METHOD AND APPARATUS FOR PROVIDING ONELAYER SOLAR RADIATION MODEL FOR CALCULATION OF INSOLATION

摘要

PURPOSE: A configuration method of a single layer solar radiation model and a device thereof for calculating the amount of solar radiation which reaches the surface of the earth are provided to calculate the amount of solar radiation which reaches the surface of the earth based on information of absorption gas, aerosols, and clouds in atmosphere. CONSTITUTION: A direct solar radiation quantity calculation unit(210) calculates quantity of direct solar radiation of a selected point by using the eccentricity of the earth and a penetration ratio of gas based on extraterrestrial radiation and the sun. A scattering solar radiation quantity calculation unit(220) calculates the final quantity of scattering solar radiation of the selected point by using quantity of multiple scattering solar radiation, quantity of scattering solar radiation of air molecules, quantity of scattering solar radiation of aerosols. A solar radiation quantity accumulation unit(230) accumulates the quantity of direct solar radiation and the final quantity of scattering solar radiation for a fixed wavelength area.
