Abstract
Fires will not only affect the natural environment and human health, but also the satellite sensor for detecting infrared signals because of the strong infrared radiation. Based on statistical methods and visual analysis, this paper analysed the fire product data from 2015 to 2018 provided by the Visible Infrared Imaging Radiometer Suite (VIIRS) to understand the spatial and temporal distribution characteristics of global fires. The research contains the following results: the spatial distribution of global fires is basically the same in different years; The global fires are mainly concentrated between 45°S∼75°N latitude zone; The maximum of global fires for four years occurred in August, and minimum in May; The monthly number of fires in different latitude bands has a significant periodicity; The mainly distribution of fires are shifted in the northern and southern hemispheres with seasonal changes. The research results will lay the foundation for studying the distribution and type discrimination of fires.
