Bavarian Tree Ring Chronology from 220 to 122 BC

Tree ring width measurements from Bavaria, Germany, used for climate reconstruction. The chronology covers a 99-year period from 220 to 122 calendar years before present. Data is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct historical temperature or precipitation patterns in Bavaria using annual tree ring width as a proxy.
• Calibrate regional climate models by comparing the tree ring chronology with other paleoclimate records for the period 220-122 BC.
• Analyze the frequency and severity of historical drought or growth stress events indicated by narrow ring sequences.
• Establish a dated chronology for archaeological or historical studies in the Regensburg region using the absolute dating provided by tree rings.

Strengths

• Data spans a continuous 99-year period (220-122 BC), providing a multi-decadal climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology, ensuring curation and metadata standards.

Limitations

• The sample size (number of tree cores or series) is unknown, which limits assessment of statistical robustness.
• Geographic coverage is limited to a single location in Bavaria, Germany, reducing regional representativeness.
• Data is temporally stale, with a last updated metadata date of 1828, indicating no recent revisions.
