Lava Aerosol Gas and Trace Element data from the Fagradalsfjall 2021-2023 eruption, Iceland

Aerosol gas and trace element data collected above vents and lava flows during the 2021-2023 Fagradaslfjall volcanic eruptions, Iceland, as well as input parameters and results for thermochemical equilibrium modelling performed in the case study. The gas data includes those collected by Fourier transform infrared (FTIR) spectroscopy and mutiGAS instrument sampling. The trace element data was collected by filter pack sampling mounted on an Uncrewed Aerial Vehicle (UAV) and analysed by Ion Chromatography Mass Spectrometry (IC-MS) and Inductively coupled plasma mass spectrometry (ICP-MS). These data support the paper Wainman et al., 2024 "Trace element emissions vary with lava flow age and thermal evolution during the Fagradalsfjall 2021-2023 eruptnkedions, Iceland" which also contains a full description of sampling method (document listed below).
