Tree-ring fire-scar data from Mount Lemmon, Arizona, spans 559 years from 514 to -45 calendar years before present. The dataset documents fire history parameters for paleoclimatic research. It was archived by NOAA's National Centers for Environmental Information and last updated in 1995.
Use Cases
- Reconstructing historical fire frequency and seasonality using fire-scar dates from tree rings.
- Analyzing climate-fire relationships by correlating fire event years with tree-ring width chronologies.
- Modeling long-term fire return intervals for the Santa Catalina Mountains based on the dated fire events.
Strengths
- Covers a 559-year time period from 514 to -45 calendar years BP.
- Provides a direct physical proxy (tree-ring fire scars) for historical fire events.
Limitations
- Data is temporally stale, with a last recorded update in 1995.
- Geographic scope is limited to a single mountain range in Arizona.
