The data set reports on long term atmospheric observations (aerosol scattering and back scattering coefficient, surface ozone, and aerosol particle number concentration) at the Air Chemistry Observatory (Neumayer III, Antarctica) between 1 January 2025 and 31 December 2025, measured about 5-7 m above ground with 60 sec resolution.
