110-year tree-ring chronology from 70 to -40 calendar years before present, derived from Ponderosa Pine (Pinus ponderosa) samples at Oak Flat Road in Yosemite National Park, California. The dataset is archived by the NOAA National Centers for Environmental Information under its World Data Service for Paleoclimatology. The data was last updated in the NOAA system in 1990.
Use Cases
- Reconstruct past climate conditions like temperature or precipitation by analyzing the tree-ring width series.
- Calibrate radiocarbon dating or other chronological models using the provided calendar year BP timeline.
- Study the growth response of Pinus ponderosa (PIPO) to environmental changes over a 110-year period.
- Compare this site chronology (ITRDB CA583) with other tree-ring datasets for regional climate signal analysis.
Strengths
- Data covers a 110-year time period (70 to -40 BP) for climate analysis.
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
- Precise geographic location specified for Yosemite National Park, California.
Limitations
- Temporal coverage is relatively short (110 years) for long-term climate trend analysis.
- Data last updated in 1990, potentially lacking modern reanalysis or corrections.
- Sample size, replication, and measurement specifics are unknown from the description.
