Dodger Point Tree Ring Chronology From Washington State

140 annual tree-ring measurements from 100 to -40 calendar years before present provide a climate proxy record. The data is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program. This specific chronology was last updated in the public record in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the annual ring-width time-series.
• Calibrate the tree-ring chronology against other paleoclimate proxies for the 140-year period.
• Analyze growth patterns in Abies lasiocarpa (ABLA) trees from a specific site in Washington state.

Strengths

• Covers a specific 140-year period in the past, providing a focused temporal snapshot.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• The dataset is temporally stale, with a last updated date of 1990, indicating it is a static archive.
• The geographic coverage is limited to a single tree-ring site (Dodger Point) in Washington.
