Norwegian Tree Ring Chronology From 465 to -28 BP

465 to -28 calendar years before present (BP) of tree ring width measurements from Lofoten, Norway, used for climate reconstruction. The dataset is part of the NOAA NCEI World Data Service for Paleoclimatology archive, contributed by F. Schweingruber. This specific study was archived in 1978.

Use Cases

• Reconstruct past temperature or precipitation anomalies using standardized tree ring width indices.
• Calibrate the chronology by cross-dating ring width patterns against other regional series.
• Analyze long-term climate trends and extreme events in Northern Norway over the 493-year period.
• Validate regional climate model outputs for the late Holocene period using proxy data.

Strengths

• Covers a 493-year period from 465 to -28 BP, providing a multi-century climate record.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology with documented metadata.

Limitations

• Data is temporally stale, last updated in 1978, and may not reflect modern methodological standards.
• Limited geographic scope to a single site (Lofoten Loedingen) in Norway, reducing regional representativeness.
• The raw sample depth and replication statistics per year are unknown, affecting confidence in early periods.
