Tree-ring fire scar data from Sawmill Canyon in Arizona, used to reconstruct historical fire events. The record spans 496 calendar years, from 451 to -45 years before present. The dataset was archived by NOAA's World Data Service for Paleoclimatology and last updated in 1995.
Use Cases
- Analyze fire return intervals using fire scar dates and tree-ring calendar years.
- Reconstruct historical fire frequency and seasonality from recorded fire scar parameters.
- Correlate fire event years with regional climate proxy records to study climate drivers.
- Map the spatial extent of past fires using the geographic location data for Arizona.
Strengths
- Covers a 496-year time period (451 to -45 BP).
- Provides a specific geographic location (Sawmill Canyon, Arizona).
Limitations
- Data is temporally stale, last updated in 1995.
- Sample size and specific parameter counts are unknown.
- Geographic scope is limited to a single canyon in Arizona.
