Abstract

Extremely high energy neutrinos are attenuated by the materials surrounding the neutrino detector. Topography data can provides spatial distribution of material and become an essential factor in high energy neutrino experiment, especially for the ultra high energy neutrinos. This study introduced the Antarctica topography data, including composite layers of rock, ice, and water, to investigate the topography effect neutrino events from near horizon. Azimuthal asymmetry were observed due different depth of materials along the neutrino trajectories from different direction. This model can be applied to different neutrino experiment (balloon borne detector, ground-level detector, and underground detector) to produce realistic estimation of the neutrino induced events under different geometry of detectors.
