Abstract

In this study, we used bands 7, 4, and 3 of the Advance Himawari Imager (AHI) data, combined with a Threshold Algorithm and a visual interpretation method to monitor the entire process of grassland fires that occurred on the China-Mongolia border regions, between 05:40 (UTC) on April 19th to 13:50 (UTC) on April 21st 2016. The results of the AHI data monitoring are evaluated by the fire point product data, the wind field data, and the environmental information data of the area in which the fire took place. The monitoring result shows that, the grassland fire burned for two days and eight hours with a total burned area of about 2708.29 km2. It mainly spread from the northwest to the southeast, with a maximum burning speed of 20.9 m/s, a minimum speed of 2.52 m/s, and an average speed of about 12.07 m/s. Thus, using AHI data can not only quickly and accurately track the dynamic development of a grassland fire, but also estimate the spread speed and direction. The evaluation of fire monitoring results reveals that AHI data with high precision and timeliness can be highly consistent with the actual situation.

Summary

Introduction

Detection, and monitoring are key economic and public safety concerns in many parts of the world [1]. Autonomous Region is located between China and Mongolia, at the junction of the two countries. The border is 3193 km long, accounting for 68% of the total length of the border line between China and Mongolia [2,3]. Mongolia is sparsely populated, has weak firefighting capabilities, as well as less precipitation in spring and autumn, dry weather, and a large number of gale-force wind days. Grassland fires occurring in the China-Mongolia border regions are often spread into Inner.
