About
Dr. Guannan Geng is a leading environmental scientist whose research centers on satellite-based air quality monitoring, with a particular focus on fine particulate matter (PM₂.₅) pollution in China. Her most impactful work involves pioneering the use of geostationary satellite data to estimate ground-level PM₂.₅ concentrations at an unprecedented 6 km resolution across eastern China. By leveraging aerosol optical depth (AOD) retrieved from the GOCI satellite instrument, Dr. Geng developed sophisticated statistical models that transform satellite observations into actionable air quality data. Her seminal 2015 paper on this methodology has garnered 82 citations, reflecting its foundational role in the field. This work represents a major contribution to environmental health research, enabling more precise exposure assessments for epidemiological studies and informing pollution control policies. Dr. Geng’s innovative approach bridges the gap between satellite remote sensing and public health, demonstrating how high-resolution geostationary data can overcome limitations of polar-orbiting satellites. Her achievements have established her as a key figure in satellite-based air quality science, with her methods being widely adopted by researchers studying the health impacts of air pollution across rapidly urbanizing regions.
