage is limited to a short 151-year window, restricting analysis of long-term trends.
• Data is geographically limited to a single site (Sirnitz SW, Germany), reducing regional generalizability.
• The dataset is temporally stale, with a last update date of 1995.
