California Tree Ring Chronology from 773 to -38 BP

Tree ring width data from the Yolla Bolly region of California provides a climate proxy record spanning 811 years. The dataset, archived by NOAA's World Data Service for Paleoclimatology, was contributed by researcher Buckley and last updated in 1988. It is part of the International Tree-Ring Data Bank (ITRDB) collection.

Use Cases

• Reconstruct annual temperature or precipitation anomalies from tree ring width measurements.
• Calibrate climate models by comparing the tree ring chronology against instrumental records for the region.
• Identify extreme climate events, such as multi-year droughts, within the 811-year time series.
• Analyze growth trends and potential ecological shifts over the centuries before present.

Strengths

• 811-year continuous chronology from 773 to -38 BP.
• Data is part of the authoritative International Tree-Ring Data Bank (ITRDB).

Limitations

• Data has not been updated since 1988, potentially missing modern verification or recalibration.
• Specific sample depth, measurement parameters, and site details are not provided in the basic description.
