Tree-ring width data from Washington state, USA, spans 463 calendar years before present (BP) to 30 BP. The dataset is part of the NOAA/WDS Paleoclimatology archive, contributed by researcher Graumlich and archived by NOAA NCEI. Data was last updated in the system in 1980.
Use Cases
- Reconstruct past climate variables like temperature or precipitation using the tree-ring width time-series.
- Calibrate the tree-ring chronology against known historical climate events within its 463-year span.
- Analyze growth patterns in the 'LAOC' species (likely Larix occidentalis) for ecological studies.
- Compare this 'ITRDB WA052' site chronology with other regional tree-ring records to assess spatial climate patterns.
Strengths
- Covers a specific 463-year period in the past, providing a multi-century climate proxy.
- Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection within NOAA's World Data Service.
Limitations
- Temporal coverage ends at 30 BP, making the most recent data over 2000 years old.
- The dataset's last known update was in 1980, potentially lacking modern re-calibration or metadata enhancements.
- Specific sample depth, replication statistics, and measurement precision are unknown from the provided description.
