Boulder Shelter Pine Tree Ring Chronology from Washington State

Tree ring measurements from a Pseudotsuga menziesii (PSME) pine at Boulder Shelter in Washington State, USA. The chronology spans from 200 to -26 calendar years before present (BP), indicating coverage around 200 BCE to 26 CE. The data is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology.

Use Cases

• Reconstruct local precipitation or temperature anomalies using annual tree ring width measurements.
• Calibrate regional climate models by comparing the tree ring chronology with other proxy records.
• Analyze growth response to environmental events by examining variability in the ring width time-series.

Strengths

• Data spans approximately 226 calendar years, from 200 BCE to 26 CE.
• Associated with the NOAA NCEI Paleoclimatology archive, ensuring formal curation.

Limitations

• Data originates from a single tree (ITRDB WA031), limiting spatial representativeness.
• The last update recorded was in 1976, indicating potential staleness in metadata or methods.
