This study examines weather data from the Murzuq meteorological station, focusing on solar radiation components such as global horizontal, direct normal, sky-diffuse, and ground-reflected radiation. The research spans nine months and employs mathematical models to compare measured and calculated values. Key findings include an updated albedo value for the region and recommendations for improving meteorological data collection to support renewable energy projects.

The article highlights the station’s critical role in providing accurate climatic data for solar energy assessments, particularly for southern Libya’s renewable energy potential. Recommendations include establishing additional meteorological stations, enhancing data accuracy, and developing a centralized database for solar radiation data.
