MODIS/Aqua MYD14A2: Global 8-Day Fire and Thermal Anomaly Data at 1km Resolution

MYD14A2 Version 6 is a decommissioned NASA Aqua MODIS data product for global fire and thermal anomaly detection. The 8-day composite provides maximum fire pixel values at 1-kilometer spatial resolution, including fire mask and quality indicator layers. Users are directed to the updated MYD14A2 Version 6.1 product.

Use Cases

• Monitoring global wildfire frequency and location based on the 8-day fire mask composite.
• Analyzing land surface thermal properties using the thermal anomalies data layer.
• Assessing detection confidence for fire events based on the included pixel quality indicators.
• Studying fire detection over water bodies, including from oil rigs, as mentioned in the version improvements.

Strengths

• Provides global spatial coverage at 1-kilometer resolution.
• Includes specific improvements for reducing false alarms in the Amazon and detecting small fires via dynamic thresholding.
• Processes ocean and coastline pixels to detect fire from sources like oil rigs.

Limitations

• This specific version (V006) was decommissioned on July 31, 2023, requiring users to migrate to the newer version.
• Known issues, such as heavy smoke being flagged as clouds, are documented but require external review.
• Column-level documentation is absent; field semantics must be inferred after download.
