6. Efficiency of SPLA: Observational Validation
SPLA is validated by computing ionospheric perturbations from GPS observations carried out during the two different geophysical events, viz. (i) 26th December 2004 Sumatra-Andaman Tsunami, and (ii) 25th April 2015 Nepal-Gorkha earthquake. The perturbations occurred during these events were also computed using residual, and differential methods for comparison. Efficiency of SPLA in removing the aliases is validated by comparing the normalized rTEC, and dTEC with gROT, and by computing the magnitude of aliasing.
