用空气质量指数修正方法计算太阳日总辐射

Calculating Total Solar Daily Radiation by Air Quality Index Correction

大气污染特别是气溶胶粒子会对太阳辐射造成影响,在建立辐射模型时应考虑空气污染的影响。通过重庆2017年的实测辐射数据分析,发现空气质量指数(AQI)与太阳日总辐射具有较强的相关性,因此,引入空气质量指数对太阳日总辐射计算模型进行修正,将其与DSRM-C模型对比,并使用2016年的数据验证。结果表明,使用空气污染指数修正的DSRM-A模型的RMSE更小,模拟效果更好。

Air pollution,especially aerosol particles,can affect solar radiation.Therefore,the impact of air pollution should be considered when building a radiation model.Through the analysis of the actual measured radiation data in Chongqing in 2017,it is found that the air quality index(AQI)has a strong correlation with the total solar daily radiation.Therefore,the air quality index is introduced to correct the existing solar daily total radiation calculation model.Comparing with the existing DSRM-C model and verifying the model with data in W2016,the results show that the RMSE of the DSRM-A model corrected with the air pollution index is smaller and the simulation effect is better.
