NOAA/WDS Paleoclimatology archives a tree ring dataset from the Summit Lode Road site in Washington. The chronology covers 555 years, from 530 to -25 calendar years before present. NOAA National Centers for Environmental Information (NCEI) maintains this record, last updated in 1975.
Use Cases
- Reconstruct past temperature or precipitation anomalies using annual tree ring width measurements.
- Calibrate climate models by comparing the chronology with other proxy records from the region.
- Analyze growth trends and extreme events (e.g., droughts) encoded in the ring width time series.
- Study the response of Pseudotsuga menziesii (PSME) to historical climate forcing over a 555-year period.
Strengths
- Chronology spans 555 years, providing a multi-century climate record.
- Data is curated and archived by the authoritative NOAA NCEI World Data Service.
Limitations
- Temporal coverage ends at -25 BP (1975 CE), lacking recent decades.
- Data is from a single site (Summit Lode Road), limiting spatial representativeness.
- Specific measurement parameters and sample depth are not provided in the input.
