About

Fengjie Zheng is a leading researcher in satellite-based aerosol remote sensing, with a focus on improving the accuracy of aerosol optical depth (AOD) retrievals over East Asia. Their work is central to understanding how atmospheric particles affect climate and air quality. Zheng’s most impactful contribution is a novel algorithm for retrieving AOD from Himawari-8/AHI data, which uses six region-specific aerosol models derived from long-term ground observations in East Asia—a paper that has garnered 73 citations. They further advanced the field by critically assessing the OMI near-UV aerosol product over Central and East Asia (46 citations), identifying key improvements and limitations in the operational algorithm. More recently, Zheng tested the retrieval capability of the FY-4A/AGRI sensor using the NNAeroG model, demonstrating the potential of China’s new-generation geostationary satellite for continuous aerosol monitoring. Their research also includes pioneering work on classifying aerosol types in Beijing using fuzzy clustering of optical and microphysical properties from AERONET sites. Through these studies, Zheng has significantly enhanced our ability to monitor aerosols from space, providing essential data for climate modeling and environmental policy.
