Tree-ring width measurements from the Little Juniper Mountain site in Oregon, United States. The chronology covers 480 years, from 450 to -30 calendar years before present. Data is archived by NOAA's World Data Service for Paleoclimatology and was last updated in 1980.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series.
- Calibrate climate models by comparing the tree-ring width chronology with simulated climate data over the 480-year period.
- Analyze growth trends and extreme events (e.g., droughts) recorded in the ring width data.
- Study regional climate synchrony by comparing the JUOC site chronology with other North American tree-ring records.
Strengths
- Chronology spans 480 calendar years, providing a multi-century climate record.
- Data is curated and archived by NOAA's authoritative World Data Service for Paleoclimatology.
Limitations
- Temporal coverage ends at -30 BP (approximately 1980 CE), lacking recent decades.
- Data is from a single site (JUOC), limiting spatial representativeness for broader regional analysis.
- The last update recorded was in 1980, indicating the dataset is not actively maintained.
