This dataset contains (1) the output of a volcanic ash transport and dispersion model (Numerical Atmospheric-dispersion Modelling Environment - NAME) simulations of the 2019 Raikoke eruption used in the UK Met Office volcanic ash source inversion system (InTEM), (2) Himawari satellite retrievals provided by kind permission of the UK Met Office that were used in InTEM inversion system, (3) output from the InTEM system for the Raikoke eruption, (4) output of volcanic ash transport and dispersion model simulations used for comparison to satellite retrievals and to produce ash hazard risk maps. The use of this data is outlined in Natalie Harvey et al. (2022): Quantifying the impact of ensemble meteorology on emission estimates and volcanic ash forecasts of the Raikoke 2019 eruption.
