Parameter: Ion drift at 300 km (perpendicular to geomagnetic field)

Brief Description:
The model describes the diurnal and seasonal variation of the F-region electric-field-induced plasma drift as measured by the St. Santin (44 N, 2 E) incoherent scatter radar. It was established on the basis of three years (1973-1975) of measurements during magnetically quiet periods. The ion velocity perpendicular to the geomagnetic field is represented by a simple harmonic function in local time with nine coefficients per season.
