Swedish Tree Ring Chronology from 130 to -33 BP

Tree ring data from the Abisko Valley in Sweden, used for paleoclimate reconstruction. The chronology covers a 163-year period from 130 to -33 calendar years before present. The dataset was archived by NOAA's National Centers for Environmental Information in 1983.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate the chronology against other regional proxies to validate climate models for the period 130 to -33 BP.
• Analyze growth patterns in the Abisko Valley to infer local environmental stressors during the covered time span.
• Compare this Swedish tree-ring series with other ITRDB chronologies to assess spatial climate patterns in Scandinavia.

Strengths

• Data covers a specific 163-year time range from 130 to -33 calendar years BP.
• Sourced from the authoritative International Tree-Ring Data Bank (ITRDB) under NOAA's World Data Service.

Limitations

• The dataset is temporally stale, with a last update recorded in 1983, potentially lacking modern reanalysis.
• Limited geographic scope to a single valley (Abisko) in Sweden, reducing broad regional representativeness.
• Unknown sample size and replication depth of the underlying tree-ring measurements.
