Title

PlumeMOM model inputs and simulation results for 22/12/2018 Anak Krakatau volcanic eruption (NERC Grants NE/T002026/1, NE/T002018/1)

Abstract

The folders contain the inputs required to run numerical simulations of the Anak Krakatau eruption in 2018, including ERA wind field data, and model input files (.bak). Two sets of simulations were used. The first set of simulations were inversions (see inversion file), which allows input parameters to be estimated through application of numerical model to observations. Multiple inversions were used accounting for different amounts of water entrained at the source (Fractions of 0 - 0.25 in 0.05 intervals). The best fit input parameters were used to run the forward model (see ForwardModel folder), and the results were compared to asses those most representative of observed eruption dynamics (Sim6).

Inputs for example grainsize distributions were estimated from field analysis, and this information has been uploaded separately. Other inputs such as plume height were estimated from information in the published record. ERA5 atmospheric profiles were used throughout. The numerical model PLUME-MOM-TSM (obtained from: https://github.com/demichie/PLUME-MoM-TSM) was applied in both inversion and forward mode (please see data description for further information).
