Cathedral Peak Tree Ring Chronology For Paleoclimate Analysis

70 calendar years of tree ring width data from Cathedral Peak in Yosemite National Park, California. The dataset was archived by NOAA's National Centers for Environmental Information under its Paleoclimatology program. It was last updated in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
• Calibrate climate models by comparing the chronology data against instrumental records for the California region.
• Analyze growth response patterns to infer historical drought events from the ring width measurements.

Strengths

• Data covers a 70-year time period for climate analysis.
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is limited to 70 calendar years before present.
• Data is geographically specific to a single site in California.
• The dataset has not been updated since 1990, potentially lacking modern methodological refinements.
