On 21 May 2016, two Differential Optical Absorption Spectroscopy (DOAS) instruments were used to measure the radiance of scattered solar radiation passing through the plume emitted from Sabancaya Volcano, Peru. Spectra were recorded in the ultraviolet (UV: 280 – 425 nm) and visible (Vis: 450 – 780 nm) wavelength ranges at 0.6 and 1.2 nm resolution, respectively. Two distinct experiments were performed using different measurement geometries. In the first experiment, two zenith-looking telescopes were mounted on a vehicle, each coupling scattered sunlight into one of the two DOAS spectrometers. The vehicle traversed beneath Sabancaya’s volcanic plume between 16:43 to 17:39 UTC collecting 2075 UV spectra and an equal...
