VIAN-Climate & Environment Webinar on: “Daily PM2.5 concentration mapping and its application in Vietnam”

On the morning of October 28, 2022, the webinar on “Daily PM2.5 concentration mapping and its application in Vietnam” was held with the facilitation and presentation by Associate Professor Dr. Nguyen Thi Nhat Thanh.

This is a highly relevant topic in recent years, given the pressing issue of air pollution in Vietnam and around the world, which has adverse effects on human health, animals, and the environment.

Regular monitoring on a large scale is crucial for assessing the current status of air pollution, devising solutions, and evaluating the effectiveness of environmental policies. However, air quality monitoring stations in Vietnam are currently limited. During the seminar, Associate Professor Dr. Nguyen Thi Nhat Thanh presented an approach to estimate the PM2.5 concentration mapping from 2012 to 2020 across Vietnam, an area significantly affected by cloudy conditions This approach used a modern statistical model called the Mixed Effects Model (MEM) on a dataset that included ground-level PM2.5 measurements, satellite-integrated Aerosol Optical Depth (AOD), meteorological maps, and land use maps.

The result of this approach is the first long-term, comprehensive, and high-quality PM2.5 dataset for Vietnam. Furthermore, Associate Professor Dr. Nguyen Thi Nhat Thanh introduced the applications of these PM2.5 datasets in research and environmental and community health management activities in Vietnam.
