VIIRS FILDA-2: Fire Combustion Efficiency from NOAA-20 Satellite

The VIIRS FILDA-2 Modified Combustion Efficiency (MCE) Version 2 swath product (VJ147IMG) is a satellite-derived dataset from the NOAA-20 satellite. It provides 83 layers of fire detection data, including retrievals of Fire Radiative Power (FRP), Visible Energy Fraction (VEF), and Modified Combustion Efficiency (MCE) at a 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

• Monitoring fire intensity and energy release based on Fire Radiative Power (FRP) retrievals.
• Assessing fire combustion efficiency and emission characteristics based on Modified Combustion Efficiency (MCE) and Visible Energy Fraction (VEF) layers.
• Detecting smaller and cooler fires, especially at night, based on improvements in the fire detection algorithm.
• Analyzing spatial patterns of active fires at a 375-meter resolution from swath data.

Strengths

• Contains 83 distinct data layers for detailed fire analysis.
• Provides high-resolution (375-meter) fire observations in 6-minute temporal segments.
• Utilizes an advanced algorithm designed to detect smaller and cooler fires, enhancing detection capability.

Limitations

• Column names and specific data structure are not provided in the metadata.
• Dataset size and row counts are unknown across all sources.
• Known issues exist and require consultation of external user guides and assessment websites.
