“…These studies focused on the application of various VATDMs and instruments to analyze volcanic ash and SO 2 dispersal and their impact, compare satellite, ground-based, and UAV/aircraft data with numerical simulations, validate models with field data, improve volcanic ash predictions, increase the understanding of eruption dynamics, and assess the transport of volcanic aerosols over long distances. A number of VATDMs such as Numerical Atmospheric-dispersion Modelling Environment (NAME) [117,126], Modèle Lagrangien de Dispersion de Particules d'ordre zéro (MLDP0) [18], FALL3D [113,114,119,132], CMAQ [115], Hybrid Single Particle Lagrangian Integrated Trajectory (HYSPLIT) [124,125,128,135,136], PUFF [129], Massive-Parallel Trajectory Calculations (MAPTRAC) [131], VOLC-CALL PUFF [120], PlumeTraj [133], PlumeMoM [133], chemistry transport model (CHIMERE) [118,139], and Fplume [17] have been used in conjunction with MISR, MODIS, SEVIRI, IASI, OMI, VIIRS, OMPS, AIRS, ABI, and AHI satellite data, ground-based data [116,129,133,136,139], and UAV/aircraft-based remote sensing data [117].…”
