California Tree-Ring Width Chronology from Dalton Reservoir

480 calendar years of tree-ring width data from a Pinus ponderosa site at Dalton Reservoir, California. The dataset is archived by NOAA's World Data Service for Paleoclimatology and represents a Tree Ring study type. The temporal coverage spans from 450 to -30 calendar years before present.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree-ring width time-series.
• Calibrate the chronology against known historical events using the calendar years before present (BP) time axis.
• Compare climate proxy signals from this Pinus ponderosa (PIPO) site with other regional tree-ring records.
• Study long-term forest growth responses to climate by examining the width parameter over a 480-year period.

Strengths

• 480-year temporal coverage from 450 to -30 calendar years BP.
• Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Dataset appears temporally stale, with a last updated date of 1980.
• Geographic coverage is limited to a single site (CA065) in California.
• Sample size (number of tree cores) and replication statistics are unknown.
