490 to -36 calendar years BP of tree ring width measurements from Ponderosa Pine trees in Arizona, USA. This paleoclimatology dataset was archived by NOAA's National Centers for Environmental Information (NCEI) under the World Data Service for Paleoclimatology. The study was last updated in 1986.
Use Cases
- Reconstruct past climate variables like temperature or precipitation by analyzing the tree ring width time-series.
- Calibrate radiocarbon dating or other dating methods using the established tree ring chronology.
- Study long-term ecological responses, such as growth patterns, to environmental changes recorded in the ring data.
Strengths
- Time-series covers 526 calendar years (from 490 to -36 BP)
- Data is curated and archived by the authoritative NOAA/NCEI World Data Service for Paleoclimatology
Limitations
- Temporal coverage ends at -36 BP (36 years before 1950), lacking recent decades
- Dataset last updated in 1986, indicating potential staleness in metadata or availability
