Earth-skimming neutrinos and Atmosphere-skimming neutrinos or cosmic rays can induce extensive air showers that present some peculiarities in comparison to the better-characterized down-going showers. For some geometries, cascades can take place high in the atmosphere and develop over several hundred of kilometers, giving ample time for the geomagnetic field to deflect the particles. For other geometries, cascades can develop very close to the ground where the density is high and the resulting cascades are very short. Development in a thinner or denser atmosphere will shift the balance between the average interaction length and decay length of particles, giving showers that can have very different hadronic/electromagnetic components with respect to regular down-going showers. In this article we will showcase ZHAireS-RASPASS, acustom-built modification to the ZHAireS suite capable of simulating Atmosphere-Skimming and up-going (from Earth-skimming) showers and their radio-emission, focusing on how it could be used to inform the design and data interpretation of balloon-borne and satellite-borne experiments
