426 to -40 calendar years before present (BP) of tree ring data from Alaska, United States. This paleoclimatology dataset is archived by the NOAA National Centers for Environmental Information (NCEI) World Data Service. The data was last updated in 1990.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
- Calibrate climate models by comparing the tree ring proxy data with instrumental records for the overlapping period.
- Analyze the frequency of extreme climate events, such as droughts or cold periods, indicated by narrow rings in the chronology.
- Study ecological responses to historical climate shifts by examining growth patterns in the tree ring series.
Strengths
- Covers a significant time span of 466 years (426 to -40 BP).
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Data recency is low, with a last update recorded in 1990.
