Fig. 1From: Three-dimensional electron density along the WSA and MSNA latitudes probed by FORMOSAT-3/COSMICDiurnal variations of F3/C N maps at 300-km altitude at various global fixed local times in the 4 months in the Southern Hemisphere. The electron density is standardized and the colorbar range from 10 to 90 % of the electron density at each time-point plot individually. White arrows are the magnetic meridional effect U and white circle-dots are the longitudinal maximum upward effect W M at 75° S geographic, respectivelyBack to article page
