【摘要】 <正> 随着遥感技术的迅速发展和推广应用,近年来一些渔业先进国家(如美、苏、日等国)纷纷开展卫星遥感技术在渔业上应用的实验研究。从目前所见报道来看,卫星遥感技术还不能直接“观测到”鱼群,只是提供与渔场有关的海洋及生物学的信息。通过卫片判读可以获得海表温度、海流、水色、叶绿素、海冰、油污染、海上气象等环境参数,并绘制这些参数更多还原

【Abstract】 This paper describes a simple method of extracting characteristics information of fishery (sea-surface temperature) from infrared cloud pictures of the NOAA satellite and the calculation process drawing explanation chart,with the equation of the calculation process expressed as follows:The explanation chart provides us with the distribution of sea-surface temperature and cold-warm water system fronts in the Bohai,the Yellow and the East China Seas as well as the variations of the current rip in time and space.In winter and spring,the overall mean absolate error of the calculated temperature is about 1.0********C and the correlation coefficient is 90 percent or more,as compared with the shipmeasured surface temperature.更多还原
