Daily Global 1km Satellite Fire and Thermal Anomaly Data

Eight consecutive days of fire data are packaged into a single file generated every eight days at 1-kilometer resolution. The Terra MODIS instrument provides this Level 3 product containing fire mask, quality indicators, maximum fire radiative power, and fire pixel position. The data is produced by LPCLOUD from the MODIS/Terra sensor.

Use Cases

• Detect and map active fire locations globally using the daily fire mask layer.
• Analyze fire intensity and energy output trends with the maximum fire radiative power (MaxFRP) feature.
• Assess data reliability for specific pixels using the included pixel quality indicators.
• Study fire scan geometry and sensor observation characteristics from the fire pixel position data.
• Monitor eight-day fire activity cycles by aggregating the consecutive daily layers per file.

Strengths

• Global spatial coverage at 1-kilometer resolution.
• Includes eight consecutive days of daily per-pixel data in a single file.
• Provides multiple Science Dataset layers: fire mask, quality indicators, MaxFRP, and fire position.

Limitations

• Temporal resolution is every eight days, not daily, which may miss short-duration fire events.
• Known data issues exist, requiring users to consult the MODIS Land Quality Assessment website.
• Specific sample size, row count, and complete temporal range are not provided in the input.
