Swedish Tree Ring Chronology from 106 to -46 BP

Tree ring data from Gullhult, Sweden, covering a 152-year period from 106 to -46 calendar years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1996. It is associated with the ITRDB site code SWED321.

Use Cases

• Reconstruct past temperature or precipitation anomalies from tree-ring width measurements.
• Calibrate and validate climate models using the 152-year proxy record.
• Analyze growth patterns in Pinus sylvestris (PISY) trees for ecological studies.
• Cross-date and synchronize this chronology (SWED321) with other regional tree-ring datasets.

Strengths

• Data spans a specific 152-year period (106 to -46 BP).
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Geographically precise location in Sweden, Scandinavia.

Limitations

• Temporal coverage is relatively short (152 years) for long-term climate trend analysis.
• Data is temporally stale, with a last recorded update in 1996.
• Unknown sample size (row count) and specific measurement parameters.
