Calamity Creek Tree-Ring Chronology from Oregon (554 to -32 BP)

Tree-ring width measurements from the Calamity Creek site in Oregon, United States, covering 586 calendar years from 554 to -32 years before present. The dataset was archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology. The record was last updated in 1982.

Use Cases

• Calibrating tree-ring width variations against instrumental climate records to reconstruct past temperature or precipitation.
• Analyzing the chronology for marker years (e.g., narrow rings) to date past climatic events or disturbances.
• Comparing this site chronology with others in the ITRDB (ITRDB OR009) to assess regional climate signals.
• Using the year-by-year ring-width series to model forest growth responses to environmental stressors over six centuries.

Strengths

• 586-year continuous chronology providing a multi-century climate proxy.
• Part of the International Tree-Ring Data Bank (ITRDB), ensuring standardized archiving and format.
• Specific geographic location (Oregon, USA) allows for localized climate analysis.

Limitations

• Data last updated in 1982, lacking modern revisions or potential new measurements.
• Unknown sample depth (number of trees/cores) limits assessment of chronology robustness.
• Calendar year coverage uses 'years before present' (BP) convention, requiring conversion for standard analysis.
