In contrast to conventional SST which parameterizes the model with non-overlapping pixel, the MST allows a decomposition of the ionosphere into a set of SSTs with different cell sizes; at each model location, the IED receives different contributions from all the MST submodels in the process of inversion. The final MST model is a post-inversion superposition of all submodels, and the final MST solution is a superposition of solutions of all submodels. In comparison with the conventional SST models, superior results of the MST are observed in a numerical simulation. A careful validation of the reliability and superiority of MST is made. According to the statistical analysis of average root mean square error, the result shows that the proposed model offers an improvement of 15% over the conventional SST models.
