摘要
利用美国防卫气象卫星计划(OMSP)特别微波辐射/成像计(SSM/I)的多通道微波辐射亮温数据,开展中国陆地区域陆地表面温度反演研究,选择1997年7月20/24日的SSM/I数据,先对中国陆地区域的数据进行处理与成像,然后基于Holliger算法利用七个通道数据进行地表类型分类,最后利用SSM/I数据的统计算法进行中国区域内的陆面温度反演研究,并用NOAA-AVHRR反演的温度数据进行分析比较,其结果与实际情况基本一致,研究结果表明,SSM/I微波辐射计数据可以为大面积的陆面温度反演提供快速的研究方法,为全球变化研究提供一种新资料。
In this paper,microwave radiation brightness temperature data from Special Sensor Microwave/Image(SSM/I)in America Defense Meteorological Satellite Program(DMSP)are used to conduct a study about China land surface temperature retrieval. SSM/I data selected was scanned on July 20 and 24,1997. At first,the SSM/I data covering China land surface is processed and imaged. Then,types of the land surface are classified based on an algorithm described in Holliger’s report using the seven channels. At last,the retrieval of China land surface temperature is carried out by using a statistic method based on SSM/I multiple channel data. The result was validated by the retrieval of AVHRR brightness temperature data. There is a good trend between the result of SSM/I data and the result of AVHRR data. The result shows that SSM/I microwave radiometer data provides a fast study method to land surface temperature retrieval on a large area.
