NOAA/WDS Paleoclimatology archives a tree-ring chronology from the Helen's Dome site in Arizona. The dataset provides a proxy climate record covering 297 years, from 260 to -37 calendar years before present. NOAA National Centers for Environmental Information compiled this data as part of its World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past temperature or precipitation using tree-ring width measurements as a proxy.
- Calibrate climate models by comparing the tree-ring chronology with instrumental records for the region.
- Analyze growth anomalies in the PIPO (Pinus ponderosa) series to identify extreme drought or wet periods.
- Establish a dated chronology for archaeological or geological studies in the Arizona region.
Strengths
- Covers a 297-year time series from 260 to -37 BP.
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -37 BP, providing no data for recent centuries.
- Geographic scope is limited to a single site (Helen's Dome) in Arizona.
- Data last updated in 1987, indicating potential methodological staleness.
