Model calculations of TEC over europe during 11 August 1999 solar eclipse Original Research Article

In this paper we presented the model calculation results of the total electron (TEC) over Europe sector obtained with using the Global Self-Consistent Model of the Thermosphere, Ionosphere and protonosphere (GSM TIP) during August 11, 1999 Solar Eclipse. The model was developed in WD of IZMIRAN and describes the three-dimensional time-dependent distribution of the upper atmosphere parameters between 80km to 15 Earthʹs radii including electron concentration. The numerical model results of the TEC calculation have been compared with the experimental data of TEC obtained with GPS measurements on the European station located near far from the path of totality. Model results have shown substantial decreasing of TEC (25–30%) with time delay about 30 min. Comparison with experimental TEC data show a reasonable agreement for a number of station such as Hers, Graz, Lamkowko, Sofia, Ankara etc. though there are some differences in the details.
