188 calendar years of tree ring data from Alaska, covering the period from 155 to -33 years before present. The dataset is archived by NOAA's World Data Service for Paleoclimatology as a Tree Ring study. The data was last updated in the NOAA system in 1983.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
- Calibrate the chronology against other proxy records for the 155 to -33 BP period.
- Analyze growth trends and extreme events captured in the ring parameters for Alaskan forests.
Strengths
- Covers a specific 188-year period (155 to -33 BP) for climate analysis.
- Archived by the authoritative NOAA World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with a last system update recorded in 1983.
- Limited geographic scope to a single location in Alaska.
