The radio upgrade, which is part of the AugerPrime upgrade, is a very important part of the future research of the Pierre Auger Observatory by adding array-based composition sensitivity for large zenith angles, for which the scintillator upgrade is not effective. Having good composition-sensitive information up to very large zenith angles is crucial for composition-improved anisotropy studies and adds to the overall aperture of the observatory.
