Nantack Gap Tree Ring Chronology For Paleoclimate Reconstruction

316-year tree ring chronology from 300 to -16 calendar years before present, providing proxy climate data. The dataset contains parameters of tree ring growth from a Pseudotsuga menziesii (PSME) site in Arizona, USA. It is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using annual tree ring width measurements.
• Analyze long-term growth trends and extreme events (e.g., droughts) from the ring width time series.
• Calibrate and validate climate models by comparing the proxy tree ring record with instrumental data.
• Study the response of Douglas fir (PSME) to environmental stressors over a multi-century timeframe.

Strengths

• 316-year continuous chronology providing a long-term paleoclimate record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -16 BP (1966 CE), with no updates since the original study publication.
• Geographic scope is limited to a single site (Nantack Gap, Arizona), limiting regional generalizability.
• Specific parameters, sample depth, and measurement methodologies are not detailed in the provided description.
