POPGIS – An Application Service for Air Pollution Management and Analysis in Vietnam

Fine particulate matter (PM
2.5
) pollution is a serious problem in Vietnam, especially in mega-cities such as Hanoi or Ho Chi Minh City. High levels of PM
2.5
concentration have negative impacts on public health even if the exposure is short-term. New advancements in satellite observations can capture a lot of detailed information on air quality. Via proper processing methods, those satellite observations can produce high quality PM
2.5
concentration maps that facilitates PM
2.5
impact assessment and mitigation measures at national and local scales. In this paper, we present an application service, called Pollution Observation Platform on GIS, or POPGIS, that collects inputs from multiple satellite data sources and applies new research techniques in satellite-based PM
2.5
concentration estimation and presents near real-time results to users. The system is also designed for data sharing and can be used for analysis and re-evaluation of PM
2.5
distribution maps.
