The official news agency Xinhua reported on September 5, 2018, that China installed its first independently-developed atmosphere observation system known as APSOS in the Tibet Autonomous Region. Lyu Daren, head of the APSOS project and academician in the Chinese Academy of Sciences, was quoted as saying the APSOS, or Atmosphere Profiling Synthetic Observation System, is a ground-based facility for profiling atmospheric variables and multiple constituents in the atmosphere. Installed in the Yangbajing International Cosmic Ray Observatory, it is capable of monitoring atmospheric compositions such as temperature, wind speed, and ozone and carbon dioxide levels. He added that "The system is installed in the Qinghai-Tibet plateau because the region plays an important role in affecting climate and environmental changes globally."
