MYD14A1.061: Aqua Thermal Anomalies & Fire Daily Global 1km

  • The MYD14A1 V6.1 dataset provides daily global fire mask composites at 1km resolution, distinguishing between fire, no fire, and no observation.

  • This dataset, derived from MODIS, uses a fire detection strategy based on absolute and relative fire strength detection for accurate identification.

  • It's used to monitor fire distribution, detect changes, and identify new fire frontiers, wildfires, and frequency changes.

  • The data is freely available for use, sale, or redistribution with proper citation to the LP DAAC.

  • Users can explore the dataset using Earth Engine, a platform for scientific analysis and visualization of geospatial datasets.

Description

The MYD14A1 V6.1 dataset provides daily fire mask composites at 1km resolution derived from the MODIS 4- and 11-micrometer radiances. The fire detection strategy is based on absolute detection of a fire (when the fire strength is sufficient to detect), and on detection relative to its background (to account for variability of the surface temperature and reflection by sunlight). The product distinguishes between fire, no fire and no observation. This information is used for monitoring the spatial and temporal distribution of fires in different ecosystems, detecting changes in fire distribution and identifying new fire frontiers, wild fires, and changes in the frequency of the fires or their relative strength.
