Analysis of NO2 tropospheric column amount at airports in Malaysia before and during Covid-19 pandemic using Sentinel-5P TROPOMI data

Air pollution is a serious environmental and health issue in Malaysia due to the recent urbanization processes. The main sources of air pollutants are motorized vehicles in urban areas and airports and industrial activities. At the airports, NO2 is the main pollutant of concern besides aerosols part...
