Chinook Pass Tree Ring Chronology for Paleoclimate Analysis

NOAA/WDS Paleoclimatology provides a tree-ring chronology from Chinook Pass, Washington. The data covers a period from 364 to -30 calendar years before present, collected as part of a Tree Ring study. This archived dataset is maintained by the NOAA National Centers for Environmental Information.

Use Cases

• Reconstruct past temperature or precipitation using the tree-ring width chronology as a climate proxy.
• Calibrate climate models by comparing the tree-ring time-series data with instrumental records for the region.
• Analyze long-term climate trends and extreme events from the 394-year span of the tree-ring record.
• Study the growth response of Tsuga mertensiana (TSME) trees to historical environmental changes at Chinook Pass.

Strengths

• Time series spans 394 calendar years (364 to -30 BP), providing a multi-century climate record.
• Data is archived and curated by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Dataset is temporally stale, with a last updated date of 1980-01-01, indicating no recent revisions.
• Specific sample size (number of tree cores), measurement parameters, and potential biases are not detailed in the provided description.
