Tree ring width measurements from Long Pine Creek, Nebraska, provide a climate proxy record. The chronology spans 265 years, from 218 to -47 calendar years before present. The data was archived by NOAA's National Centers for Environmental Information in 1997.
Use Cases
- Reconstruct historical temperature or precipitation anomalies using the tree ring width time series.
- Calibrate climate models by comparing the proxy record from this chronology with instrumental data.
- Analyze the frequency of drought events in Nebraska by identifying narrow ring sequences in the chronology.
- Study the growth response of Ponderosa Pine (PIPO) to past climatic stresses using the annual resolution data.
Strengths
- Covers a 265-year time period (218 to -47 BP), providing a multi-century climate record.
- Data is curated and archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -47 BP (47 BCE), lacking data for the most recent two millennia.
- Data is geographically limited to a single site (Long Pine Creek) in Nebraska.
- The dataset was last updated in 1997, indicating potential staleness in metadata or availability.
