Fig. 6From: Comparison of seasonal and longitudinal variation of daytime MSTID activity using GPS observation and GAIA simulationsComparison of longitudinal variation of daytime MSTID activity during the maximum occurrence period (i.e. January in northern hemisphere and July in southern hemisphere) in GPS observation (black lines) and GAIA simulation (red lines) in (left) NH (right) SH. Horizontal axis denotes longitude, and vertical axis represents the MSTID activityBack to article page
