Tree ring width measurements from Caribou Creek, Alaska, used for paleoclimate reconstruction. The chronology spans 437 years, from 391 to -46 calendar years before present. The dataset was archived by NOAA NCEI's World Data Service for Paleoclimatology and last updated in 1996.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
- Calibrate climate models by comparing the chronology with instrumental records for the overlapping period.
- Analyze growth response and climate sensitivity of the sampled tree species in Alaska.
- Establish a regional master chronology by cross-dating this series with other ITRDB records.
