Pennsylvania Tree Ring Chronology from 341 to 31 BC

341 to 31 BC tree ring data from Dingman's Falls State Park in Pennsylvania, United States. This paleoclimatology study contains parameters for dendrochronological analysis and is archived by NOAA's World Data Service for Paleoclimatology. The dataset was published by NOAA NCEI and last updated in 1981.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate climate models by comparing the tree ring proxy data with instrumental records for the region.
• Analyze growth patterns and environmental stressors from the measured tree ring parameters.
• Establish a dated chronology for archaeological or geological studies in Pennsylvania using the annual resolution data.

Strengths

• Covers a 372-year period from 341 to 31 BC, providing a multi-century climate proxy.
• Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update date of 1981, potentially lacking modern reanalysis.
• Specific sample size, measured parameters, and data formats are not detailed in the provided metadata.
• Geographic coverage is limited to a single site in Pennsylvania, reducing regional generalizability.
