Constructing High-Resolution (10 km) Daily Diffuse Solar Radiation ...
Diffuse solar radiation is an essential component of surface solar radiation that contributes to carbon sequestration, photovoltaic power generation, and renewable energy production in terrestrial ecosystems. We constructed a 39-year (1982–2020) daily diffuse solar radiation dataset (CHSSDR), using ERA5 and …

Effects of precipitation, cloud cover, and aerosol on the surface shortwave radiation over northwest China
In this study, the relationship of the surface shortwave radiation (SSR) with the daily precipitation intensity (DPREI), total cloud cover (TCC), and aerosol optical depth (AOD) is analyzed for the five northwestern provinces (Xinjiang, Qinghai, Gansu, Ningxia, Shaanxi) of China. It reveals the influences of the different DPREI levels and different …

Co‐Benefits of Mitigating Aerosol Pollution to Future Solar and …
Accelerating the global journey toward carbon neutrality requires countries to strengthen their emission reduction efforts and actively promote the transition to renewable energy. Solar and wind energy are two critical forms of renewable energy that are gaining increasing global attention (Y. Chen et al., 2023; Lei et al., 2023). As both …
What drives residential rooftop solar growth in China? A spatial ...
Thirdly, over the last ten years, China has greatly reduced the cost of solar PV panels (Zhu et al., 2019) and achieved grid parity (the "tipping point" at which solar generation costs the same as electricity from the grid) in every prefecture-level city by the year 2019 (Yan et al., 2019).As for RRS potential, 20 million households with self-built …
Photosynthetically active radiation and its relationship with global ...
Photosynthetically active radiation (PAR) and other solar components were observed for a period of 3 years at Wuhan, China to determine for the first time the temporal variability of PAR fraction [PAR/G (G here stands for global solar radiation)] and its dependence on different sky conditions in Central China. PAR, G and PAR/G showed …

This study improved methods to better estimate surface direct (R dir) and diffuse (R dif) solar radiation from sunshine duration in ChinaThis study identified a spurious steeper downtrend in the observed R dir in China from 1958 to 1989, implying an overestimation of global dimming; R dir decreases by −3.52 W m −2 per decade, and R …
Comparison and Selection of Solar Radiation Data for ...
Based on the measured solar radiation and power generation data of a 5.6 kW PV grid-connected system in Beijing from June of 2012 to December of 2016, the differences between the measured data and the data provided by solar energy databases are analyzed. The results show that the measured data is lower than 80–90% of the data …
