The expedition team departed from the assault camp at 5,700 meters in altitude on Friday.

Five automatic weather stations have been set up at altitudes of 4,950, 5,700, 6,450, 7,100 and 8,201 meters on Mt. Cho Oyu, which will help reveal characteristics of climate change in extremely high-altitude areas, said Zhao Huabiao, a researcher with the Institute of Tibetan Plateau Research under the CAS.

After the expedition team set up a weather station at the altitude of 8,201 meters, the meteorological data was successfully transmitted, showing that the temperature at the summit of Mt. Cho Oyu was minus 18 degrees Celsius.
