NOAA's Paleoclimatology archive provides a tree-ring chronology from the Lake Ånn Basin in Sweden. The data covers a period from 173 to -46 calendar years before present. This study was archived by the NOAA National Centers for Environmental Information in 1996.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
- Calibrate climate models by comparing the proxy tree-ring series with instrumental records for the region.
- Analyze long-term environmental trends in Scandinavia from the dated tree-ring sequences.
- Study the response of pine (PISY) growth to historical climate events within the specified time range.
Strengths
- Data spans 219 years of historical coverage (173 to -46 BP).
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -46 BP, providing no data for recent centuries.
- Geographic scope is limited to a single basin in Sweden.
- Data was last updated in 1996, indicating potential staleness in metadata or access methods.
