Our study aims to focus on the sunlight coming to the earth and the different intensity that has a strong relationship with the number of days in the year, and therefore we have taken these values throughout the year in the city of Biskra, Algeria. Based on the information we wanted to introduce some effects, for example, some atmospheric compounds and also the angle of inclination that receives sunlight knowing that the total sunlight is composed of two direct and diffuse compounds. Our study focuses on the creation of a mathematical model that helps us to include all the effects of atmospheric compounds, which are CO2 and O3. Finally, water vapor with the angstrom factor and all these values are within the Link Air Factor and create another mathematical model that calculates the total solar radiation as a function to direct solar radiation, and diffuse solar radiation, each of which is a function in the angle of inclination and a function in the angle of elevation of the sun and also a function in the coefficient of the atmospheric Linke. Finally, satisfactory results are obtained with the least relative errors. The predicted results were remarkably close and proportional to the changes of the solar radiation with the Link’s atmospheric factor and tilt angle. The average daily global radiation in Biskra (34.8 N latitude, 5.73 E longitude) is predicted with good estimations.

一种利用林克浊度系数和倾角估算太阳辐射分布的新方法

我们的研究旨在关注到达地球的阳光以及与一年中的天数有密切关系的不同强度,因此我们在阿尔及利亚比斯克拉市全年采用这些值。基于这些信息,我们想介绍一些影响,例如,一些大气化合物以及接收阳光的倾角,知道总阳光由两种直接和漫射化合物组成。我们的研究侧重于创建一个数学模型,帮助我们将大气化合物(即 CO2 和 O3)的所有影响包括在内。最后,具有埃因数的水蒸气和所有这些值都在链接空气因数内,并创建另一个数学模型,该模型计算总太阳辐射作为直接太阳辐射的函数,和漫射太阳辐射,每一个都是倾斜角和太阳仰角的函数,也是大气林克系数的函数。最后,以最小的相对误差获得满意的结果。预测结果与太阳辐射随林克大气因子和倾斜角的变化非常接近并成正比。比斯克拉(北纬 34.8 度,东经 5.73 度)的平均每日全球辐射得到了很好的预测。预测结果与太阳辐射随林克大气因子和倾斜角的变化非常接近并成正比。比斯克拉(北纬 34.8 度,东经 5.73 度)的平均每日全球辐射得到了很好的预测。预测结果与太阳辐射随林克大气因子和倾斜角的变化非常接近并成正比。比斯克拉(北纬 34.8 度,东经 5.73 度)的平均每日全球辐射得到了很好的预测。
