Alaskan Tree Ring Chronology for Paleoclimate Reconstruction

Tree ring width measurements from the Russelfjord Southern End A site in Alaska, used for paleoclimate studies. The chronology covers 158 years, from 122 to -36 calendar years before present. Data is archived by NOAA National Centers for Environmental Information (NCEI) and was last updated in 1986.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width time-series.
• Calibrate climate models by comparing the tree ring chronology with instrumental records for the region.
• Analyze growth response and climate sensitivity of trees at the Alaskan site over the 158-year period.
• Establish a regional dendrochronological master chronology using the site-specific ring width data.

Strengths

• Data spans a continuous 158-year period (122 to -36 BP).
• Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.

Limitations

• The dataset is temporally stale, with a last update date of 1986.
• Limited geographic scope to a single site (Russelfjord Southern End A) in Alaska.
• The specific sample size (number of tree cores) and measurement parameters are not provided in the input.
