Fig. 3 Pseudosection plots of the apparent resistivity difference between original and modified models.
In d and i, light colors indicate low agreement between original and forward model projections while dark colors indicate high agreement.
This method enables the selection of reduced models based on their relative performance over the system state space of interest, by determining input trajectories that maximize error in outputs between original and reduced models.
There is no simple algebraic relationship that could be used to define mappings between original and hybrid model parameters parameters,, i = 1... n org and, m = 1... n hyb, i.e. there is no analytical function for all m that can be used to relate the original and hybrid models.
d Difference between original and MAF-2 models.
c Difference between original and MAF-1 models.
b Difference between original and PHO-1 models.
C) Pseudosection plots of apparent resistivity difference between original and PHO-2 model after adding synthetic site in the center of the island.
After investigating the correspondance between the original and hybrid model concerning single parameter perturbations of the original model, we used the hybrid model to identify combinations of parameters aimed at a specific critical effect.
Among them, the longest duration of passage through the overlapping shadows by one satellite in one day is 474 s, and the maximum difference of the same epoch between the original and refined models is 0.329.
There are no simple and direct analytical relationships between the original and simplified models.
