地表太阳辐照度（SSI）数据对于规划和估计太阳能发电厂的产量非常重要。监测气候变化需要长期高质量的地面太阳辐射数据。本文介绍了一种新的地面太阳辐照度数据集，即由臭氧监测仪（OMI）获得的宽波段（0.2-4 μm）地面太阳辐照度产品。OMI SSI算法基于Heliosat方法，并使用OMI O2-O2云产品作为主要输入。2008年，OMI SSI数据与全球分布的基线地面辐射网络（BSRN）在19个台站的测量结果进行了验证。此外，月平均OMI SSI数据进行了比较，独立的表面太阳辐照度产品从国际卫星云气候学项目通量数据（ISCCP-FD）和云和地球辐射能系统（CERES）的数据为2005年。OMI SSI和BSRN全局（直接+漫射）辐照度之间的平均差异为− 1.2 W m− 2（− 0.2%），均方根误差为100.1 W m− 2（18.1%），平均绝对误差为67.8 W m− 2（12.2%）。OMI SSI和BSRN全球辐照度之间的差异在大陆和沿海地区较小，在沙漠和岛屿地区较大。OMI SSI与CERES短波（SW）模式B地面向下通量（SDF）产品有很好的一致性。月平均1度网格OMI SSI与CERES SW SDF之间的相关系数和一致性指数> 0.99。OMI SSI低于CERES SW SDF，部分原因是太阳天顶角。平均而言，OMI SSI比ISCCP-FD SW地面向下通量低13.5 W m− 2（2.5%），并且每个月的相关系数和一致性指数均> 0.98。
Surface solar irradiance (SSI) data are important for planning and estimating the production of solar power plants. Long-term high quality surface solar radiation data are needed for monitoring climate change. This paper presents a new surface solar irradiance dataset, the broadband (0.2–4 μm) surface solar irradiance product derived from the Ozone Monitoring Instrument (OMI). The OMI SSI algorithm is based on the Heliosat method and uses the OMI O2–O2cloud product as main input. The OMI SSI data are validated against the globally distributed Baseline Surface Radiation Network (BSRN) measurements at 19 stations for the year 2008. Furthermore, the monthly mean OMI SSI data are compared to independent surface solar irradiance products from International Satellite Cloud Climatology Project Flux Data (ISCCP-FD) and Clouds and the Earth's Radiant Energy System (CERES) data for the year 2005. The mean difference between OMI SSI and BSRN global (direct + diffuse) irradiances is − 1.2 W m− 2(− 0.2%), the root mean square error is 100.1 W m− 2(18.1%), and the mean absolute error is 67.8 W m− 2(12.2%). The differences between OMI SSI and BSRN global irradiances are smaller over continental and coastal sites and larger over deserts and islands. OMI SSI has a good agreement with the CERES shortwave (SW) model B surface downward flux (SDF) product. The correlation coefficient and index of agreement between monthly mean 1-degree gridded OMI SSI and CERES SW SDF are > 0.99. OMI SSI is lower than CERES SW SDF which is partly due to the solar zenith angle. On average, OMI SSI is 13.5 W m− 2(2.5%) lower than the ISCCP-FD SW surface downward flux and the correlation coefficient and index of agreement are > 0.98 for every month.
