Integration and Evaluation of Multi-source Meteorological Radiation Data over Qinghai-Xizang Plateau

Based on multi-source of radiation observations from CMA operational， Qinghai-Xizang Plateau Atmospheric Scientific Experiment and Chinese Academy of Sciences field stations， the integrated of multi-source radiation data over Qinghai-Xizang Plateau（IRDQTP）since 1993 has been constructed through quality control， splicing and integration.The percent of each radiation element actual records is more than 99.4%.The accuracy rate of photosynthetic effective radiation is less than 76%， and other elements are more than 96.7%.The correlation coefficient of downward shortwave radiation between atmospheric scientific experiment and meteorological operational observations at the same or similar sites exceeds 0.88.The Mbias （RMSE） of Ali （the same station site） between operational and experimental observations is -0.006 （0.141） MJ·m-2·h-1， with 99.8% distributes between -1.0 and 1.0 MJ·m-2·h-1， and Naqu （similar station site） is -0.028 （0.615） MJ·m-2·h-1， with 84.6% distributes between -1.0 and 1.0 MJ·m-2·h-1.The differen
