Service Description: This is the sum of fires between 2013 and 2018 for each ~1 degree grid cell. Produced with MODIS Active Fire data. A fire is counted every time there is a satellite overpass (as long as the sky is clear), thus a fire burning for more than one day may be counted more than once.

An active fire represents the centre of a pixel flagged as containing one or more actively burning hotspots /fires. In most cases fires are vegetation fires, but sometimes it is a volcanic eruption or the flare from a gas well. There is no way of knowing which type of thermal anomaly is detected based on the MODIS data alone. https://earthdata.nasa.gov/firms-faq#ed-all-veg-fires

The satellite only detects fires at the time of overpass so the data could be thought of as a sample of the total fire occurrence (Giglio, 2010).
