Yosemite Tree Ring Chronology from 70 to -41 BP

Tree ring width measurements from the Gin Flat site in Yosemite National Park, California, covering a 111-year period from 70 to -41 calendar years before present. This paleoclimatology dataset was archived by the NOAA National Centers for Environmental Information and last updated in 1991.

Use Cases

• Reconstruct past climate conditions like temperature or precipitation using annual tree ring width variations.
• Calibrate radiocarbon dating or other chronological methods using the established tree ring chronology.
• Analyze forest growth responses to specific historical events within the 111-year time window.
• Compare this site's growth patterns with other tree ring chronologies from the western United States.

Strengths

• Covers a specific 111-year time period (70 to -41 BP) for clear temporal analysis.
• Data is curated and archived by the authoritative NOAA National Centers for Environmental Information.

Limitations

• Data is temporally stale, with a last update recorded in 1991.
• The sample size (number of trees or cores) is unknown, limiting statistical confidence.
• Geographic coverage is limited to a single site in Yosemite National Park.
