Dear Yongha Kim, dear authors,

Thank you for submitting your manuscript to Annales Geophysicae and for your response to the referees’ comments. The study you are reporting is interesting contribution to the knowledge of the coupling of the solar wind-magnetosphere-ionosphere system over the African region. However, as you already know, the referees had some important objections to the present version of the manuscript, and this is a reason why I am suggesting a major revision. From my side, I suggest to make reference in the improved manuscript the already published paper by Okoh et al (2019) and introduce brief comparison of the approaches and finding presented in both your and Okoh’s paper. Please, consider carefully and discuss in the revised version of the manuscript all comments of the referees indicating the changes you have newly introduced. The manuscript will be revised once again.
If you are prepared to undertake the improvements required, please submit the revised manuscript.
Kindest regards

Yours sincerely
D. Buresova

Dear Dr. Yongha Kim, dear authors,

The manuscript angeo-2019-160 entitled “Modeling Total Electron Content derived from radio occultation measurements by COSMIC satellites over the African Region” has undergone the second revision. Although the manuscript still needs additional corrections and clarification of some specific points raised by opponents, I am pleased to inform you that the current status of your article is a “minor revision”.
Please, consider in the revised version of the manuscript comments and suggestions of the referees indicating the changes you have newly introduced. After you’ll send us the improved version, I’ll read it once again.
Kindest regards

Yours sincerely
D. Buresova
