Mount Hopkin's Tree Ring Chronology from 230 to -37 BP

NOAA/WDS Paleoclimatology archives a tree ring chronology for Pinus ponderosa (PIPO) from Mount Hopkin, Arizona. The dataset provides a time series covering 267 years, from 230 to -37 calendar years before present. NOAA National Centers for Environmental Information (NCEI) published this study, with a last update recorded in 1987.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree-ring width chronology.
• Calibrate and validate climate models by comparing the 267-year proxy record with instrumental data.
• Analyze growth patterns and extreme events (e.g., droughts) within the specified time range for ecological studies.
• Cross-date and validate other tree-ring chronologies from the Arizona region using this established series.

Strengths

• Time series spans 267 calendar years (230 to -37 BP), providing a multi-century climate proxy.
• Data is archived and curated by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data recency is limited, with a last documented update in 1987, potentially missing modern analytical refinements.
• Geographic coverage is restricted to a single site (Mount Hopkin, Arizona), limiting regional representativeness.
• Specific parameters, measurement units, and sample depth (number of trees) are not detailed in the provided description.
