Mount Hood Tree Ring Chronology from 149 to -42 BP

NOAA/WDS Paleoclimatology archives a tree-ring chronology from Mount Hood, Oregon, USA. The dataset covers a time period from 149 to -42 calendar years before present. It was published by the NOAA National Centers for Environmental Information in 1992.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree-ring width chronology.
• Calibrate the tree-ring chronology against known climate events within the 191-year time span.
• Analyze growth patterns in Abies lasiocarpa (ABLA) trees from the Mount Hood site for ecological studies.
• Compare this ITRDB series (OR080) with other regional chronologies to assess spatial climate patterns.

Strengths

• Data spans 191 calendar years (149 to -42 BP), providing a multi-century record.
• Curated and archived by the authoritative NOAA National Centers for Environmental Information (NCEI).
• Part of the International Tree-Ring Data Bank (ITRDB), ensuring standardized format and metadata.

Limitations

• Temporal coverage is limited to 191 years, which is relatively short for some paleoclimate studies.
• Data is geographically specific to a single site (Mount Hood, Oregon), limiting broad spatial analysis.
• The dataset was last updated in 1992, indicating potential staleness and lack of recent methodological improvements.
