                         belt is observed after of the Coronal Mass Ejection (CME) reach 
                         the Earths magnetosphere on July 19, 2016. The solar wind 
                         parameters confirm the strong perturbation on the interplanetary 
                         medium, which was followed by excitation of waves over a wide 
                         range of frequencies. The Ultra Low Frequency (ULF) waves activity 
                         was detected on the ground (CARISMA magnetometer network) and on 
                         the magnetosphere (Van Allen Probes fluxgate magnetometers). The 
                         Power Spectral Density (PSD) associated with ULF waves was 
                         calculated from both ground and in situ instruments during the 
                         event. Results show that the ULF waves activity was strong at the 
                         beginning of July 20. The efficiency of the ULF wave-particle 
                         interaction in the radial diffusion is investigated by means of 
                         DLL calculation through the rapid dropout. The CARISMA Network 
                         magnetometer spread from L 7 to L 4 in a roughly constant magnetic 
                         local time meridian, in such a way that we verify the efficiency 
                         of ULF waves-particle interaction as a function of L-shell, 
                         besides the geomagnetic activity. Thereby, we investigate the role 
                         of ULF radial diffusion to different L* using an empirical model. 
                         According to the satellite measurements, compressional and 
                         poloidal polarization modes are preferential during this dropout, 
                         which may contribute significantly with the loss of particles to 
                         outer magnetosphere.",
