Webb&Essex Model

This model was developed on the basis of Akebono satellite measurements. Average Te distributions in the altitude range 1000 to 10,000 km and in the goemagnetic latitude range +/- 70 degrees are used to construct a simple analytical model. Transitions between a constant nighttime and daytime state are modelled with cubic splines. Second order polynomials are used to represent the altitudinal profile and the polynomial coefficients are described in terms of altitude, geomagnetic latitude and local time.
