We report on a novel, medium-weight ( ∼ 25 kg ) optical spectrometer coupled to an automated sun tracker for direct sun observations from azimuth-controlled balloon platforms weighing approximately 12 kg . It is designed to measure a suite of UV–Vis absorbing gases relevant in the context of stratos...
