VJ147MOD: VIIRS Fire Combustion Efficiency and Detection Swath Data

The VIIRS/JPSS1 FILDA-2 Fire Modified Combustion Efficiency Product (VJ147MOD) is a 750-meter resolution swath dataset produced in 6-minute orbit segments from the NOAA-20 satellite. It contains 85 layers for fire detection and retrievals of Fire Radiative Power (FRP), Visible Energy Fraction (VEF), and Modified Combustion Efficiency (MCE). The algorithm leverages visible band observations at night to assess combustion efficiency and detect smaller, cooler fires.

Use Cases

• Assessing fire combustion efficiency based on the Modified Combustion Efficiency (MCE) layer.
• Estimating fire radiative power and energy output using the Fire Radiative Power (FRP) retrieval.
• Detecting smaller and cooler fires, especially at night, using the enhanced FILDA-2 algorithm.
• Analyzing the spatial distribution of active fires from 750-meter resolution swath data.

Strengths

• Contains 85 distinct data layers for detailed fire analysis.
• Provides high-resolution (750m) data in frequent 6-minute orbit segments.
• Cross-platform presence on NASA Earthdata and Data.gov indicates established use and importance.

Limitations

• Column names and dataset size are unspecified across all sources.
• License is ambiguously listed as 'other-license-specified' or 'None'.
• Known issues require consulting external documentation, indicating potential data quality caveats.
