Tree-ring data from Colorado reconstructs fire history over a 568-year period, from 521 to -47 calendar years before present. The dataset is archived by NOAA's National Centers for Environmental Information under the World Data Service for Paleoclimatology. It was last updated in 1997.
Use Cases
- Analyze fire frequency and return intervals using the calendar years before present (BP) timeline.
- Correlate fire event years with tree-ring width or density parameters to understand climate drivers.
- Map the geographic location of fire-scarred trees to reconstruct historical fire perimeters in Colorado.
Strengths
- Covers a long temporal span of 568 calendar years.
- Provides a specific geographic focus on Colorado, USA.
Limitations
- Data is temporally stale, last updated in 1997.
- The exact sample size (number of tree cores or sites) is unknown.
- Calendar year 'BP' scale requires careful handling for modern date conversion.
