Barlow Pass Tree Ring Chronology for Climate Reconstruction

NOAA/WDS Paleoclimatology archives a tree ring chronology from Pseudotsuga menziesii (PSME) at Barlow Pass near Mount Hood, Oregon. The data covers a time period from 446 to -33 calendar years before present (BP), representing a multi-century paleoclimate record. This archived study was published by the NOAA National Centers for Environmental Information in 1983.

Use Cases

• Reconstructing historical temperature anomalies using tree ring width measurements as a proxy.
• Analyzing drought frequency and severity in the Oregon Cascades over the last 500 years based on growth ring patterns.
• Calibrating climate models with on-site proxy data from the 'tree ring' parameter for the Mount Hood region.
• Studying the response of Pseudotsuga menziesii (PSME) to climatic events recorded in the annual growth series.
• Investigating volcanic or seismic event impacts on forest growth using the high-resolution time-series data.

Strengths

• Time series covers approximately 480 calendar years, from 446 to -33 BP.
• Data is part of the authoritative NOAA/WDS Paleoclimatology archive and International Tree Ring Data Bank (ITRDB).
• Provides a site-specific chronology for a key species (Pseudotsuga menziesii) in a distinct geographic location.

Limitations

• Data freshness is low, with the last update recorded in 1983.
• Specific sample size (row count), column details, and measurement parameters are unknown from the provided metadata.
• Geographic coverage is limited to a single site at Barlow Pass, Oregon.
