一种新的卫星热红外遥感信息数据源:EOS/MODIS数据

A New Data Source of Satellite Thermal Infrared Remote Sensing Information: EOS/MODIS Data

概略介绍了四川省地震局近年来所开展的卫星遥感热红外辐射信息用于地震监测预报的研究工作及其进展 ;对目前地震系统卫星遥感热红外辐射信息研究工作所使用的数据源进行了比较 ;着重介绍了一种新的卫星热红外遥感信息数据源———搭载于美国地球观测系统 (EOS)的Terra和Aqua极轨卫星上的中分辨率成像光谱仪(MODIS)这一唯一进行直接广播的对地观测仪器的基本参数及数据特性。对MODIS数据与目前正在使用的AVHRR数据进行对比分析后认为 ,EOS/MODIS数据的产生 ,将进一步推动利用卫星热红外辐射资料研究强震前的热异常场的工作 ,并可望在我国地震监测预报实践中得到应用。

Briefly introduces the recent research work and developments on application of the satellite remote sensing thermal infrared radiation information to the seismic surveillance and earthquake predictions conducted by the Seismological Bureau of Sichuan Province; compares the data source used in the recent research work of the satellite remote sensing thermal infrared radiation information of the seismological system; emphatically introduces the fundamental parameters and data features of a new data source of satellite thermal infrared remote sensing information—? ﹎oderat e resolution imaging spectroradiometer (MODIS) on the polar orbit satellite Terra and Aqua of the Earth Observation System (EOS) of the United States, which is a unique observational instrument that directly broadcasts to the earth. Comparing the MODIS data with the AVHRR data being used now, the authors hold that the emergence of the EOS/MODIS data will further promote the application of satellite thermal infrared radiation data to the research work of thermal anomalous fields before strong earthquakes, and could be used in the practice of seismic surveillance and earthquake prediction of China.
