Swedish Tree-Ring Chronology from 147 to -42 BP

Tree-ring width measurements from Kaaresuvanto, Sweden provide a climate proxy record spanning 189 years from 147 to -42 calendar years before present. This paleoclimatology dataset is archived by the NOAA National Centers for Environmental Information under the World Data Service. The data was published in 1992.

Use Cases

• Calibrating climate models by comparing tree-ring width variations against known historical climate periods.
• Reconstructing past temperature or precipitation anomalies for Scandinavia using the tree-ring proxy series.
• Analyzing the frequency of extreme growth years within the 189-year chronology to identify past climatic events.

Strengths

• Covers a continuous 189-year period from 147 to -42 BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to 189 years, a relatively short period for long-term climate trend analysis.
• Data is geographically specific to a single site in northern Sweden, limiting regional generalizations.
• The dataset was last updated in 1992 and may not reflect more recent methodological standards.
