Tree ring width measurements from the Takapari site in New Zealand, used for climate reconstruction. The data covers a 736-year period from 694 to -42 calendar years before present. It is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1992.
Use Cases
- Reconstruct past temperature or precipitation anomalies from tree ring width chronologies.
- Calibrate regional climate models by comparing the tree ring proxy record with instrumental data.
- Analyze long-term climate trends in New Zealand over a 736-year period.
- Study the response of specific tree species to historical climate events recorded in ring widths.
Strengths
- Covers a 736-year time period (694 to -42 BP)
- Part of the authoritative NOAA/NCEI Paleoclimatology archive
Limitations
- Data is from a single site (Takapari), limiting spatial representativeness
- Last update was in 1992, potentially lacking modern methodological refinements
