Tree ring width measurements from Tsuga mertensiana (TSME) trees near Mount Adams, Washington, provide a 272-year chronology. The dataset, archived by NOAA's World Data Service for Paleoclimatology, offers proxy climate data for the Pacific Northwest region. This record was published by the NOAA National Centers for Environmental Information in 1993.
Use Cases
- Reconstruct past temperature or precipitation anomalies by analyzing the tree_ring_width time series.
- Calibrate the tree_ring_width chronology against other regional paleoclimate proxies.
- Study the growth response of Tsuga mertensiana to volcanic activity from Mount Adams using the dated ring series.
- Validate climate model simulations for the late Holocene period using the dated proxy record.
Strengths
- Covers a continuous 272-year period from 229 to -43 calendar years before present.
- Sourced from the authoritative NOAA/NCEI World Data Service for Paleoclimatology.
Limitations
- Data is temporally stale, with a last update recorded in 1993.
- Geographic coverage is limited to a single site (Mount Adams, Washington).
- The sample size (number of tree cores) is unknown, which affects confidence in the chronology.
