Tree Ring Chronology From Yosemite National Park 70 To -40 BP

NOAA's Paleoclimatology archive provides a tree-ring chronology from Gin Flat in Yosemite National Park, California. The data covers a 110-year period from 70 to -40 calendar years before present. This record was archived by the NOAA National Centers for Environmental Information in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree-ring width chronology.
• Calibrate radiocarbon dates or validate other paleoclimate proxies for the period 70 to -40 BP.
• Analyze growth response patterns to historical environmental events recorded in the ring sequences.
• Compare this chronology with other ITRDB series (e.g., ITRDB CA575) for regional climate signal analysis.

Strengths

• Data originates from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
• Covers a specific 110-year time period (70 to -40 BP) with clear temporal bounds.
• Associated with a known study type (Tree Ring) and a precise geographic location (Gin Flat, Yosemite).

Limitations

• The dataset's last known update was in 1990, indicating potential staleness and lack of recent curation.
• Specific data parameters, sample size (row count), and measurement details are not provided in the description.
• Geographic coverage is limited to a single site in California, restricting broader spatial analysis.
