Fengyun-4A satellite and machine learning model advance solar photovoltaic resource mapping in China

China's commitment to achieving carbon neutrality takes a significant step forward with the successful collaboration between the Institute of Atmospheric Physics, Chinese Academy of Sciences (IAP/CAS), Harbin Institute of Technology (HIT) and the National Satellite Meteorological Center (MSMC) of China Meteorological Administration. Together, they have made notable progress in solar resource assessment, a critical element for utilizing photovoltaic (PV) energy efficiently.
