基于FY-3A/VIRR卫星资料的江西省大雾遥感监测
|
摘要
根据雾在可见光、中红外、长波红外通道的反射及辐射特性与云和地物存在差异,从纹理特征、光谱分布特征等方面对云雾的差异进行分析研究,并利用多波段阈值法对风云三号气象卫星遥感影像进行日间大雾信息提取。结果表明,FY-3A/VIRR遥感资料对江西省大雾的监测效果较好,可在大雾卫星遥感监测业务中推广应用。
Fog area can be monitored by satellite remote sensing technology. According to the reflection and radiation characteristics of fog in visible, mid infrared and long wave infrared channels, as well as the differences between cloud and ground objects, the differences between cloud and fog were analyzed from the aspects of texture characteristics and spectral distribution characteristics. In addition, the daytime fog experiment had been made by multi-channel threshold method with the data of FY-3 A satellite. The result showed that the FY-3 A/VIRR remote sensing data have good monitoring effect on fog in Jiangxi Province and was suitable to be applied in the fog remote sensing monitoring business.
