Complete and accurate global solar radiation (R s) data at a specific region are crucial for regional climate assessment and crop growth modeling.The objective of this paper was to evaluate the capability of 12 solar radiation models based on meteorological data obtained from 21 meteorological stations in China.
On the whole, the radiation transfer model yields more accurate estimations than the FY-2C satellite global radiation data in 2008, which suggests that the solar radiation model might be more appropriate for the study of global radiation estimation in China.
Yang et al. ( 2006) had estimated solar radiation in seven stations under different climate regimes in China. In their work, except the ozone thickness, which was the satellite product, other input parameters such as sunshine duration, air temperature, and relative humidity were all the routine meteorological observations.
We used data acquired between 2001 and 2016 from 98 solar radiation measurement stations in China to verify two satellite-derived products (SARAH-E and CERES-SYN1deg) and two reanalysis data sets (ERA5 and MERRA-2).
There are 98 (17 stations with Hb) stations currently measure solar radiation after updating measurement devices . Data from the 98 surface meteorological stations across China were acquired from the National Meteorological Information Center, China Meteorological Administration.
Nine solar radiation zones are identified based on the S / S0 values for 1042 surface meteorological stations in China. Solar radiation zoning based on the S / S0 criterion is reasonable and appropriate considering the topography and general solar climate, and it is beneficial for establishing H models.
Figures 9 a and 9 b show that the annual average DGSR ranges from 6 to 26 MJ/m 2, with a national-average value of 15.55 MJ/m 2 during 2013–2014. Spatial differences are evident across China, indicating that the solar radiation intensity in northern China (western China) is higher than that in southern China (eastern China).

Nine solar radiation zones classify based on S / S0 at 1042 stations in China. Zone models develop with good accuracy. Daily global solar radiation is an indispensable variable in developing typical meteorological year and its data are important for constructing energy-efficient buildings.
Akpootu et al. (2019) evaluated the model and found that exponential and linear exponential models were more suitable for estimating global solar radiation. Nadjem et al. (2020) study found that the best model for estimating global solar radiation in southwestern Algeria was a linear exponential model.

The data set contains daily mean global solar radiation, diffuse solar radiation, and horizontal direct solar radiation from 130 stations (including replacement stations) in mainland China from May 1957. However, the radiation instruments were updated around 1993, and some stations subsequently stopped measuring DGSR. Currently, only 97 ...
