Alaskan Tree Ring Chronology From 250 to -45 BP

Tree ring data from Alaska provides a paleoclimate record covering 295 years, from 250 to -45 calendar years before present. The dataset was archived by NOAA's National Centers for Environmental Information under its World Data Service for Paleoclimatology. This study was last updated in January 1995.

Use Cases

• Reconstruct past climate variables like temperature or precipitation by analyzing tree ring width and density parameters.
• Calibrate and validate climate models using the 295-year chronology of environmental proxy data.
• Study ecological responses to historical climate events in Alaska through the tree ring record.

Strengths

• Covers a specific 295-year time period from 250 to -45 BP.
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, with a last recorded update in 1995.
• The sample size, geographic scope, and specific measured parameters are not detailed in the provided metadata.
