Summary
Daqi-1 (AEMS) launched on a China Aerospace Science and Technology Corporation Long March 4C from Launch Complex 9, Taiyuan Satellite Launch Center, People's Republic of China on April 15, 2022. It was China Aerospace Science and Technology Corporation's 363rd launch, 11th this year and humanity's 6,222nd orbital launch attempt. It was the 43rd Long March 4C flight and the 5th this year. The payload was bound for Sun-Synchronous Orbit (SSO). Daqi Huanjing Jiance Weixing, one of 2 catalogued objects, reached a 688 × 697 km orbit inclined 98.1°. 2 objects from this launch are catalogued, one of them a payload.

About this launch
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.
