Donnegan Fire History from Al Gulch Tree Rings

NOAA/WDS Paleoclimatology's Donnegan fire data provides a fire history reconstruction from tree-ring analysis. The dataset covers a time period from 637 to -47 calendar years before present (BP), sourced from the Al Gulch site in Colorado, USA. It was archived by NOAA National Centers for Environmental Information (NCEI) and last updated in 1997.

Use Cases

• Reconstruct fire event years using tree-ring fire scar data.
• Analyze fire frequency and return intervals over the 684-year period.
• Correlate fire history parameters with other paleoclimate proxy records for Colorado.

Strengths

• Covers a long temporal range of 684 calendar years (637 to -47 BP).
• Sourced from the authoritative NOAA NCEI World Data Service for Paleoclimatology.

Limitations

• Data is temporally stale, last updated in 1997.
• Geographic scope is limited to a single site (Al Gulch, Colorado).
• Specific sample size (row count) and measurement parameters are not detailed in the provided metadata.
