191 calendar years of tree ring data from Mount Billy Mitchell, Alaska, spanning from 158 to -33 years before present. This paleoclimatology study was archived by NOAA's National Centers for Environmental Information and World Data Service for Paleoclimatology. The dataset was last updated in 1983.
Use Cases
- Reconstructing historical temperature or precipitation anomalies using the tree ring width chronology.
- Calibrating climate models by comparing the proxy tree ring data with instrumental climate records.
- Analyzing long-term ecological trends and forest response to past climate events in Alaska.
- Establishing a dated chronology for cross-referencing with other paleoclimate proxy records from the region.
