Cross-correlation between day-to-day variability of OLR cloud-top temperature T bb and GPS scintillation index S4 observed at Kototabang (0.2 S, 100.8 E). This figure is taken from Fig. 3 of Ogawa et al. (2009). The observation period is March and April 2003. The red star () indicates the location of Kototabang, where GPS scintillation measurements were performed. The circle around the red star shows the relevant area of S4. T bb data are taken hourly, and the correlation is obtained for each hour. Local time at Kototabang is 7 h ahead of UT. “A” and “B” indicate high positive and negative enhancement of correlation coefficients, respectively
