The problem of air pollution is one of the main environmental factors affecting Vietnam. In this article, we evaluate the dynamics of air pollution over Hanoi, the capital of Vietnam, based on a dynamic comparison of sets of multi-level satellite data, which allows us to assess the potential of emissions. The methods of calculating the UVAI pollution assessment index, ozone monitoring (OMI), a time series of MERRA-2 reanalysis data on the concentration of black carbon (CHU) for 5 years from 2017 to 2021 were used as a basis, and pollution trends over time were studied. In addition, a comparison of the fire hazard analysis for the studied indicators was carried out. Our results highlight the need for better air pollution monitoring systems to record episodic pollution events and their impact on the surface, such as industrial incineration of garbage in selected areas.
Keywords:satellite images, air pollution, environmental indicators, cartography of the ecology of Hanoi, Vietnam.
