476 to -15 calendar years before present (BP) of tree ring data from the Defiance West (Defiance/Nazlini) site in Arizona. This archived paleoclimatology study contains parameters related to tree ring growth and is available from the NOAA National Centers for Environmental Information (NCEI) World Data Service for Paleoclimatology. The data was archived by NOAA_NCEI, with a last recorded update in 1965.
Use Cases
- Reconstruct past climate variables like temperature or precipitation using annual tree ring width measurements.
- Analyze growth trends and anomalies in PSME (Ponderosa Pine) trees over a 491-year period.
- Calibrate tree ring chronologies for the Arizona region by cross-dating ring patterns.
- Study the response of tree growth to environmental events recorded in the ring sequence.
Strengths
- Covers a 491-year time period from 476 to -15 BP.
- Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
Limitations
- The dataset's last recorded update was in 1965, indicating potential staleness in metadata or documentation.
- Specific sample size (tree core count), measurement columns, and data formats are unknown.
