Grindelwald Tree Ring Chronology from 176 to 45 BC

221 years of tree ring data from the Grindelwald Süd site in Switzerland, covering the period from 176 to 45 BC. This paleoclimatology study is archived by the NOAA National Centers for Environmental Information under its World Data Service. The dataset was last updated in 1995.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree ring width series.
• Calibrate climate models using the precisely dated chronology from 176 to 45 BC.
• Study ecological responses to historical climate events using the tree ring parameter data.
• Compare this Alpine tree ring record with other regional proxy datasets for climate signal validation.

Strengths

• Time series covers a continuous 221-year period in the pre-Common Era.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update date of 1995.
• Geographic coverage is limited to a single site in the Swiss Alps.
• Specific parameters, sample size, and measurement methods are not detailed in the provided description.
