Wyoming Tree Ring Chronology for Climate Reconstruction

NOAA/WDS Paleoclimatology archives a tree ring chronology dataset from the Pedro Mountains, Alcova, and Seminoe areas in Wyoming. The data provides parameters for climate reconstruction covering a period from 414 to -14 calendar years before present. NOAA National Centers for Environmental Information (NCEI) maintains this archived study.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree ring width parameter.
• Calibrate climate models using the high-resolution time-series data spanning over 400 years.
• Study local climate extremes in Wyoming by examining the annual resolution of the tree ring record.
• Perform cross-dating analysis with other regional chronologies using the established calendar year timeline.

Strengths

• Data covers a specific 428-year time period (414 to -14 BP) for detailed temporal analysis.
• Sourced from NOAA NCEI, an authoritative repository for paleoclimate data.

Limitations

• The dataset's last update was in 1964, indicating the core data is over 60 years old.
• Geographic scope is limited to specific sites in Wyoming, reducing broad regional applicability.
• Unknown sample size (row count) and specific measured parameters beyond 'tree ring'.
