利用Ångström-Prescott(A-P)太阳辐射气候学公式和山东122个国家级气象观测站的日照时数资料,估算得到全省站点的日太阳总辐射,与订正系统偏差后的欧洲中期天气预报中心ERA5数据和葵花8卫星太阳总辐射产品进行误差对比,讨论不同数据在山东空间分布上的差异.结果表明:(1)葵花8卫星订正后的太阳总辐射与观测的误差最小,在不同天气条件下表现稳定;A-P公式估算的太阳总辐射与观测的误差和ERA5数据与观测的误差接近,云量越多这两种数据的误差越大,A-P公式估算值在晴天表现较好,ERA5数据在多云天表现较好.(2)相比于葵花8卫星的太阳总辐射分布,A-P公式估算值在山东西部偏低,夏季在全省范围内普遍偏低;而ERA5太阳总辐射往往在低值区偏高、在高值区偏低,另外在威海数值明显偏高.(3)对山东太阳总辐射而言,葵花8卫星数据的准确性最高.
Comparative analysis of total solar radiation in Shandong based on multi-source data
Based on the Ångström-Prescott(A-P)equation and sunshine duration data of 122 national meteorological observation stations in Shandong,the daily total solar radiation is estimated,and the error and spatial differences in Shandong are discussed by comparing it with ECMWF(European Centre for Medium-Range Weather Forecasts)Reanalysis v5(ERA5)data and Himawari-8 satellite radiation product after system deviation correction.The results are as follows.(1)The corrected total solar radiation of Himawari-8 satellite has the smallest error with the observations,and the error is stable under different weather conditions.The error between the total solar radiation estimated by the A-P equation and the observations is close to that between ERA5 and the observations,and the error of the two sets of data is larger as more cloud covers.The A-P equation estimate performs well on sunny days,while ERA5 data performs well on cloudy days.(2)Compared with the total solar radiation distribution of Himawari-8 satellite,the A-P equation estimate is mainly lower in the west of Shandong,and generally lower in the whole province in summer.The total solar radiation of ERA5 data is usually higher in the low-value area and lower in the high-value area,and it is obviously higher in Weihai.(3)For the total solar radiation in Shandong,the accuracy of Himawari-8 satellite data is the highest.
