Field deployment of a man-portable stand-off laser-induced breakdown spectrometer: A preliminary report on the expedition to the Cumbre Vieja volcano (La Palma, Spain, 2021) Palanco-López, Santiago Pérez-López, Raúl Galindo-Jiménez, Inés Bernal, Alberto Rodríguez-Aranda, Sergio Eliseo López-Escalante, María Cruz Leinen, Dietmar Mediato, Jose F. López-Gutiérrez, Julio Ramos-Barrado, José Ramón Espectroscopía de plasma inducido por láser This paper reports on the expedition to the Cumbre Vieja volcano (Canary Islands, Spain) in November 2021 to assess stand-off laser-induced breakdown spectroscopy for real-time measurements of the lava streams from a safe point. The paper provides insight on the analytical approach to the problem, the rationale of the instrument design and construction carried out in three weeks, the experience with the new-born instrument at the volcano and the preliminary results. Despite the subtle spectral differences among the samples and the signal variability induced by the strong wind gusts at site, a statistical approach to data processing such as PCA, made possible to extract sufficient information and provide a robust classification tool. 2022-06-03T09:18:06Z 2022-06-03T09:18:06Z 2022-04 journal article Santiago Palanco, Raúl Pérez-López, Inés Galindo-Jiménez, Alberto Bernal, Sergio Aranda, María Cruz López-Escalante, Dietmar Leinen, Jose F.
