Oregon Tree Ring Chronology from 531 to -45 BP

Tree ring width measurements from a ponderosa pine (PIPO) site at the junction of Highways 51 and 97 in Oregon, USA. The chronology spans 576 years, from 531 to -45 calendar years before present, and was archived by NOAA NCEI's World Data Service for Paleoclimatology. The data was last updated in the NOAA archive in 1995.

Use Cases

• Reconstruct past temperature or precipitation anomalies by calibrating tree ring width measurements against instrumental climate records.
• Analyze growth patterns and climate sensitivity of ponderosa pine (PIPO) in a specific Oregon location.
• Establish a dated tree ring chronology for cross-dating with other regional paleoclimate proxies.
• Study long-term environmental changes over a 576-year period in calendar years before present (BP).

Strengths

• Chronology covers a substantial 576-year time period (531 to -45 BP).
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.
• Provides a geographically specific record for a site in Oregon, USA.

Limitations

• Data is temporally stale, with a last archive update noted as 1995.
• The sample size (number of tree cores or series) is unknown, limiting assessment of statistical robustness.
• Geographic coverage is limited to a single tree ring site.
