2005年10月在广西武鸣机场进行了一系列的人工火情测量试验。进行的100 m2与200m2火场同步观测试验表明,在EOS-TERRA、EOS-AQUA和FY-1D等气象卫星遥感图像的人工火场区,中波红外通道均有明显的增温效应,达到了现行业务火情监测的判识标准,表明气象卫星1 km分辨率的中波红外通道完全可以遥感监测到小至200 m2、甚至100 m2完全燃烧的火场。分析BOMEM MR-154 FT高光谱仪测定的火情光谱特征,发现在中波4.34~4.76μm光谱段的辐亮度比火情监测常用通道3.5~4.0μm有更强的响应关系。通过初步的大气辐射传输计算,结果表明此波段似为卫星遥感探测火情更为敏感和有效的通道。
October 2005 in Wuming Airport in Guangxi conducted a series of artificial fire measurement test. Simultaneous observation of 100 m2 and 200m2 firestorms showed that the artificial fire zone and the medium-wave infrared channel of EOS-TERRA, EOS-AQUA and FY-1D have obvious warming effect and reached the current business The fire monitoring criteria indicate that a 1 km resolution meteorological satellite medium-wave infrared channel can be remotely sensed as small as 200 m2 or even 100 m2 of fully combusted fire. By analyzing the fire spectrum characteristics of the BOMEM MR-154 FT spectrometer, it was found that the radiance in the 4.34 ~ 4.76μm band of the medium wave has a stronger response than that of the common channel of fire monitoring 3.5 ~ 4.0μm. Based on the preliminary calculation of atmospheric radiation transmission, the result shows that this band appears to be a more sensitive and effective channel for satellite remote sensing to detect fire.
