MOD14A2: Terra MODIS 8-Day Global Fire and Thermal Anomalies at 1km Resolution

Global data on thermal anomalies and fire detection generated from the Terra MODIS satellite at 1 kilometer spatial resolution. The National Aeronautics and Space Administration produced this Level 3 product, which provides an 8-day composite of the maximum fire pixel classes. This version was decommissioned on July 31, 2023, with users directed to the updated Version 6.1 product.

Use Cases

• Monitoring global wildfire activity based on the 8-day composite fire mask.
• Analyzing thermal anomaly patterns over land and water, including detection from oil rigs.
• Improving fire detection algorithms by studying refinements like dynamic thresholding for small fires.
• Assessing data quality for regions with heavy smoke or forest clearings using the described cloud mask and false alarm fixes.

Strengths

• Provides global coverage at 1 kilometer spatial resolution.
• Includes refinements such as a fix for frequent false alarms in the Amazon and detection of fires over water pixels.
• Documented known issues and version improvements are available via the MODIS Land Quality Assessment website and User Guide.

Limitations

• The dataset was decommissioned on July 31, 2023, indicating it is not the current operational version.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and specific temporal coverage are unknown, which may limit suitability assessment.
