应用静止卫星热红外遥感亮温资料反演地表温度的方法研究

STUDY ON THE INVERSION METHOD OF LAND SURFACE TEMPERATURE BY APPLYING IR BRIGHT TEMPERATURE DATA OF STILL SATELLITE

双通道多时相反演方法在提取地表温度场时可把地表温度与地表发射率分离计算,是利用静止卫星热红外遥感资料研究地表温度场变化的一种有效方法。该方法计算简单,易于实现海量资料处理,基本满足红外遥感资料在地震预报中的应用要求。

The inversion method of two-pass,diversified temporal phases can calculate the land surface temperature and the land surface emissivity individually when attaining the land surface temperature,is a good way for researching the variation of land surface temperature field by applying IR data of still satellite.The method is easy to realize processing mass data with simple computation,and is able to fulfil request on applying IR data to earthguake prediction.
