             abstract = "The key question on the Earths radiation belts trapped particles 
                         lies in the understanding of how solar wind drives the 
                         magnetospheric physical mechanisms changing the trapped particle 
                         populations. Corotating Interaction Regions (CIR) from Coronal 
                         Holes (CH) are predominant structures through the descending phase 
                         of the solar cycle. Some of the solar wind conditions related to 
                         CIRs are also recurrent in each rotation, so these structures may 
                         also cause a recurrent magnetospheric response to the solar wind 
                         coupling, including the inner magnetospheric parameters, in 
                         particular at the outer radiation belt dynamics. Throughout the 
                         descending phase of the solar cycle 24, we identified 46 CIRs in 
                         the period from 2016-2019. All the CIRs are isolated solar wind 
                         structures, i.e. complex solar wind structures are out of the 
                         scope of this paper. By following seven recurrences of CH 838, we 
                         identified recurrent magnetospheric auroral disturbances, besides 
                         inner magnetosphere seed population particle injection, and as a 
                         consequence, whistler-mode chorus waves are observed in a wide 
                         frequency range and in several L-shells and Magnetic Local Time. 
                         The unprecedented Van Allen Probes observation of very low 
                         frequency (VLF) waves show that for two subsequent orbits, 
                         whistler-mode chorus waves frequency bands alternates from one 
                         satellite passage to the other, being observed in several 
                         frequency ranges during the same solar wind event.. As a result, 
                         the relativistic outer radiation belt electron fluxes can be lost 
                         and enhance each time, as a function of the chorus waves power 
                         spectral density, thus the survey of outer radiation belt particle 
                         flux from several CIR events results that dropout, enhancement or 
                         no change may occur with the same likelihood (\∼ 25%) 
                         each.",
