On the elaboration of wave models for the modeling of radiation belts
Abstract
Operational wave models need to be developed for the modeling of electron accelerations and losses within the plasmasphere and at the outer boundary of the plasmapause. For each type of involved emissions, they must specify the wave amplitude spectral density and the wave normal distributions as regards to the geophysical parameters at the point of observation (L, MLAT, MLT) and to the level of geomagnetic activity. Results obtained from a first version of wave models (Andre et al., Annales Geophysicae, 2002, to be published) are used to point out the miss of wave data presently available and the needs for future magnetospheric missions. Problems set by the determination of analytical expressions for the wave amplitude spectral density and the wave normal directions are discussed.
