Oregon Tree-Ring Width Chronology from 750 to 37 BC

NOAA/WDS Paleoclimatology archives a tree-ring width chronology from Oregon, USA. The data provides annual-resolution climate proxy records covering 787 years, from 750 to 37 BC. The dataset was published by NOAA National Centers for Environmental Information in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies by calibrating tree-ring width measurements against instrumental records.
• Analyze the frequency and severity of drought events over the 787-year period using the annual tree-ring width series.
• Validate regional climate model simulations for the Pacific Northwest using the high-resolution proxy data from 750 to 37 BC.
• Study the growth response of trees to volcanic eruptions or other major climate forcings recorded in the ring-width chronology.

Strengths

• Provides 787 years of continuous, annual-resolution proxy data from 750 to 37 BC.
• Sourced from the authoritative NOAA National Centers for Environmental Information (NCEI) World Data Service.

Limitations

• Dataset is temporally stale, with a last update recorded in 1987.
• Limited geographic scope to a specific site in Oregon, USA, reducing broad applicability.
• Lack of accessible metadata on sample depth, species, or measurement protocols limits reproducibility.
