Saddle Mountain Road Tree Ring Chronology from Arizona

257 calendar years of tree ring data from a Pseudotsuga menziesii (PSME) site in Arizona, USA, covering the period from 257 to -25 years before present. This paleoclimatology study is archived by the NOAA National Centers for Environmental Information under the World Data Service for Paleoclimatology. The data was last updated in the NOAA system in 1975.

Use Cases

• Reconstructing past climate conditions like temperature or precipitation using annual tree ring width measurements.
• Calibrating radiocarbon dating or other chronological models with the dated tree ring series.
• Analyzing long-term ecological responses, such as growth trends in Pseudotsuga menziesii, to environmental changes.
• Comparing this local tree ring chronology (ITRDB AZ505) with regional datasets to identify broader climate signals.

Strengths

• Covers a 257-year time series, providing a multi-century environmental record.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at -25 BP (approximately 1975 CE), making the record potentially stale for modern analysis.
• The single-site geographic focus (Saddle Mountain Road, Arizona) limits generalizability.
• Lack of accessible sample data or column details hinders immediate assessment of data structure and variables.
