440 years of tree ring data from a Pinus ponderosa (PIPO) site in Oregon, United States, for paleoclimate reconstruction. The dataset is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. It was last updated in the NOAA system in 1990.
Use Cases
- Reconstruct past temperature or precipitation anomalies using annual tree ring width measurements.
- Calibrate the tree ring chronology against known climate events within the 440-year period.
- Analyze growth patterns in Pinus ponderosa (PIPO) from a specific Oregon location for ecological studies.
- Compare this ITRDB series (OR032) with other regional chronologies to assess spatial climate signals.
Strengths
- Covers a 440-year time period from 400 to -40 calendar years before present.
- Part of the authoritative International Tree-Ring Data Bank (ITRDB) collection curated by NOAA NCEI.
- Includes precise geographic location data for the sampling site in Oregon, USA.
Limitations
- The data record ends at -40 BP (approximately 1990 AD), lacking recent decades.
- Sample size and replication statistics for the tree ring series are unknown.
- Limited to a single tree species (Pinus ponderosa) at one location, reducing regional representativeness.
