Wyoming Tree Ring Chronology from 460 to -15 Years Before Present

NOAA's Paleoclimatology archive provides a tree-ring chronology from the Elbow Campground site in Jackson, Wyoming. The data covers a period from 460 to -15 calendar years before present, measured from Douglas-fir (Pseudotsuga menziesii) trees. This dataset was published by the NOAA National Centers for Environmental Information in 1965.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree-ring width measurements.
• Calibrate climate proxy models by correlating ring-width indices with instrumental climate records.
• Analyze long-term growth trends and climate sensitivity of Douglas-fir (PSME) in Wyoming.
• Establish a dated chronology for cross-referencing with other paleoclimate archives from the region.

Strengths

• Time series spans 475 years, from 460 to -15 calendar years BP.
• Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• Dataset is temporally stale, with a last update date of 1965.
• Specific sample size, measurement parameters, and data formats are unknown from the description.
• Geographic coverage is limited to a single site in Wyoming.
