VIIRS NOAA-20 Active Fire Detections at 375m Resolution

Near real-time global fire detection data from the NOAA-20 satellite's VIIRS instrument. The product provides 375-meter resolution active fire locations, offering improved mapping of small fires and large fire perimeters compared to coarser resolution products. It is produced by LANCEMODIS for fire management and scientific applications.

Use Cases

• Near real-time fire alerting systems based on active fire detection data.
• Mapping fire perimeters for wildfire research based on the 375-meter resolution.
• Monitoring small-scale fire activity based on the improved spatial response.
• Supporting continuity studies with other satellite fire data records.

Strengths

• Provides 375-meter nominal resolution, which is finer than many other satellite fire products (≥1km).
• Designed for near real-time (NRT) availability, supporting operational use.
• Offers improved response over small fires and better mapping of large fire perimeters.

Limitations

• Provides detection information only with no sub-pixel fire characterization due to data saturation issues.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and file size are unknown, which may limit suitability assessment.
