California's Yosemite National Park provides the location for this tree ring chronology dataset. The data covers a period from 70 to -40 calendar years before present, representing a 110-year span. It is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology program.
Use Cases
- Reconstruct past climate variables like temperature or precipitation by analyzing the tree ring width series.
- Calibrate radiocarbon dating or other chronological methods using the established tree ring time series.
- Study ecological responses to historical events by examining growth anomalies within the ring record.
- Compare this local chronology with other regional tree ring datasets to identify broader climate patterns.
Strengths
- Data spans a 110-year period from 70 to -40 calendar years BP.
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Temporal coverage is relatively short for dendrochronological studies at 110 years.
- Geographic scope is limited to a single site (Hodgdon) within Yosemite National Park.
- Data record appears stale, with a last updated metadata date of 1990-01-01.
