MODIS/Aqua MYD14A2: Global Fire Detection at 1km Resolution

MYD14A2 Version 6.1 provides 1 kilometer spatial resolution thermal anomaly and fire data as a Level 3 product. The Aqua Moderate Resolution Imaging Spectroradiometer (MODIS) 8-day composite contains maximum values of individual fire pixel classes and Science Dataset layers for fire mask and pixel quality. The data is produced by the National Aeronautics and Space Administration and was last updated in March 2026.

Use Cases

• Monitoring global wildfire activity based on the 8-day fire pixel composite.
• Analyzing land surface thermal properties based on the thermal anomalies data.
• Assessing fire detection pixel quality based on the Science Dataset layers.
• Studying changes in fire detection algorithms based on Version 6.1 calibration improvements.
• Mapping fire occurrence patterns based on the 1km gridded spatial resolution.

Strengths

• Version 6.1 includes calibration improvements for reflectance and infrared bands.
• Data is provided at a 1 kilometer spatial resolution.
• Includes Science Dataset layers for fire mask and pixel quality indicators.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Known issues are documented externally, requiring additional review.
