NOAA/WDS Paleoclimatology archives a tree ring chronology from the Pillars site in Sequoia National Park, California. The data covers a period from 70 to -40 calendar years before present, representing growth patterns of White Fir (ABCO). This dataset is maintained by NOAA's National Centers for Environmental Information and was last updated in 1990.
Use Cases
- Reconstruct historical climate variables like temperature or precipitation from tree ring width measurements.
- Calibrate radiocarbon dating or other dating methods using the established tree ring chronology.
- Analyze growth anomalies in the White Fir (ABCO) ring series to identify past environmental stressors.
- Compare this site's chronology (ITRDB CA587) with other regional tree ring datasets for spatial climate analysis.
Strengths
- Data is archived by the authoritative NOAA World Data Service for Paleoclimatology.
- Covers a specific 110-year period (70 to -40 BP) with annual resolution typical of tree rings.
Limitations
- Temporal coverage is relatively short for paleoclimate studies at 110 years.
- Data is geographically limited to a single site (Pillars) within Sequoia National Park.
- The last update was in 1990, indicating the record has not been recently extended or revised.
