Swiss Larch Tree Ring Chronology from 146 to 45 BCE

191-year tree ring chronology from a Larch forest in Switzerland, covering the period from 146 to 45 years before present. The dataset was archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology. This record was last updated in 1995.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual ring_width measurements.
• Calibrate radiocarbon dating or synchronize other paleoclimate proxies using the established tree-ring chronology.
• Study forest growth responses to historical environmental events within the specified time_range.
• Validate climate model simulations for Western Europe using the high-resolution temporal data.

Strengths

• 191-year continuous chronology providing high-resolution temporal data.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1995, indicating potential staleness in metadata or availability.
• Specific sample depth, measurement parameters, and potential error ranges are unknown from the description.
• Geographic coverage is limited to a single site in Switzerland, reducing broad spatial representativeness.
