Abstract

Monitoring of the total content of ozone, which is one of the most climatically and ecologically important gases, is currently carried out using polar, geostationary, and highly elliptical satellites (Arktika-M). The paper compares measurements of total ozone (TO) with the MSU-GS radiometer on the Arktika-M satellites with ground-based measurements using the Bruker 125HR Fourier spectrometer and IKFS-2 and TROPOMI satellite instruments. It is shown that MSU-GS measurements on the Arktika-M highly elliptical satellites allow obtaining valuable information on TO with a high spatial (4 km) and temporal (15 minutes) resolution, taking into account the observed variations in TO under conditions of “ozone holes” reaching 50% and more and leading to increases in dangerous ultraviolet solar radiation.
