Tree ring chronology data from Crystal Cave in Sequoia National Park, California. The dataset covers the period from 71 to -40 calendar years before present. It is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1990.
Use Cases
- Reconstruct past climate variables like temperature or precipitation using tree ring width series.
- Calibrate radiocarbon dates by aligning the tree ring chronology with known time periods.
- Analyze growth responses of Ponderosa Pine (PIPO) to environmental changes over a 111-year span.
- Compare this local chronology with other ITRDB (International Tree-Ring Data Bank) records for regional climate analysis.
Strengths
- Covers a specific 111-year time period (71 to -40 BP).
- Part of the authoritative NOAA/NCEI Paleoclimatology archive and ITRDB.
Limitations
- Data recency is low, last updated in 1990.
- Specific sample size, measurement methods, and column details are unknown.
