Satellite Observation Based Air Quality Study

It is indeed important to use satellite observations in air quality research, as they provide a global perspective on the distribution and transport of air pollutants. Among the most widely used satellites for air quality research such as the Ozone Monitoring Instrument (OMI) and the Moderate Resolution Imaging Spectro-radiometer (MODIS) can measure various air pollutants such as aerosols, O-3, NO2, SO2, and atmospheric gases. Satellite observations can help identify areas of severe air pollution and track changes in air quality over time and space, which can inform policy decisions and help develop effective strategies to reduce air pollution and protect public health. With the recent successive launch plans of domestic satellites such as Geostationary Korea Multi-Purpose Satellite-2A and 2B, its use in the air quality field is expected to increase. However, it is important to note that a more complete understanding of air quality issues requires qualitative and quantitative multidimensional interpretation of the data in conjunction with other means, including ground-based monitoring and forecast modelling.
