| 摘 要： | 风云二号静止气象卫星上装载有可见光、中波红外、水汽和红外波段探测通道,其中白天的中波红外通道反射率可以反映云顶粒子的尺度和相态信息.联合使用可见光、中波红外和热红外通道辐射,可构建白天云顶粒子相态识别算法.云相态识别结果与CloudSat卫星的云分类产品相比较,个例分析表明,两种数据对于以深对流和卷云为主的高层冰云识别...

| Abstract: | FengYun-2 geostationary spectral data consists of 5 channels that locate at visible,near infrared,water vapor and far infrared wavelength.Among these channels,the reflectance of near infrared bands at daytime is the function of cloud particle's size and thermodynamic phase.The paper proposes a grouped detection method to identify cloud particle's thermodynamic phase by reflectance of visible,near infrared bands,and brightness temperature of infrared bands.The identified cloud phase was compared with CloudSa... |
