Magnetic data set used in the paper "Volcanomagnetic signals before and during the 2021 volcanic eruption at the Cumbre Vieja rift (La Palma, Canary Islands)"

These files contain the total intensity of the geomagnetic field (F) in nT at the three stations (CFU, SAN and GAR) deployed in La Palma in the framework of the research projects PID2019-104726GB-I00 of the Spanish Research Agency, and CSIC-LAPALMA-07 of the Spanish Ministry of Science and Innovation.

The file format is ASCII (CSV). The name of the station and the time interval are indicated in the file name. Data are organized in four columns, preceded by a header in the first row of the file: date, hour (from 1 to 24), day of the year (fractional, from 1 to 365), F (hourly mean value, in nT).

These datasets have been used in the paper "VOLCANOMAGNETIC SIGNALS BEFORE AND DURING THE 2021 VOLCANIC ERUPTION AT THE CUMBRE VIEJA RIFT (LA PALMA, CANARY ISLANDS)", by Isabel Blanco-Montenegro, Jose Arnoso, Nieves Sánchez, Fuensanta G. Montesinos, Iacopo Nicolosi, Emilio Vélez and Maite Benavent, Published in Journal of Volcanology and Geothermal Research, 455, 108200, 2024, https://doi.org/10.1016/j.jvolgeores.2024.108200.
