California Tree Ring Chronology from 508 to 42 BCE

508 to 42 BCE tree ring data from the McKinley Grove site in California, United States. The dataset is part of the NOAA/WDS Paleoclimatology archive and was contributed by Hughes. It was last updated in 1992.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using tree ring width measurements.
• Calibrate and validate climate models with a proxy record spanning over 500 years.
• Analyze long-term ecological trends and forest growth responses in California's Sierra Nevada region.
• Study the frequency and impact of historical drought events recorded in the tree ring series.

Strengths

• Covers a 550-year time period from 508 to 42 BCE.
• Sourced from the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Data is temporally stale, with a last update recorded in 1992.
• Specific sample size, measurement parameters, and file formats are not provided in the metadata.
