NOAA's Paleoclimatology archive provides a tree-ring width chronology from the Big Quilcene River Trail in Washington, USA. The data covers a 480-year period from 450 to -30 calendar years before present. This study was contributed by Earle and is part of the PAGES North America 2K initiative, archived by the NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct annual climate variables like temperature or precipitation using the tree-ring width time-series as a proxy.
- Analyze growth anomalies in the PSME (Pseudotsuga menziesii) species record to identify past environmental stress events.
- Calibrate and validate the tree-ring chronology against the PAGES North America 2K network for regional climate synthesis.
- Study decadal to centennial-scale climate trends in the Pacific Northwest from 450 to -30 BP using the dated width series.
Strengths
- Time-series covers a 480-year period from 450 to -30 calendar years BP.
- Data is part of the authoritative PAGES North America 2K paleoclimate reconstruction network.
Limitations
- Dataset appears to have a last update date of 1980, indicating it is a static, legacy archive.
- Specific sample depth, replication statistics, and measurement precision are unknown from the provided description.
