Summary

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).
