Yosemite Tree Ring Chronology From 71 To -40 BP

Tree ring data from Hodgdon Yosemite National Park, covering the period from 71 to -40 calendar years before present. The dataset is archived by the NOAA National Centers for Environmental Information under its Paleoclimatology World Data Service. The record was last updated in 1990.

Use Cases

• Reconstruct past climate variables like temperature or precipitation from the tree-ring width parameter.
• Calibrate climate models by comparing the tree-ring chronology time series with other proxy records.
• Analyze growth anomalies in the ring data to identify extreme historical events such as droughts or fires.
• Establish a dated chronology for archaeological or geological studies in the Yosemite region using the BP timeline.

Strengths

• Time series coverage spans 111 years from 71 to -40 BP.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset's last update was in 1990, indicating potential staleness and lack of recent maintenance.
• Specific sample size, measurement methods, and column details are unknown from the provided metadata.
