VNP47MOD: VIIRS Fire Combustion Efficiency from Suomi NPP

85 variables provide fire detection and retrievals of Fire Radiative Power (FRP), fire Visible Energy Fraction (VEF), and Modified Combustion Efficiency (MCE). The NASA/NOAA Suomi NPP VIIRS FILDA-2 product is generated in 6-minute orbit segments at a 750-meter spatial resolution, designed to detect smaller and cooler fires using visible band observations at night. This dataset supports analysis of fire characteristics and combustion efficiency globally.

Use Cases

• Monitoring wildfire intensity and energy release based on Fire Radiative Power (FRP) retrievals.
• Assessing fire combustion efficiency and emission factors using the Modified Combustion Efficiency (MCE) variable.
• Detecting smaller and cooler fires, especially at night, using the enhanced FILDA-2 algorithm.
• Analyzing spatial and temporal patterns of active fires from 750-meter resolution swath data.

Strengths

• Contains 85 specific variables for detailed fire analysis, including FRP, VEF, and MCE.
• Provides high-resolution (750m) data in frequent 6-minute acquisition windows.
• Algorithm improvements enable detection of smaller and cooler fires than previous versions.

Limitations

• Metadata completeness is low: column names, row counts, and dataset size are unspecified across all sources.
• Known issues exist but are documented externally, requiring users to consult separate resources.
• Conflicting metadata: one source lists an 'other-license-specified' license while another lists 'None'.
