Transfers of energy between the radiation belts and the atmosphere.
Questions to be addressed On-board instruments Studies to be performed

▪ Detect and characterize burst of precipitated electrons (lightning induced electron precipitation);


▪ Detect and characterize burst of accelerated electrons (runaway electron beams), investigate potential correlations with extensive atmospheric showers, evaluate the potential contributions to the radiation belts.

▪ Relativistic and energetic electrons;


▪ Wave fields from DC to 30 MHz.

▪ Detection/characterization of bursts of downcoming and upgoing energetic electrons;


▪ Correlation with ground-based measurements of extensive atmospheric showers;


▪ Comparisons with other spacecraft measurements to evaluate contributions of accelerated electrons to radiation belts.

▪ Detect and characterize electromagnetic or electrostatic emissions associated with precipitated or/and accelerated electrons. ▪ Same as above; ▪ Detection/characterization of EM emissions (characteristic frequencies) associated with bursts of upgoing and downcoming electrons.
▪ Model variations of the geographical distribution of bursts of electrons, TLEs, TGFs and associated emissions as regards to: geographical and invariant coordinates, local time, seasons, geomagnetic indices. ▪ Cameras and photometers;
▪ X- and gamma-rays;
▪ Relativistic and energetic electrons;
▪ Wave field measurements from DC to 30 MHz;
▪ 0+ whistler detector. 		▪ Statistical distribution of fluxes of electrons and wave power spectra as regards to TLEs, TGFs, 0+ whistler, and geophysical parameters.
