综合利用可见光、红外和微波卫星观测资料，对我国西北地区沙尘暴进行了探测。微波测量用于探测冰云下的沙尘暴，而可见光和红外测量用于描绘无云的沙尘系统。检测是基于89 GHz和23.8 GHz两个通道之间的微波偏振亮度温差（Δ T-b=T-bv -T-bh）和11和12 μ m通道之间的红外亮度温差（BTD）。结果表明，该方法在风暴探测中优于单纯的红外BTD方法，特别是对于那些被冰云覆盖的沙尘系统。利用Aqua卫星上的中分辨率成像光谱仪（MODIS）和高级微波扫描辐射计（AMSR-E）的数据，将这种方法应用于亚洲沙尘暴的情况。(c)2007年爱思唯尔公司All rights reserved.
Observations from visible, infrared and microwave satellite instruments are integrated to detect dust storm over northwestern China. Microwave measurements are used to detect the dust storm underneath ice clouds, while visible and infrared measurements are utilized for delineating the cloud-free dust systems. Detection is based on microwave polarized brightness temperature differences (Delta T-b=T-bv -T-bh) among two channels of 89 GHz and 23.8 GHz and infrared brightness temperature difference (BTD) between channels at 11 and 12 mu m. It is shown that the integrated approach is better than the method solely based on infrared BTD in storm detection, especially for those dust systems covered by ice clouds. This approach is applied for the Asia dust storms cases using the data from the Moderate Resolution Imaging Spectroradiometer (MODIS) and the Advanced Microwave Scanning Radiometer (AMSR-E) onboard Aqua satellite.
