摘要: 提出一种非均质大气模型,推导得到不同海拔的地表或任意大气层高度的太阳辐射计算公式.通过分析将大气层视为水平的假设对太阳辐射计算带来的误差,推导得到减少这种误差的修正公式,并指出天顶角小于75°时,这种误差可忽略.1 d内海平面的太阳辐照度实测数据和此模型的计算数据基本相差不到5%,不同海拔的实测数据和此模型的计算数据也基本相差不到5%,验证了提出的非均质大气模型.

Abstract: An inhomogeneous atmosphere model was proposed to derive formulas which can be used to calculate single-wavelength solar radiation and solar irradiance at any height, from the Earths surface to various levels of the atmosphere. Besides, the error from ignoring the curvature of the atmosphere was considered, and a correction method was given to reduce it. The validation results show that calculated values are closely consistent with measured data.

Key words: spectral distribution, solar irradiance, Beers law, altitude, inhomogeneous atmosphere model
