SNR and S4 plots of two 50 Hz Spire’s GNSS RO profiles highlighted in Figure 6a that are discussed as examples of a disturbed event on 2022-08-17 at 20:56 UTC. These profiles, Spr1 and Spr2, have the same Tx: GPS PRN23, but different Rxs: S135 and S127, respectively. The segment of the profile enclosed between the green dashed lines is later used for comparison with the COSMIC-2 data shown in Figure 8.
