Abstract Forest fires have become a critical factor that affects the terrestrial ecosystems, and remote sensing is an important means for obtaining surface information. MODIS images have the merits of high spatial resolution and multispectra. A study of MODIS data can yield important data resources. The authors used near infrared, middle-far infrared, far infrared and thermal infrared MODIS bands to monitor the forest fires, mainly based on the MODIS 7 band and using Direct Criterion Method for high-temperature fires and Comprehensive Threshold Discrimination for non-high-temperature fires. It is proved that fire monitoring has very importan
