Global distributions of simulated TEC perturbation triggered by the Hunga-Tonga eruption on 15 January 2022 at 06 UT (a), at 07 UT (b), at 08 UT (c), at 09UT (d), at 10 UT (e), at 11 UT (f), at 12 UT (g), at 13 UT (h), and 14 UT(i). Units are TECU. A red asterisk indicates the location of the Hunga-Tonga volcano. The TEC variation is shown by taking the difference of TEC with and without the Hunga-Tonga eruption
