St. John Mountain Tree Ring Chronology For Climate Reconstruction

450 calendar years of tree ring data from the St. John Mountain site in California, used for paleoclimate studies. The dataset was archived by NOAA's World Data Service for Paleoclimatology and is associated with their Tree Ring study type. This record was last updated in 1980.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing annual tree ring width measurements.
• Calibrate climate models using the 450-year chronology of environmental proxies from Pinus ponderosa (PIPO).
• Study the response of Pinus ponderosa growth to climatic events within the ITRDB CA082 site chronology.

Strengths

• Covers a 450-year time series from 450 to -30 calendar years BP.
• Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The temporal coverage ends at -30 BP, making it less recent for modern climate comparisons.
• The dataset's last update was in 1980, potentially indicating outdated metadata or documentation.
• Specific sample size, measurement parameters, and data formats are not provided in the description.
