Daily burned area, carbon emissions, and ignition location data for boreal fires in Alaska, Yukon, and Northwest Territories. The dataset covers an 18-year period from 2001 to 2018 at a 500-meter resolution. It was produced by ORNL_CLOUD using MODIS satellite data and fire perimeter databases.
Use Cases
- Model daily carbon emissions using per-pixel consumption estimates and environmental predictor variables like temperature and drought code.
- Analyze spatiotemporal patterns of fire ignition locations extracted from the daily burned area maps.
- Correlate burned area estimates with remote sensing indicators of burn severity and tree cover.
- Assess uncertainty in emission estimates derived from the statistical model linking field data to satellite observations.
Strengths
- 18-year temporal coverage from 2001 to 2018 provides a long-term record.
- 500-meter spatial resolution offers detailed geospatial analysis.
Limitations
- Data ends in 2018, lacking recent fire seasons.
- Uncertainty estimates are model-derived and dependent on the underlying statistical relationships.
Provenance
- Source
- ORNL_CLOUD, utilizing MODIS Collection 6 data and Alaskan/Canadian Large Fire Databases.
- Collection Method
- Burned area retrieved by combining fire perimeters with MODIS surface reflectance and active fire data. Carbon consumption estimated via a statistical model updated from the AKFED approach.
- Time Range
- 2001-01-01 to 2018-12-31
- Freshness
- Data is static, last updated at the end of the covered period in 2018.
- Geography
- Boreal regions of Alaska (USA), Yukon Territory, and Northwest Territories (Canada).
