Fig. 1 - S1 (18.01.2022) - China will host the 2022 Winter Olympics in Beijing and neighbouring province.
Fig. 2 - S2 (13.01.2019) - Lying 90 km from Beijing, this view shows Olympic infrastructures being built, before snow was generated.
Fig. 3 - S1 (02.01.2022) - Yanqing alpine skiing, bobsled and luge infrastructures were opened on Mt Xiaohaituo in 2018 & 2019.
About 80% of the snow at the 2014 Games in Sochi, Russia, was manufactured. When South Korea hosted in Pyeongchang four years later, that share rose to 90%. 100% of the snow used in these games is artificial.
Fig. 4 - Landsat-8 (30.01.2014) - The Zhangjiakou zone in Hebei province is 220 km from Beijing was developed as a ski resort from 2008.
These Olympic games will be using artificial snow because of the rarity of natural snow in this region. Over the past four decades, average winter precipitation was only 7.9 millimeters in the arid Beijing-Zhangjiakou region which does not make it ideal for natural or manufactured snow.
