Solar radiation reaching the surface in China was analyzed on the basis of four data sets. National Centers for Environment Prediction (NCEP) reanalysis solar radiation data exceeded surface observations by 40 W/m 2 to more than 100 W/m 2.
Thus, understanding the long-term variations of solar radiation is important for planning the utilizations of solar energy resources over mainland China in the future. Measurement by pyranometer with accurately calibrated are the best way to obtain the long-term SSR data (Wang et al., 2012).
Conclusions and Discussion The downwelling surface solar radiation in China were studied on the basis of four data sets: NCEP reanalysis data set; surface-based observation data set from CDC/CMA and satellite estimates from GISS and UMD. Radiation data were intercompared.
Radiation data with varied spatial coverage and timescales could also influenced the results of trend analyses of SSR. The higher accuracy of the variation trend of the SSR over mainland China can be detected based on more intensive observation data.
The systematic overestimation by satellite algorithms in China was most likely associated with aerosols and their complex interactions with clouds. Surface data indicated a significant decline in solar radiation from 1961 to 1990, but the decline trend did not persist into the 1990s.
Annual and multi-year mean DSR over China with spatial resolution of 10 km for each year during 1982–2022. The mean diffuse solar radiation experienced significant turning points in 1990, 2000 and 2010, with DSR values of 75.6 W m −2, 78.8 W m −2,79.5 W m −2 respectively. However, in 2020, there was a slight decrease in the mean DSR (78.2 W m −2).
