Results of ultrafine aerosol measurements on South-Eastern coast of the Lake Baikal (st. Boyarsky)

摘要

The results of ultrafine aerosol measurements in the atmosphere of South-Eastern coast of the Lake Baikal in summer 2019 are presented. The daily variation of aerosol concentration was established, which is characterized by an increase of concentration in the daytime and evening hours. The average value of total number concentration of ultrafine aerosol during the observation period was 2150 particles/cm~3. It is shown that the position of modal diameter in particle size distribution changes depending on the ambient air temperature.
