California Tree Ring Chronology from Clear Lake State Park (308 BC to AD 46)

Tree ring width measurements from Clear Lake State Park, California, covering the period from 308 BC to AD 46. The dataset is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. It was last updated in the public archive in 1996.

Use Cases

• Reconstruct annual precipitation or temperature anomalies for California using the tree ring width parameter.
• Calibrate the tree ring chronology against other proxy records for the 308 BC to AD 46 period to validate climate models.
• Analyze growth patterns and extreme climate events within the time-series data to identify historical droughts or wet periods.

Strengths

• Covers a 354-year period from 308 BC to AD 46, providing a multi-century climate record.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last known update in 1996, potentially missing methodological improvements.
• Geographic scope is limited to a single site (Clear Lake State Park, California), limiting regional representativeness.
• Specific sample depth, measurement statistics, and metadata details are not provided in the input.
