Summary: Aerosol optical depth (AOD) is a major source of solar irradiance forecast error in clear-sky conditions. Improving the accuracy of AOD in NWP models like WRF can reduce errors in direct normal irradiance (DNI) and global horizontal irradiance (GHI), thereby improving solar power forecast accuracy in cloud-free conditions. This study analyzed clear-sky GHI and DNI using different aerosol representations in the WRF-Solar model, and compared them with high-quality irradiance observations. The results showed that WRF-Solar with GEOS-5 AOD had the lowest errors in clear-sky DNI, while WRF-Solar with CAMS AOD had the highest errors. Clear-sky GHI statistics did not differ much among the four models.

Summary: This study developed and compared five high-speed and highly accurate hybrid models to simulate diffuse radiation in different regions of China. By combining multiple data sources and using various machine learning models, the proposed RTM-RF method exhibited superior performance. The uncertainty caused by the measurement errors of aerosol optical properties and land surface albedo was quantified, and the relative contributions of multiple variables to diffuse radiation were analyzed. AOD, SZA, and single-scattering albedo were found to contribute significantly more than other variables.

Summary: The renewable energy industry is expanding rapidly as a result of environmental pollution and rising prices of fossil fuels. Solar energy, which constitutes the largest proportion of renewable energy, is particularly affected by weather and climate change, making climate prediction essential. However, the Korea Meteorological Administration does not currently predict solar radiation, which is closely related to solar power, necessitating the need for solar radiation prediction technology. This study predicts solar radiation using extra-atmospheric solar radiation and three weather variables, comparing the performance of different single models in machine and deep learning.

Summary: The study found that a high-resolution coupled physical-ecosystem model simulations can resolve most of the known surface and subsurface features of the Bay of Bengal, but with differences in salinity and chlorophyll-a, and negligible differences in temperature. The modeled chlorophyll-a concentration is correlated with nutrient supply to the base of the euphotic layer and mixed layer in the Bay of Bengal.

Summary: Solar energy is a significant renewable energy source that can contribute to global energy demand. However, its intermittent nature makes it challenging to integrate into the electrical system. In this study, we compared two machine learning techniques, deep learning (DL) and support vector regression (SVR), for solar forecasting. Our testing in Spain found that DL achieved a mean absolute percentage error of 7.9%, while SVR achieved 8.52%. Although DL had the best results, it is worth mentioning that SVR also performed well.

Summary: This study assessed three machine learning models for predicting global and diffuse solar radiation in eight Chinese cities. The results showed that coastal locations had higher prediction error values compared to inland locations. The SVM model outperformed the other models in all locations, followed by GLMNET and RF. The accuracy of solar radiation prediction was closely related to weather and pollution conditions.

Summary: Using a random forest model, this study analyzed solar radiation data from seven stations in the North China Plain. The results showed that total cloud cover and aerosol optical depth were the most important factors affecting global and diffuse radiation. The study also explored the interactions between boundary layer height, aerosols, and solar radiation in urban areas. Additionally, the joint analysis revealed non-linear relationships between solar radiation and input feature pairs.
