NASA-FIRMS

Fire points are displayed in red on the map.
The time of data acquisition is in UTC (Coordinated Universal Time).
There are two sources of data: MODIS onboard both the Aqua and Terra satellites and VIIRS 375 m onboard the S-NPP and NOAA-20 satellite.
The improved spatial resolution of the VIIRS 375 m product (over the MODIS 1 km product) provides a greater response over fires of a relatively small area and has improved night time performance. As a result, users will notice many more fires are detected from VIIRS.
The MODIS confidence value is based on a collection of intermediate algorithm quantities used in the detection process. The range of confidence is expressed between 0-100 (the values range from 0=very low to 100=very high). The confidence field is experimental and should be used with caution; it is likely that it will vary in meaning in different parts of the world.

Reasons why MODIS or VIIRS may not have detected a certain fire: the fire started and ended between satellite overpasses; detection was obscured cloud cover, heavy smoke, or tree canopy. In addition for MODIS, fires may have been too small or too cool to be detected in the 1 km2 footprint.
