Oregon Tree-Ring Width Chronology from 450 to -30 BP

450 to -30 calendar years before present (BP) of tree-ring width data from a site in Oregon, USA, used for paleoclimate reconstruction. This archived study is part of the NOAA/WDS Paleoclimatology collection and the PAGES North America 2K initiative. The data was contributed by Holmes and archived by NOAA National Centers for Environmental Information.

Use Cases

• Reconstructing past temperature or precipitation anomalies in Oregon using the tree-ring width time-series.
• Calibrating and validating regional climate models for the Pacific Northwest with the high-resolution proxy record.
• Analyzing long-term climate trends and extreme events over a ~480-year period from the dated ring-width chronology.
• Contributing to continental-scale climate reconstructions like PAGES 2K by integrating this site's chronology.

Strengths

• Time-series covers approximately 480 calendar years, providing a multi-century climate record.
• Data is part of the authoritative NOAA/WDS Paleoclimatology archive and the PAGES 2K network, ensuring scientific curation.

Limitations

• The dataset is temporally stale, with a last update date recorded as 1980-01-01.
• Geographic coverage is limited to a single site (Calamity Creek, Oregon), limiting regional representativeness.
• The raw description does not specify sample depth or replication, which is critical for assessing chronology confidence.
