Tree ring width measurements from Vemdalskalet, Sweden, form a paleoclimate proxy record. The chronology covers a 196-year period from 168 to -28 calendar years before present. The data is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1978.
Use Cases
- Calibrate climate models using the tree-ring width time-series as a proxy for past temperature or precipitation in Sweden.
- Analyze growth anomaly patterns within the chronology to identify extreme historical climate events.
- Cross-date and validate other regional tree-ring chronologies using the established Vemdalskalet time-series.
- Reconstruct summer temperature or drought indices for Scandinavia based on the ring-width parameter.
Strengths
- Covers a continuous 196-year time period (168 to -28 BP).
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- The dataset's last update was in 1978, indicating it may not reflect modern analytical methods or corrections.
- The specific sample depth (number of tree cores) and measurement statistics are unknown from the provided metadata.
