任务简介
中国首颗专门用于大气环境综合监测的卫星，名为大气一号，也称大气环境监测卫星（AEMS），由位于上海的上海航天技术研究院（SAST）研制，设计运行在太阳同步轨道。大气一号可监测PM2.5等细颗粒物污染、包括二氧化氮、二氧化硫和臭氧在内的污染物气体，以及二氧化碳浓度。 据上海航天技术研究院的一位总设计师介绍，该卫星结合了被动和主动遥感，能够更好地实现大气环境的综合监测。该总设计师表示，大气一号对细颗粒物和二氧化碳柱浓度的探测精度已达到国际先进水平。卫星上搭载的大气探测激光雷达也是全球首台能够同时探测大气气溶胶和二氧化碳的激光雷达。

China’s first satellite dedicated to comprehensive monitoring of the atmospheric environment, named Daqi-1, also known as Atmospheric Environment Monitoring Satellite (AEMS) and developed by the Shanghai Academy of Spaceflight Technology (SAST) in Shanghai, is designed to operate in sun-synchronous orbit. Daqi-1 can monitor fine particle pollution like PM2.5, pollutant gases including nitrogen dioxide, sulfur dioxide and ozone, as well as carbon dioxide concentration. It combines both passive and active sensing, which can realize comprehensive monitoring of the atmospheric environment in a better way, according to a chief designer with SAST. The detection accuracy of fine particles and carbon dioxide column concentration by Daqi-1 has reached the international advanced level, the chief designer said. The atmospheric detection lidar deployed on the satellite is also the world's first that is capable of detecting both atmospheric aerosols and carbon dioxide.
