Sequoia National Park Tree Ring Chronology 70 to -40 BP

70 to -40 calendar years before present (BP) of tree ring data from Crescent Meadow in Sequoia National Park, California. The dataset contains parameters related to tree ring growth, archived by the NOAA National Centers for Environmental Information (NCEI) World Data Service for Paleoclimatology. The data was last updated in the repository in 1990.

Use Cases

• Reconstruct past climate variables like temperature or precipitation using tree ring width parameters.
• Calibrate and validate climate models for the Sierra Nevada region with the 110-year chronology.
• Analyze growth anomalies in the PIJE (Pinus jeffreyi) species record for specific years before present.
• Compare this chronology with other ITRDB (International Tree-Ring Data Bank) series for regional climate signal analysis.

Strengths

• Covers a 110-year chronology from 70 to -40 BP.
• Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The temporal coverage is relatively short for many paleoclimate studies.
• Data is geographically limited to a single meadow in Sequoia National Park.
• The dataset was last updated in 1990, indicating potential staleness in metadata or availability.
