NOAA/WDS Paleoclimatology archives a tree ring chronology from Rata Creek, New Zealand. The data covers 193 years, from 163 to -30 calendar years before present. It was published by NOAA National Centers for Environmental Information.
Use Cases
- Reconstructing past temperature or precipitation anomalies using tree ring width measurements.
- Calibrating radiocarbon dating models for the New Zealand region with the dated chronology.
- Analyzing climate event frequency, such as droughts, from annual growth variations in the series.
Strengths
- Data spans a 193-year period (163 to -30 BP), providing a multi-century record.
- Sourced from the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- The dataset appears small, with an unspecified but likely limited number of core samples.
- Temporal coverage ends at -30 BP (approximately 1980 CE), lacking recent decades.
- Geographic scope is restricted to a single site (Rata Creek) in New Zealand.
