Fig. 8.From: A new global empirical model of the electron temperature with the inclusion of the solar activity variations for IRIPredictions of three models (New Te model, IRI Te model IK option and IRI Te model Brace and Theis option) versus data points for all points in low latitudes (−15° < invdip < 15°) in our database. Values of corr represent the linear Paerson correlation coefficient of calculated model and measured data vectors.Back to article page
