NOAA/WDS Paleoclimatology archives a tree ring chronology for Boulder Creek, Washington, created by Ferguson. The dataset covers a time period from 430 to -15 calendar years before present, measured from the Douglas-fir species (PSME). This study is part of the International Tree-Ring Data Bank (ITRDB) and is maintained by NOAA National Centers for Environmental Information.
Use Cases
- Reconstruct annual temperature or precipitation anomalies from tree ring width measurements.
- Calibrate climate models using the 445-year chronology as a proxy record.
- Analyze growth patterns in Douglas-fir (PSME) to study historical ecological stress events.
- Compare this ITRDB WA042 chronology with other regional series to assess spatial climate signals.
Strengths
- Time series spans 445 years, from 430 to -15 BP.
- Data is part of the curated International Tree-Ring Data Bank (ITRDB).
Limitations
- Data was last updated in 1965, making it a historical archive with potentially outdated methods.
- The geographic coverage is limited to a single site (Boulder Creek, Washington).
- Specific measurement parameters and sample depths are unknown from the provided description.
