California Tree-Ring Width Chronology from 750 to 37 BC

750 to 37 BC tree-ring width data from a site in California, USA, provides a proxy record for past climate conditions. The dataset is part of the PAGES North America 2K paleoclimate reconstruction project and is archived by NOAA's World Data Service for Paleoclimatology. It was published in 1987.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree-ring width time-series.
• Calibrate climate models using the high-resolution proxy data from the Sardine Point site.
• Study long-term ecological resilience and growth patterns of the tree species (JUOC) represented in the chronology.
• Compare this California record with other PAGES 2K network chronologies to analyze regional climate patterns.

Strengths

• Covers a 713-year period (750 to 37 BC), providing a long-term baseline.
• Part of the standardized PAGES North America 2K network, ensuring methodological consistency for continental-scale analysis.
• Archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last update in 1987, potentially missing newer methodological refinements.
• Geographic coverage is limited to a single site (Sardine Point, California), limiting spatial representativeness.
• The raw sample size, replication, and measurement uncertainty for the tree-ring series are unknown from the provided metadata.
