Tree ring width measurements from a ponderosa pine (PSME) site in the Galiuro Mountains of Arizona, used for paleoclimate reconstruction. The chronology covers the period from 300 to 15 calendar years before present. Data is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology.
Use Cases
- Reconstruct past temperature or precipitation anomalies using the tree-ring width time-series.
- Calibrate the chronology against other proxy records from the southwestern US region.
- Analyze growth patterns for evidence of historical drought events in Arizona.
- Validate climate model simulations of the past 300 years using the dated proxy record.
Strengths
- Time-series data spans 315 years (300 to 15 BP), providing a multi-century record.
- Data is curated and archived by NOAA NCEI, an authoritative source for paleoclimate data.
Limitations
- Data is from a single tree species at one site, limiting spatial representativeness.
- The dataset's last update was in 1965, indicating potential staleness in metadata or methods.
- Sample size (number of tree cores) and replication statistics are unknown.
