California Tree-Ring Width Chronology from 750 BC

Tree-ring width measurements from California provide a proxy climate record spanning 787 years, from 750 to 37 BC. The dataset is archived by NOAA's National Centers for Environmental Information under their Paleoclimatology program. Data was published in 1987.

Use Cases

• Reconstruct past temperature or precipitation in California using the tree-ring width time-series.
• Calibrate climate models by comparing the 787-year proxy record from this chronology with simulated past climates.
• Analyze long-term climate trends and variability for the period 750-37 BC using the annual-resolution data.
• Correlate this California tree-ring chronology with other regional paleoclimate proxies to study spatial climate patterns.

Strengths

• Provides a continuous 787-year annual-resolution climate proxy record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update date of 1987, potentially missing newer methodological refinements.
• Geographic coverage is limited to a single, unspecified location in California.
• The raw data format and specific measurement parameters are not detailed in the provided description.
