Tree ring width measurements from ponderosa pine (PIPO) at the Telephone Draw site in Oregon, United States. The chronology covers 425 years, from 380 to -45 calendar years before present, archived by NOAA's World Data Service for Paleoclimatology. Data was published by the NOAA National Centers for Environmental Information in 1995.
Use Cases
- Reconstruct past temperature or precipitation using the tree ring width parameter as a climate proxy.
- Calibrate the chronology against other regional tree ring records using the site's geographic location in Oregon.
- Analyze long-term growth trends and climate sensitivity in ponderosa pine (PIPO) over the 425-year time period.
- Study environmental changes during the period covered, from 380 to -45 BP, using the dated tree ring series.
Strengths
- Covers a 425-year time period (380 to -45 BP) providing multi-century climate context.
- Sourced from NOAA's authoritative World Data Service for Paleoclimatology, ensuring standardized metadata.
- Focuses on a single species (Ponderosa Pine) and site (Telephone Draw), reducing interspecies and geographic noise.
Limitations
- Data is temporally stale, last updated in 1995 and may not reflect current methodological standards.
- Limited geographic scope to a single site in Oregon, reducing broad regional representativeness.
- Unknown sample depth (number of tree cores) and replication, which affects chronology signal strength.
