The total electron content perturbation (TECP) maps at E- and F-shell heights at 09:30 UT on July 3 (DOY 184), 2022. The top (a, b) and middle two subplots (c, d) show the reconstruction results using only GPS data from GEONET and multi-GNSS data from both GEONET and SoftBank, respectively. The subplots (e, h) in the rightmost display the corresponding 2-D TECP maps obtained by using the single-layer model (SLM) at 300 and 100 km altitude, respectively. Subplots (f, g) in the bottom zoom in on the perturbed regions in subplots (a) and (c), respectively
