Energy losses of albedo electrons in the upper layers of the atmosphere in the geomagnetic field

An analysis is presented of ionizational and deceleration losses of energy experienced by albedo electrons in the nonuniform geomagnetic field as they ascend from heights of 30-60 km to 200 km. The fraction of integral energy carried to a height of 200 km by electrons produced near the equator at a height of 40 km with energies of 100-300 MeV and at a pitch angle of 89 deg is calculated. This fraction is found to be very small; hence, a direct comparison of vertical electron fluxes in the specified energy range in the stratosphere (h = 40 km) with fluxes at h = 200 km is incorrect if data on the angular and spectral characteristics of the compared fluxes is not taken into account.
