一个改进的理想大气太阳辐射计算模型
An Improved Daily Solar Radiation Model in Ideal Atmosphere
摘要
Abstract
In this paper we select 10 broad spectrum solar radiation mechanism models widely used in for- eign countries and achieved recognitions, and there are separate transmittance formulas in the main atmos- pheric attenuation process. The transmission (TR, To, TaM), direct radiation, and diffuse radiation by se- lected models in relation to the exact spectrum model SMARTS are compared and reviewed strictly in an i- deal atmosphere. On this basis, we then selected the model of high precision METSTAT, and corrected its defects and inadequacies regarding optical mass, transmission rate of ozone absorption and uniformly mixed gas absorption transmittance of the model, then an improved solar radiation model METSTAT_M in an i- deal atmosphere is obtained. After a rigorous comparison, it is demonstrated that the METSTAT_M mod- el is superior to other models.关键词
