一、概述航天遥感是人们在大范围认识地球环境的有力手段,在众多的卫星系列中,气象卫星可以说最早进入了长期的成熟的业务运行阶段,它的意义不仅限于气象业务和研究,近期以来,在许多非气象领域,如海洋、森林火灾和洪水监测,农作物估产,捕渔,资源调查,环境监测等等方面的应用也越来越引起人们的关注,并已表明具有巨大的经济和社会效益。众所周知,气象卫星可提供大范围、多波段、高时效、长期的动态观测数据,而它最大的特点之一是这种丰富的数据信息的易获得性。这是一种全球性的、公开的、无偿的信息服务。随着近代电子技术的发展,气象卫星数据的接收和处理已变得不那么复杂和困难,地面
I. Overview Space remote sensing is a powerful means for people to understand the Earth’s environment in a wide range. Among many satellite series, meteorological satellites can be said to have entered the long-term and mature business operation stage at first. Its significance is not limited to meteorological services and research. Recently, It has also drawn increasing attention in many non-meteorological areas, such as oceans, forest fires and flood monitoring, crop assessment, fishing, resource surveys, environmental monitoring and so on, and has demonstrated the enormous economic and Social benefits. As we all know, meteorological satellites can provide large-scale, multi-band, high-time, long-term dynamic observation data, and one of its greatest features is the availability of such rich data and information. This is a global, open, unpaid information service. With the development of modern electronic technology, the receiving and processing of meteorological satellite data has become less complicated and difficult. The ground
