Fire Frequency - AVHRR, Australian algorithm

Fire Frequency is derived from a time series of burnt area maps (derived from the Advanced Very High Resolution Radiometer (AVHRR)) and provides the average number of fires affecting an area in the given time period. It is the inverse of the fire return interval.

火灾频率（Fire Frequency）源自基于高级甚高分辨率辐射计（Advanced Very High Resolution Radiometer，AVHRR）反演得到的过火区时间序列地图，可表征给定时段内某区域受火灾影响的平均次数，其数值为火灾返回间隔（fire return interval）的倒数。
