Clear sky solar irradiance models: A review of seventy models

Clear sky solar irradiance parametric models seek to simplify the atmospheric attenuation with relatively simple parameterizations in order to estimate solar irradiance under clear sky conditions, avoiding the use of computationally expensive radiative transfer models. These models are particularly useful when estimating solar irradiation with satellite retrievals. Due to the great number of clear sky parametric models, it is somehow complicated...
