Fig. 5: Comparison of satellite retrievals with ensemble modelling of mean ice particle effective radius in the ice ring.
From: Transient ice ring observed during the 15 January 2022 eruption of Hunga volcano
Evolution of the mean ice particle effective radius over time for the ice ring for supersaturation of a 0.1 %, b 1 %, c 5 % and d 10 %. Time is calculated in minutes relative to 04:47 UTC on 15 January 2022. Black data points indicate the spatial mean and standard deviation (error bars) of satellite effective radius retrievals within the ice-ring region (region enclosed between two concentric circles of radial distances from 250 to 300 km). The black solid lines indicate the ensemble mean and standard deviation (shaded regions) of the effective radius from the model simulations that include a damped harmonic oscillator temperature perturbation. The red dashed lines represent the mean effective radius of the ensemble for runs with a constant ambient temperature (further details of the model simulations can be found in the Methods section). The plot was generated by the authors with Python 3.9.9 using the Matplotlib 3.5.1 package.
