Technical equipment of ground-based stations for total ozone measurements in Russia and prospects of modernization

Changes in the total ozone in the Earth’s atmosphere affect both the observed atmospheric changes and the climate of our planet. Ground-based measurements of the total ozone in the Russian Federation are carried out with the use of Dobson and Brewer spectrophotometers and SAOZ spectrometers; M-124 filter ozonometers are used in the Russian ozone network. In the near future, we will start the installation and trial operation of up-to-date automated UVOS spectrometers for observations of the total ozone and UV radiation. The work describes the main specifications of equipment used in ground-based measurements of the total ozone in Russia. The problems of modernization of the national network for the total ozone and UV solar radiation monitoring are considered.
