Fig. 2. (a)From: A new global empirical model of the electron temperature with the inclusion of the solar activity variations for IRINormalized latitude profiles for Equinox (solid line—Te for high solar activity minus Te for low solar activity; dashed line—Te for medium solar activity minus Te for low solar activity). The numbers represent median value of PF10.7 in each latitude bin—upper row for high solar activity, middle row for medium solar activity and the bottom row for low solar activity. Note that for low solar activity the corresponding curve is zero line.Back to article page
