Swiss tree ring data from the Lötschental region, covering a 316-year period from 268 to -48 calendar years before present. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with a study by Büntgen. It was last updated in 1998.
Use Cases
- Calibrating climate models using tree ring width as a proxy for past temperature or precipitation in Switzerland.
- Analyzing long-term climate trends by constructing a chronology from the 316-year time series of ring measurements.
- Cross-dating archaeological wood samples from Western Europe against the established Lötschental chronology.
- Investigating extreme climate events, such as volcanic winters or droughts, recorded in the annual tree ring sequence.
Strengths
- Covers a 316-year time period (268 to -48 BP) for long-term trend analysis.
- Sourced from NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with a last update in 1998.
- Geographic scope is limited to a single region (Lötschental, Switzerland).
- Sample size and replication level of tree cores are unknown.
