Electronic Density at 600 Km of Altitude. Comparison of the Measurements of the Hinotori Satellite and the Predictions of the Nequick2 Model.

Abstract

In the present work the performance of the ionospheric model NeQuick2 to predict the values of free electron density (Ne) at 600 km of height, in a period of high solar activity and for the geomagnetic latitudes -15 °, 0 ° and + 15 °, which correspond to the fringe of the equatorial anomaly, was analyzed.
The predictions of the model, were compared with data of measurements of Ne, obtained by the Japanese satellite Hinotori, from February of 1981 to June of 1982.
Only records with values of F10.7 between 63 and 193 were considered to follow recommendations of the ITU included in the NeQuick2 model, which left a total of more than 450 thousand records to analyze.
The results obtained in this work suggest the need to carry out additional studies that lead to a better representation of the Ne topside profile given by the model.
