352 to -21 calendar years before present of tree ring width measurements from ponderosa pine (PSME) in Spider Rock Canyon, Canyon de Chelly, Arizona. This paleoclimatology dataset was 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 1971.
Use Cases
- Reconstruct past climate variables like precipitation or temperature by analyzing annual tree_ring_width variations over the 373-year chronology.
- Calibrate and validate climate models for the southwestern US using the dated proxy record from the Arizona location.
- Study long-term ecological responses to climate change by examining growth trends in the PSME (Pinus ponderosa) species data.
- Perform cross-dating analysis to extend or validate other regional tree ring chronologies using this ITRDB AZ080 series.
Strengths
- Covers a 373-year time period from 352 to -21 calendar years BP.
- Provides a dated, site-specific proxy record for a key paleoclimate region in Arizona.
Limitations
- Temporal coverage ends 21 years before present (1950 CE standard), limiting analysis of the most recent climate period.
- Sample size and replication statistics for the tree ring series are unknown from the provided metadata.
- Data was last updated in the archival system in 1971, potentially indicating older collection methods.
