Mount Katahdin Tree Ring Chronology From 340 BC

371 years of tree ring data from the Hamlin Ridge site on Mount Katahdin in Maine, USA, covering the period from 340 to -31 calendar years before present. The dataset is part of the NOAA NCEI World Data Service for Paleoclimatology, archived as a Tree Ring study. It was last updated in the NOAA system in 1981.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using the tree ring width chronology.
• Calibrate radiocarbon dating or other chronological models by cross-referencing the established tree ring timeline.
• Analyze long-term ecological growth patterns and disturbance events recorded in the ring data from this specific site.

Strengths

• Chronology spans 371 calendar years, providing a multi-century climate proxy.
• Data is archived and curated by the authoritative NOAA National Centers for Environmental Information.

Limitations

• The dataset has not been updated in the source system since 1981, potentially missing modern reanalysis.
• Geographic coverage is limited to a single site (Hamlin Ridge, Mount Katahdin), limiting regional generalizations.
• Specific measured parameters (e.g., ring width, density) and sample depth are not detailed in the provided metadata.
