全球火灾地图集（2003-2016）
全球火灾地图集是一个新的可免费使用的全球数据集，它跟踪单个火灾的日常动态，以确定点火的时间和地点、火灾规模和持续时间，以及每日扩张、火线长度、速度和蔓延方向。数据以容易获取的GIS图层形式提供，也可以在这里进行在线探索，Andela等人（2019）对基本方法进行了详细描述。前言 – 人工智能教程
这些数据提供了对引起世界上最极端野火的环境条件的独特见解。世界上最大的野火出现在澳大利亚内陆、非洲和中亚地区人口稀少的干旱和半干旱草原和灌木丛中。令人震惊的是，在北美洲和南美洲的类似生态系统中，几乎没有这些比例的火灾，这可能是由于较高的景观破碎化和不同的管理做法，包括积极的灭火。
虽然世界上最大的火灾发生在更干旱的生态系统中，但最长的火灾在潮湿的热带和高纬度森林的季节性地区燃烧了两个多月。在这些人口稀少的高燃料负荷系统中，只要天气条件有利，火灾就能持续燃烧。异常的天气条件往往使多个极端野火在较大区域内同步发生。全球的火速模式与燃料负荷呈反向关系，最高的火速通常发生在低燃料负荷地区。
