Summary: The study finds that higher sunshine is associated with a greater probability of discouragement among borrowing firms, particularly in low latitude zones. The authors argue that this is due to the negative mood created by abundant sunshine in hot regions. They also find that managerial features play a role in moderating the discouraging impact of sunshine.

Summary: The study found a trend of solar dimming in the Hangzhou region from 1987 to 2016, with significant differences in sunshine duration changes between urban, suburban, and rural stations. Urbanization effects, especially in the period of 2002-2016, were evident on sunshine duration trends, indicating the need to consider urbanization impacts when analyzing regional solar radiation trends.

Summary: This study compares sunshine duration-based models with other meteorological parameter-based models and develops new forecasting models. The results show that models based on other meteorological parameters have better predictions, and the newly proposed models provide more accurate estimates of global solar radiation at different locations.

Summary: This study used long-term satellite data and climate factors to analyze the start of growing season (SOS) of natural rubber in tropical areas. The study found that preseason sunshine duration had the greatest impact on SOS, and SOS had a significant delay with the increase of latitude.

Summary: The study found a dimming effect on surface solar irradiation in Sao Paulo between 1961 and the early 1980s, with no brightening effect observed. There was an increasing trend in cloud cover fraction and surface downward irradiation, while sunshine duration and diurnal temperature range showed decreasing trends.

Summary: This study shows that SunDu-derived R-s is more accurate than direct observed R-s and satellite R-s products at monthly or longer time scales. The three AVHRR-based satellite R-s products have significant biases in quantifying the trend of R-s due to inhomogeneity in satellite cloud products and lack of information on atmospheric aerosol optical depth. Adjusting the inhomogeneity, a geographically weighted regression fusion method (HGWR) merges ISCCP-HXG R-s with SunDu-derived R-s to produce a high-resolution R-s product over China from 1983 to 2017 with similar trends to SunDu-derived R-s.

Summary: Accurate forecasting of daily global solar radiation (Rs) is important for photovoltaic power and other sectors. A novel sunshine duration converting method (n_new) based on forecasted temperature and weather types data was proposed and validated. The Rs_n new model showed better accuracy than the Rs_n com model and Rs_T model, with increased correlation coefficients (R) and index of agreement (dIA) and decreased root mean squared error (RMSE) for the 1-7 days lead time over 86 sites. The Rs_n new model is recommended for short-term daily Rs forecasting.

Summary: This study focuses on analyzing the temporal and spatial trends of sunshine duration in Poland from 1971-2018, showing significant differences between seasons and regions. The longest sunshine duration occurs in July, while the shortest is in December, with variations based on latitude. The study also reveals a correlation between sunshine duration and pressure systems, cloud cover, and atmospheric optical depth.

Summary: By combining SunDu, satellite cloud fraction, and AOD data, this study generated high-spatial-resolution Rs over China from 2000 to 2017, with geographically weighted regression (GWR) showing better performance. The study found that incorporating satellite cloud fraction and AOD data into GWR can produce reliable long-term Rs variations based on SunDu-derived data.

Summary: Accurate prediction of photovoltaic power generation is achieved by establishing a functional relationship between output power and irradiation intensity. Prediction models and databases are used to estimate photovoltaic power generation based on peak sunshine hours and sunshine duration. The study found that the prediction model is highly accurate on sunny days but less accurate on rainy days due to weak solar radiation intensity.

Summary: The amount of sunlight received by plants is influenced by cloudiness and pollution. Changes in cloud cover and aerosol concentrations will impact photosynthesis and terrestrial ecosystem productivity. Research has shown that clouds and aerosols can alter the spectral composition of incoming solar radiation, thus affecting the process of photosynthesis in plants.

Summary: This paper compares the daily sunshine duration measured by different instruments and finds that the differences between manual and automatic measurements are mostly within the range of -1.0 to +1.0 hours. The annual average daily differences between different locations range from 0.3 to 0.5 hours, and regression equations are established to estimate daily sunshine duration under different sky conditions.
