The station is situated on the top of Mt. Waligaun, on the Tibetan plateau in Western China. The annual average temperature is -0.9°C. The predominant wind directions are from SW to NW (summer) and from ESE to NE (winter). Yearly average wind speed is 4.6 m/s. Annual precipitation (mostly in summer months) averages 350 mm. Mt. Waligaun is a remote site, located away from major industrial sources. The closest major settlement is Quiapuqia with a population of 30000, located 30 km to the west. The surrounding area is covered with grass (no trees), and the overall region is sparsely covered with vegetation. The building was reconstructed in 1999.
