Drumhill Ridge Tree-Ring Chronology for Climate Reconstruction

278 to -40 calendar years before present (BP) of tree-ring data from a single site in Oregon, USA. This dataset, archived by NOAA's World Data Service for Paleoclimatology, is a dendrochronological record for paleoclimate studies. The data was contributed by author Wickman and last updated in the NOAA system in 1990.

Use Cases

• Reconstruct annual temperature or precipitation anomalies for Oregon from the tree-ring width parameter.
• Calibrate regional climate models by comparing the tree-ring chronology time series against instrumental records.
• Analyze growth patterns and extreme climate events captured in the PIPO (Pinus ponderosa) species record.
• Establish a dated chronology for the Drumhill Ridge site to support cross-dating with other regional tree-ring studies.

Strengths

• Covers a 318-year time period (278 to -40 BP) providing a multi-century climate proxy.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Includes specific geographic location data for Oregon, United States.

Limitations

• Temporal coverage ends at -40 BP, making the most recent data over 2000 years old and not directly comparable to modern instrumental periods.
• Data is from a single site (Drumhill Ridge) and a single species (PIPO), limiting spatial and ecological representativeness.
• Metadata and data structure details are not provided in the input, requiring external review of full study documentation.
