Fumarole composition and SO2 flux results acquired on 6 October 2017 at Minas de Azufre, a persistent fumarolic field topping the resurgent Sierra Negra caldera, in the Galápagos archipelago. The data listed here are the raw Multi-GAS data acquired during a walking traverse through the furmarolic field (used to draw Figures 2 in Aiuppa et, 2021, submitted), and the processed UV Camera results (used to draw Figure 3 in Aiuppa et 2021, submitted)..
