Spatio-temporal and causal analyses of "black summer" fires based on remote sensing satellites

This is the authors' abstract. We don't add key points for this paper.

Wildfires are a common natural disaster that threatens the environment, the economy, the climate, and even human life. It is therefore important to monitor the occurrence of fires to understand how they start, what causes them, and how they can be better prevented. Fires occur throughout the year in Australia, and 2019-2020 saw an unprecedented black summer of fires. These fires have caused tens of thousands of animal and plant deaths, massive property damage, and many casualties. Therefore, it is more meaningful to study a typical case like Australia as a research object. In this paper, by applying Arcgis to MODIS fire point data, it is possible to analyze them in time and space. The causes are also analyzed through the impact of Sentinel-2. The results show that the initial phase of the fires is from July to October 2019, peaking in December 2019 and starting to decline in mid-January 2020. Most of the fires were concentrated along the coastline, with fewer in the west. This is thought to be related to the classification of vegetation cover and rainfall in Australia.
