Abstract
A new technique has been developed to obtain the total ozone content (TOC) under cloudy conditions from the spectra of outgoing thermal IR radiation measured by a satellite IRFS‑2 spectrometer. Analysis of the technique errors has shown that the differences between the obtained TOC and independent satellite (OMI) and ground-based (Dobson, Brewer, and M-124 instruments) measurements are usually 3–5%. The highest differences (up to 10%) are observed in the southern polar latitudes in the presence of an ozone hole over Antarctica. IRFS‑2 allowed the study of ozone miniholes over Russia in the first quarter of 2016. The measurements show an almost twofold decrease in TOC on certain days.
