China has set up a background atmosphere observation site at its Zhongshan station on Antarctica as part of its 24th scientific expedition to the region.
Researchers at Zhongshan station will be able to observe surface ozone and gases like carbon monoxide, carbon dioxide, sulfur dioxide and nitrogen oxides, as well as black carbon aerosol.
Chinese scientists have monitored total ozone content for 15 years with their ground-based remote sensing system at the Zhongshan station on Antarctica, which provides ideal conditions for research on background atmosphere due to the area's lack of human activity.
Based on previous studies, they will continue observation and analysis of ozone and UV-B radiation in the area around the station.
According to scientists at Zhongshan station, they are also planning to go further into the Antarctic ice sheet to conduct research on background atmosphere there.
