摘要

2019年10月24日(LST时间10月23日晚上)加州北部金凯德大火点燃期间，地球静止运行环境卫星-17 (GOES-17)野火探测能力得到证实。将遥感数据与ALERTWildfire火灾监控视频系统的观测数据进行对比后分析表明，在地面摄像机网络探测到初始近红外热源52 s后，GOES17短波红外图像中可以明显看到新出现的Kincade火灾热点。GOES-17高级基线成像仪火灾探测特征算法在着火后5分钟记录了火灾。这些观测结果代表了首次记录的火灾引发和卫星探测之间的比较数据集，从而为GOES-16/17野火探测提供了背景。

Ground-Based Corroboration of GOES-17 Fire Detection Capabilities During Ignition of the Kincade Fire

Corroboration of Geostationary Operational Environmental Satellite-17 (GOES-17) wildland fire detection capabilities occurred during the 24 October 2019 (evening of 23 October LST) ignition of the Kincade Fire in northern California. Post-analysis of remote sensing data compared to observations by the ALERTWildfire fire surveillance video system suggests that the emerging Kincade Fire hotspot was visually evident in GOES17 shortwave infrared imagery 52 s after the initial near-infrared heat source detected by the ground-based camera network. GOES-17 Advanced Baseline Imager Fire Detection Characteristic algorithms registered the fire 5 min after ignition. These observations represent the first documented comparative dataset between fire initiation and satellite detection, and thus provide context for GOES-16/17 wildland fire detections.
