Fig. 5

Geographic distribution of daytime scintillation events (S4 index) at different levels measured at all GPS satellites observed at UKM and Langkawi from January to December 2011 over Malaysia. The levels of scintillation intensity at UKM are coded for S4 ≥ 0.2 (green), S4 ≥ 0.3 (yellow), and S4 ≥ 0.4 (red), while those at Langkawi are coded as S4 ≥ 0.2 (blue), S4 ≥ 0.3 (magenta), and S4 ≥ 0.4 (dark red). The red dashed line shows the location of the magnetic dip equator. The contour plots of I are also displayed
