摘要:
为了提高对基于静止卫星FY-2G可见光通道数据反演地面入射太阳辐射产品的精度,使其与Hybrid模型计算得到的站点地面入射辐射数据进行STMAS方法融合,然后利用中国地区(2015年)91个站点的地面观测数据验证和评估融合前后产品(SWDN和SWDN\|MERGE),并与CERES卫星反演SYN1deg产品和ERA\|Interim再分析地面入射太阳辐射资料进行比较分析。结果表明:①CERES卫星反演产品与观测最接近,FY-2G卫星反演产品次之,ERA\|Interim地面入射太阳辐射产品误差最大;②FY-2G卫星反演的两套产品,SWDN\|MERGE相比于SWDN有较大改进;③从地面入射太阳辐射2015年年平均值分析,4套数据产品之间有较好的一致性,FY-2G卫星反演地面入射太阳辐射数据产品空间分辨更高,细节更清晰。以上分析结果可为4套数据产品的订正及其在中国地区的应用提供依据。

Abstract: In order to improve theprecision of downward surface solar radiation product based on the FY\|2G visible channel data of geostationary satellite,it is fused by the method of STMAS withthe downward surface solar radiationcalculated by Hybrid,examining and evaluating SWDN and SWDN\|MERGE using ground observation data (OBS) from 91 ground observation stations in China (2015),and compared with CERES satellite\|derived application and ERA\|Interim reanalysis data.The results show that:(1)CERES has the highest precision,FY\|2G follows,ERA\|Interim is the worst.(2)SWDN\|MERGE has a greater improvement than SWDN when comparing the two sets of downward surface solar radiation data derived from FY\|2G satellite.(3) There is good consistency between the four sets of data from the analysis of 2015 year average value,however the surface downward shortwave radiation data derived from FY\|2G satellite is higher in spatial resolution and sharper in details.The above results could be used as scientific evidences for revising the four sets of data and the study of climate change in China.
