Study on the Influence of Haze on Solar Radiation:Taking Beijing as an Example
Smog can reduce the intensity of solar radiation and affect radiation transmission.This study adopts theoretical analysis and Origin quantitative fitting analysis,and takes the seasonal typical days in Beijing in 2023 as an example to determine the impact of haze on solar radiation intensity and quantitatively analyze the reduc-tion of solar radiation caused by haze,laying a foundation for reducing the impact of haze on solar radiation.The results show that the haze degree of typical days in 2023 in Beijing has the largest fluctuation,and the radiation decreases by 26.72%;the typical daily haze degree in summer fluctuated less than that in spring,but the radia-tion reduction was larger,which was 27.99%;in autumn,the haze degree fluctuated the least,but the haze had the most serious effect on solar radiation,with a reduction rate of 33.00%;typical daily haze in winter has the smallest reduction of solar radiation,only 10.00%.It shows that there are differences in macroscopic conditions such as season(temperature)and time,and the influence of haze on solar radiation intensity is also different,however,through Gaussian fitting,it is found that the two are still highly correlated.
