Abstract

The aim of this work was to evaluate the performance of the FMA+ fire index for the Serra do Tombador Natural Reserve region in Cavalcante, Goiás. The dataset was composed of records provided by the reserve’s meteorological station and hotspot detection by satellites. The period analyzed was from 2016 to 2020. The index was fitted by modifying the limits of the fire hazard classes of the FMA+, where: a) the distribution of the number of days in each class presented decreasing behavior; and b) the number of days with hotspots by hazard class presented increasing behavior. The performance was evaluated through the skill score and accuracy methods. The FMA+ index received a skill score of 0.5 and accuracy of 75%, but it was necessary to adjust the classes to reach those levels. The results indicated that the adjusted FMA + index was suitable for use in the study region.

巴西serra do tombador自然保护区fma +森林火灾危险指数的表现goiÁs

这项工作的目的是评估FMA+火灾指数在卡瓦尔坎特(Goiás)的Serra do Tombador自然保护区地区的表现。该数据集由保护区气象站提供的记录和卫星热点探测组成。所分析的时间段为2016年至2020年。通过修改FMA+的火灾危险等级限值拟合指数，其中:a)各火灾危险等级的天数分布呈递减趋势;b)危险等级出现热点的天数呈增加趋势。通过技能得分法和准确率法对其进行评价。FMA+指数的技能得分为0.5，准确率为75%，但有必要调整类别以达到这些水平。结果表明，调整后的FMA +指数适用于研究区。
