Tree Ring Chronology For White Pass Washington From 65 To -36 BP

NOAA/WDS Paleoclimatology archives a tree ring chronology from the Rimrock Valles Ground White Pass site in Washington, USA. The dataset provides a time series covering the period from 65 to -36 calendar years before present. NOAA National Centers for Environmental Information (NCEI) compiled and maintains this paleoclimate record.

Use Cases

• Reconstruct past temperature or precipitation anomalies using the tree ring width chronology.
• Calibrate climate models by comparing the chronology data with instrumental records for the overlapping period.
• Analyze growth patterns in Pseudotsuga menziesii (PSME) trees from the ITRDB WA4 site for ecological studies.
• Establish a dated timeline for environmental events using the calendar years before present (BP) coverage.

Strengths

• Time series coverage spans 101 calendar years (from 65 to -36 BP).
• Data is archived and curated by the authoritative NOAA National Centers for Environmental Information (NCEI).

Limitations

• Temporal coverage is limited to a specific 101-year window, which is short for some long-term climate trend analyses.
• The dataset's last documented update was in 1986, indicating it is a static historical archive with no recent revisions.
• Geographic scope is restricted to a single site (White Pass, Washington), limiting broad regional conclusions.
