Alaskan Tree Ring Chronology for Paleoclimate Reconstruction

Tree ring width measurements from the Russelfjord Southern End D site in Alaska, used for paleoclimate studies. The chronology covers a 63-year period from 27 to -36 calendar years before present. The dataset was produced by Kaiser and archived by NOAA National Centers for Environmental Information, with a last update recorded in 1986.

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 from the Alaska region.
• Analyze growth trends and extreme events captured in the ring width data to infer past environmental stress.

Strengths

• Data originates from the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a specific 63-year chronology for a defined geographic location in Alaska.

Limitations

• The dataset is temporally stale, with a last update date of 1986.
• The sample size and specific measurement parameters are not detailed in the provided metadata.
• Geographic coverage is limited to a single site in Alaska.
