Level-2 swath data provides daily global fire detection at 1-kilometer resolution. Products are derived from MODIS 4- and 11-micrometer radiances and include fire-mask, algorithm quality, radiative power, and fire pixel attributes. The Aqua MODIS instrument, managed by LANCEMODIS, acquires data twice daily.
Use Cases
- Mapping active fire locations globally using the fire-mask layer.
- Analyzing fire intensity and energy output via the radiative power feature.
- Assessing detection reliability and potential false alarms with the algorithm quality layer.
- Studying diurnal fire patterns by combining Aqua (1:30 PM/AM) and Terra (10:30 AM/PM) observations.
- Monitoring fire pixel attributes like temperature and background contrast for process modeling.
Strengths
- Provides four daily global observations from Aqua and Terra MODIS instruments.
- Fire detection employs multiple tests to reject false alarms from sun glint or coastlines.
- Data is available at 1-kilometer spatial resolution.
Limitations
- Specific row count, temporal coverage, and sample size are unknown.
- Column definitions and data formats are unspecified.
- License and update frequency details are not provided.
