VJ114IMG: NOAA-20 VIIRS Active Fire Swaths at 375m

375-meter resolution satellite data from the VIIRS sensor aboard NOAA-20 detects fire locations and thermal anomalies in 6-minute swaths. The product includes 26 science dataset layers analyzing atmospheric conditions like radiance and brightness temperature, as well as fuel type. Each data swath covers an area approximately 3,060 by 3,060 kilometers.

Use Cases

• Mapping fire perimeters and intensity based on the fire mask layer.
• Analyzing atmospheric conditions for fire detection using radiance and brightness temperature variables.
• Studying thermal anomalies, including volcanic activity, from the primary fire detection layer.
• Generating higher-level fire data products for research and operational use.

Strengths

• Provides high-resolution (375m) fire detection data, enabling detailed spatial analysis.
• Includes 26 science dataset layers for analyzing key fire detection factors.
• Offers frequent temporal coverage with data produced in 6-minute satellite increments.

Limitations

• Column names and dataset size (rows, file size) are not specified in any source.
• Accurate geolocation requires a separate, mandatory data product (VJ103MODLL), adding complexity.
• One source lists 25 science dataset variables while others list 26, indicating a potential metadata conflict.
