VJ114_NRT: VIIRS Satellite Active Fire Detection at 750m

Global satellite data provides near real-time detection of thermal anomalies and active fires at a 750-meter spatial resolution. The dataset is derived from the VIIRS/JPSS1 sensor using a contextual algorithm based on brightness temperatures in the M13 and M15 bands. It offers continuity with NASA's MODIS fire product and supports day and nighttime detection over land and water, including gas flares.

Use Cases

• Monitoring wildfire spread and intensity based on fire radiative power (FRP) measurements.
• Detecting industrial gas flares over water bodies using the day/night active fire detection capability.
• Validating fire models and assessing burn severity using contextual background brightness temperature statistics.
• Supporting emergency response and resource allocation by providing fire pixel coordinates and detection confidence.

Strengths

• Provides data continuity with NASA's established MODIS 1 km fire product.
• Offers near real-time (NRT) delivery, suitable for operational monitoring.
• Includes multiple detection confidence metrics and contextual pixel statistics for validation.

Limitations

• Metadata for row count, size, and specific column names is unavailable across all sources.
• Fire detection may be overridden under sun glint conditions or with insufficient background pixels, as noted in the algorithm description.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
