A research aerosol station has been installed on Bely island in the Kara sea to help determine the impact of emissions from burning fossil fuels, natural gas, and wildfires on the Arctic atmosphere. The station appeared thanks to the joint work of scientists from Moscow state University and their colleagues from the scientific center for the study of the Arctic (Salekhard)

 "Currently, assessment of the environment and climate change in the Arctic region is greatly complicated by the lack of knowledge on emission sources, the number and composition of aerosol pollution, which determines the impact on the Arctic ecosystem," - said a leading scientist of the Department of microelectronics SINP MSU Olga Popovicheva.

Indeed, Bely Island is the northernmost territory of the Yamalo-Nenets Autonomy District. It is located on the path of air masses that come to the Arctic from areas of Northern Siberia with high industrial activity.

According to the researchers, combustion of aerosols is the most ecologically and climatically significant component of the polluted atmosphere, and continuous measurements will allow analyzing the degree of load of the Arctic atmosphere with the climatically active component, black carbon, in order to determine the contribution of burning fossil fuels, natural gas and wildfires to the Arctic atmosphere.

It is also expected to determine the main characteristics of the background Arctic aerosol and seasonal variability trends during the Arctic haze.

First, in 2014, the island was established by the research hospital of the Russian center of Arctic exploration, and in 2015, scientists of the Institute of industrial ecology Ural branch of RAS mounted Picarro laser analyzer for continuous measurements of greenhouse gases. The data obtained today help to determine the sources and volumes of greenhouse gas emissions at a distance of up to a thousand kilometers.
