Grand Canyon Tree Ring Chronology from 193 to 45 BC

Arizona's Lower Walhalla Plateau provides a tree ring chronology for paleoclimate reconstruction. The dataset contains tree ring parameters from the North Rim of Grand Canyon National Park, specifically for Ponderosa Pine (PIPO). NOAA National Centers for Environmental Information archived this study, which was last updated in 1995.

Use Cases

• Reconstruct past climate variables like precipitation or temperature from tree ring width measurements.
• Calibrate radiocarbon dating models using the provided calendar years before present (BP) time series.
• Analyze growth patterns of Ponderosa Pine (PIPO) in response to historical environmental stressors.
• Compare this ITRDB AZ562 site chronology with other regional tree ring datasets for spatial climate analysis.

Strengths

• Time series covers 238 years, from 193 to 45 calendar years before present.
• Data is curated and archived by the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Temporal coverage ends at 45 BP, providing no data for the modern Common Era period.
• Dataset metadata and specific parameters are not detailed in the provided description, requiring further investigation.
• The last recorded update was in 1995, indicating the data collection and processing methods may be outdated.
