VNP14IMG_NRT: Near Real-Time VIIRS 375m Active Fire Detection

Global satellite data from the Suomi NPP satellite's VIIRS instrument provides near real-time detection of active fires and thermal anomalies at a 375-meter spatial resolution. The dataset is a Level 2 product generated using a multi-spectral contextual algorithm that leverages five 375m and complementary 750m channels to distinguish fires from land, water, and cloud pixels. It is processed through NASA's Land, Atmosphere Near real-time Capability for EOS (LANCE) and provides continuity for the heritage MODIS fire product.

Use Cases

• Real-time wildfire monitoring and alerting based on the near real-time (NRT) processing capability.
• Analyzing fire dynamics and spread using the 375-meter spatial resolution thermal anomaly data.
• Validating and improving fire detection algorithms by comparing with the heritage MODIS 1 km product.
• Assessing land surface thermal properties and radiative energy from detected sub-pixel fire activity.

Strengths

• Provides high-resolution fire detection at 375 meters, offering finer detail than the 1 km MODIS heritage product.
• Features near real-time (NRT) availability through NASA's LANCE system, supporting time-sensitive applications.
• Uses a validated multi-spectral algorithm described in peer-reviewed literature (Schroeder et al., 2014).

Limitations

• Metadata on dataset size, row count, and specific column schema is unavailable across all sources.
• Conflicting file format information exists between sources (NetCDF4 vs. HDF4), requiring user verification.
• License is ambiguously specified as 'other-license-specified' without explicit terms provided.
