The possibilities of using a new class of spectral apparatus (video spectrometer) for determining atmospheric concentrations of BrO, ClO, OClO, NO₃, O₄, and SO₂ are analyzed. It is shown that using a video spectrometer for measuring the atmospheric transmission on tangential paths makes it possible to obtain, together with information about the content of components such as O₃ and NO₂, additional data on the vertical profiles of BrO, OClO, NO₃, and O₄ contents. -Authors
