摘要

本文提出了一种新的简化技术，用于估计沿地球-空间路径低仰角的气体吸收，同时考虑了地球曲率和折射的影响。空气的折射率被模拟成与高度有关的负指数。用拉普拉斯方法对气体吸收的积分表示进行渐近展开。

Simplified method for estimating gaseous absorption at low elevation angles along earth-space paths

This paper presents a new simplified technique for estimating gaseous absorption at low elevation angles along Earth-space paths, taking into account both the effects of the Earth's curvature and refraction. The refractive index of air is modeled as a negative exponential with respect to height. Gaseous absorption is evaluated by asymptotic expansion of its integral representation using Laplace's method.
