We report on a novel, medium weight (∼ 25 kg) optical spectrometer coupled to an automated sun tracker (∼ 12 kg) for direct sun observations from azimuth controlled balloon platforms. It is designed to measure a suite of UV/vis absorbing gases (O3, NO2, BrO, OClO, HONO and IO) relevant in the contex...
