The unit is ppm. China Waliguan atmospheric background reference Observatory was established in 1994. It is located on the Qinghai Tibet Plateau with an altitude of 3810 meters. It is the highest atmospheric background reference monitoring station in the world and the first atmospheric background monitoring station in the hinterland of the mainland in the world. Its establishment fills the gap of the global atmospheric monitoring network (GAW) in Eurasia.
