Mount Dana Tree Ring Chronology From Washington State

Tree ring width measurements from the Mount Dana site in Washington State provide a 140-year paleoclimate record from 100 to -40 calendar years before present. This chronology, part of the International Tree-Ring Data Bank (ITRDB), is archived by NOAA's World Data Service for Paleoclimatology. The dataset was last updated in the NOAA system in 1990.

Use Cases

• Reconstruct past temperature or precipitation anomalies by analyzing the tree_ring_width time series.
• Calibrate climate models using the precisely dated chronology spanning 140 calendar years BP.
• Study local environmental stress events by identifying narrow ring sequences in the growth series.
• Compare the ABLA (Abies lasiocarpa) species response at this site with other ITRDB chronologies.

Strengths

• Covers a 140-year time period (100 to -40 calendar years BP) from a single species and location.
• Archived and standardized by NOAA's authoritative World Data Service for Paleoclimatology.

Limitations

• Temporal coverage is relatively short (140 years) compared to millennial-length tree ring records.
• Data recency is low, with a last update recorded in 1990, potentially lacking modern reanalysis.
• Geographic scope is limited to a single site (Mount Dana) in Washington, USA.
