鉴于冰立方对高能天体物理中微子的观测，对大气中微子背景的不确定性进行量化是很重要的。不确定性的来源有两个，一是对产生中微子的初级宇宙射线的光谱和成分的不完全了解，二是对高能强子的产生（包括粲）的了解有限。本文是对这两个方面的概述。
In view of the observation by IceCube of high-energy astrophysical neutrinos, it is important to quantify the uncertainty in the background of atmospheric neutrinos. There are two sources of uncertainty, the imperfect knowledge of the spectrum and composition of the primary cosmic rays that produce the neutrinos and the limited understanding of hadron production, including charm, at high energy. This paper is an overview of both aspects.
