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
