Satellite based estimates of solar irradiance at the earth's surface—I. Modelling approaches

Renewable Energy, 1993, vol. 3, issue 4, 381-393

Abstract: Various approaches to the calculation of solar radiation at the earth's surface using satellite data are reviewed. The methods range from qualitative and subjective use of hard copy satellite images at low spatial and temporal resolution to the use of high resolution digital data and spectral radiative transfer models. Operational techniques are also described. These can be either statistically or theoretically based with varying degrees of numerical complexity. The nature of the input data requirements also varies. Some methods use widely available hard copy satellite images while others are based on digital data. There is also a wide variation in the requirements for additional environmental data. Some models meet all such requirements by analysis of the satellite data. Other models need such information as precipitable water derived from upper air soundings or empirical calculations.
