California Tree-Ring Width Chronology from 750 to -37 BP

750 to -37 calendar years before present of tree-ring width data from California, United States. The dataset is a paleoclimatology study from the NOAA National Centers for Environmental Information's World Data Service for Paleoclimatology. It was archived by NOAA NCEI and last updated in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree-ring width chronology.
• Calibrate climate proxy models using the dated annual resolution of the ring-width series.
• Study long-term ecological responses to climate by examining growth trends over the 787-year period.
• Compare this California chronology with other North American tree-ring records from the PAGES 2k network.

Strengths

• Covers a 787-year period from 750 to -37 calendar years BP.
• Provides annually-resolved proxy data for climate reconstruction.
• Archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, last updated in 1987.
• Geographic coverage is limited to two sites (Carson Pass East and Caples Lake) in California.
• Sample size, replication depth, and potential missing years within the chronology are unknown.
