VNP47IMG: VIIRS Fire Combustion Efficiency Swath Data

NASA/NOAA Suomi NPP VIIRS FILDA-2 Modified Combustion Efficiency (MCE) Version 2 swath product (VNP47IMG) provides high-resolution fire monitoring data. It contains 83 variables for fire detection, Fire Radiative Power (FRP), Visible Energy Fraction (VEF), and MCE retrieval at 375-meter resolution in 6-minute orbit segments. 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 Modified Combustion Efficiency (MCE) retrievals.
• Detecting small and cool fire fronts using improved algorithms and visible band data at night.
• Estimating fire radiative power (FRP) to quantify fire intensity and biomass burning emissions.
• Analyzing the spatial distribution of active fires from 375-meter resolution swath data.

Strengths

• Contains 83 specific variables for detailed fire characterization, including FRP, VEF, and MCE.
• Provides high spatial resolution (375 meters) and frequent temporal sampling (6-minute swaths).
• Produced by NASA/NOAA, indicating authoritative satellite data processing and calibration.

Limitations

• Metadata completeness is low: column names, row counts, and exact file sizes are not provided on any platform.
• Known issues exist and require consulting external user guides and assessment websites for full understanding.
• Platforms list conflicting license information ('other-license-specified' vs. 'None').
