[1] Morente et al. [2009b] present a numerical simulation of Titan’s electromagnetic cavity in the VLF band using the Transmission Line Matrix (TLM) method and a comprehensible analysis procedure for extracting weak resonances from a system with high losses using its late time response. Before being applied to the data sent by the Huygens probe from Titan’s atmosphere, our methodology was checked using analytical functions and the data generated by the TLM numerical simulation of Titan’s atmosphere. Grard et al. [2011] criticize our analysis procedure. In this reply, we deconstruct their arguments one by one, showing that the analysis procedure, repeatedly checked, does not generate artificial resonances and remains valid. [2] The main target of the Huygens probe, included in the cooperative NASA/ESA Cassini‐Huygens mission to the Saturn system, was to characterize in situ the properties of Titan’s atmosphere and surface. Among other physical magnitudes, the Huygens probe measured the natural electric field in Titan’s atmosphere using two electrodes of a mutual impedance probe located in Huygens’s deployable booms. The measured electric field was sampled, a discrete
