#### Description

The MOD14A1 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.
