Solar energy generation depends on weather conditions, and energy input experiences strong and frequent fluctuations. Surface solar irradiance nowcasting (0–3 h) is an effective way to overcome the intermittency of solar energy and to ensure the safe operation of grid-connected solar power plants.
Using the existing Fengyun-4A satellite and its abundant weather data, scientists from the Institute of Atmospheric Physics (IAP) of…
