There are four national level field stations in 14 key regions of China.

Wei Waliguan global atmospheric background field station

  The Waliguan global atmospheric composition background field research station was established in 1989, which is called Waliguan station for short. Following the WMO / GAW technical specification system, it carries out the observation of greenhouse gases and related trace components, total ozone, precipitation and aerosol chemistry, optical properties, reactive gases, meteorology and other elements.

Wei Longfeng Mountain atmospheric composition background field research station

  The Longfengshan station was established in 1991. It mainly carries out the observation of greenhouse gases, aerosols, reactive gases, total and profile of ozone column, climate and conventional meteorological elements.

Wei Lin'an atmospheric composition background field observation station

  Lin'an atmospheric composition background field observation and research station was established in 1983, referred to as Lin'an station. It mainly carries out the observation of acid rain, atmospheric turbidity, total suspended solids, greenhouse gases, aerosols and chemical components, reactive gases, total ozone column and conventional meteorological elements.

Wei Shangdianzi atmospheric composition background field research station

  Shangdianzi atmospheric composition background field research station was established in 1981. It mainly carries out the observation of greenhouse gases, aerosols, reactive gases, ozone column total and profile, climate and conventional meteorological elements.
