Additional information for "Ash Fingers Modify Tephra Sedimentation During a Coarse-Ash-Dominated Eruption: Evidence from the 23 July 2024 Etna Paroxysm"

This repository contains the datasets used and generated in support of the study. The files provides the measurements, processed datasets and derived parameters used throughout the analyses presented in the manuscript. This repository is intended to facilitate the reproducibility and reuse of the data and analyses presented in this study. Contents: Plume height measurements.xlsx Time series of volcanic plume height measurements obtained using the PlumeTraP software from 06:39 to 10:00 LT during the 23 July 2024 Etna paroxysm. MER measurements.xlsx Mass Eruption Rate (MER) estimates calculated from the plume height measurements using the methodology described in the manuscript. OPC data.xlsx Optical Particle Counter (OPC) measurements of atmospheric particulate matter concentrations (PM1, PM2.5, and PM10) collected during the 23-minute measurement interval of 08:07 to 08:30 LT. LPM data. xlsx Laser Precipitation Monitor (LPM) data collected at sampling location L1, including the time resolved grain size distribution (GSD) and the individual particle measurements including the particle’s size and fall velocity. GSD C-samples.xlsx Grain size distribution (GSD) data for the tephra samples or C-samples collected along the dispersal axis immediately after the paroxysmal episode of the 23 July 2024 paroxysmal episode. Density measurements.xlsx Particle density measurements obtained by water pycnometry using tephra samples collected during the 23 July 2024 Etna paroxysm. The spreadsheet includes the raw measurements and the calculated representative particle density adopted in the settling velocity calculations. Particle shape analysis.zip Particle shape analyses used to determine the morphology parameters adopted in the settling velocity calculations (e.g., sphericity). The folder includes the original and processed binary images, as well as the corresponding analysis results from thin-section image analysis and BetterSizer dynamic image analysis (DIA) of tephra particles.
