Swedish Lapland Tree-Ring Chronology from 397 to -24 BP

NOAA's World Data Service for Paleoclimatology archives a tree-ring chronology from Arjeplog, Lapland, Sweden. The data covers a 421-year period from 397 to -24 calendar years before present. The National Centers for Environmental Information (NCEI) compiled and published this record in 1974.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the annual tree-ring width series.
• Calibrate climate models for northern Europe using the dated proxy record spanning several centuries.
• Study the frequency of extreme growth years, indicated by narrow or wide rings, to identify past climatic events.
• Cross-date and validate other tree-ring chronologies from the Scandinavian region using this master chronology.

Strengths

• Covers a specific 421-year period from 397 to -24 BP.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, last updated in 1974.
• Specific sample size, measurement parameters, and file formats are unknown.
