Global maps showing the locations of COSMIC RO events for which the detected scintillation level “S4max9sec” exceeded 0.3 at F-region altitudes (150–400 km) during the post-sunset hours (i.e., 19–00 LT) of 27 July 2014 (top panel), 28 July 2014, (middle panel), and 29 July 2014 (bottom panel). Also shown are the locations of the SCINDA GPS stations (diamonds) and the Sanya and BCL ionosondes (crosses). The gray points show post-sunset COSMIC RO events with scintillation levels that did not exceed 0.3 at F-region altitudes. The red rectangle highlights the Southeast Asian sector that is analyzed further in Fig. 4
