VIIRS/JPSS2 Near-Real-Time 750m Fire and Thermal Anomaly Swath Data

Global satellite data provides near-real-time detection of active fires and thermal anomalies at a 750-meter resolution. The VJ214_NRT product, based on the MODIS Fire algorithm and produced by LANCEMODIS, uses brightness temperature statistics from VIIRS/JPSS2 bands M13 and M15 to label fire pixels. It offers continuity with NASA's MODIS fire products and supports both day and nighttime detection over land and water surfaces.

Use Cases

• Monitoring wildfire outbreaks and progression using latitude, longitude, and fire radiative power columns.
• Analyzing gas flaring over water bodies via the land pixel flag and detection confidence.
• Assessing background thermal conditions for climate studies using background M13 and M15 brightness temperature statistics.
• Validating fire detection algorithms with pixel M7 reflectance and reflectance mean absolute deviation data.
• Studying fire-cloud interactions through the number of adjacent cloud pixels feature.

Strengths

• Provides high-resolution (750m) fire detection, offering finer detail than the 1 km MODIS product it continues.
• Algorithm includes both absolute and contextual fire detection tests using M13 and M15 brightness temperature statistics.
• Supports 24/7 monitoring with day and nighttime detection capabilities over land and water.
• Dataset is maintained for near-real-time (NRT) access, with a documented update timestamp of 2026-03-12.

Limitations

• Key metadata such as total row count, dataset size, and complete column list are unavailable across all sources.
• Sources conflict on license information, with some specifying 'other-license-specified' and others listing 'None'.
• Fire pixel designation can be overridden under sun glint conditions or with insufficient background pixels, potentially affecting detection accuracy.
