Nancy Brook Tree Ring Chronology for New Hampshire Paleoclimate

A 411-year tree-ring chronology from the Nancy Brook site in New Hampshire, USA, covering the period from 389 to -22 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. This tree-ring study was last updated in the NOAA system in 1972.

Use Cases

• Reconstruct past temperature or precipitation anomalies using annual tree-ring width measurements.
• Calibrate climate models by comparing the tree-ring proxy record with instrumental data for the region.
• Analyze long-term ecological growth patterns and responses to environmental stressors in New Hampshire forests.
• Establish cross-dating references for other tree-ring collections from the northeastern North America.

Strengths

• Covers a 411-year period, providing a multi-century climate proxy.
• Geographically specific to a single site in New Hampshire, allowing for localized analysis.
• Archived and curated by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The data's last recorded update was in 1972, indicating potential staleness and lack of recent curation.
• The sample size (number of tree cores or series) is unknown, which limits assessment of statistical robustness.
• Coverage ends at -22 years BP (1972 CE), preventing analysis of recent climate change impacts.
