Tree ring width data from Denali National Park, Alaska, provides a 429-year paleoclimate record. The chronology covers the period from 396 to 33 calendar years before present. This archived study was published by NOAA's World Data Service for Paleoclimatology in 1983.
Use Cases
- Reconstruct past temperature anomalies using tree ring width as a proxy.
- Calibrate radiocarbon dating models by cross-referencing this dendrochronological series.
- Analyze growth response to volcanic events or climatic extremes within the 429-year record.
- Compare this Alaskan tree ring chronology with other regional series to identify broad climate patterns.
Strengths
- 429-year continuous chronology from 396 to 33 BC.
- Data originates from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends over 2000 years ago, limiting analysis of recent climate change.
- Single geographic location (Denali National Park) limits spatial representativeness for Alaska.
- Data publication date is 1983, potentially missing modern methodological refinements.
