Abstract : The outbreak of COVID-19 virus, which started in Wuhan, China and is now affecting
many cities around the world, shows that in addition to analyzing and paying attention to cities as a
separate factor and element, it is necessary to change Climate In terms of air pollution and
environmental pollution in other cities and countries of the world, there should be a special look to
identify and prevent potential hazards to the city and to take appropriate and effective measures to
deal with it. Global quarantine in most countries of the world, which was carried out periodically
and is still in force, has affected most countries economically and socially, and has had a significant
impact on human life and the environment. The Corona virus pandemic has reduced global
economic activity and reduced emissions from transportation and industrial sectors. Nitrogen
dioxide (NO2) gas can be mentioned as an important and traceable gas for air pollution. Excessive
condensation of this gas in the air causes excessive air pollution. This type of gas is mainly
produced by the combustion of fossil fuels. Excessive work of light and heavy machinery in traffic
and factories causes the accumulation of this gas and causes excessive air pollution. According to
these issues, satellite science and remote sensing are used to study the level of air pollution. The
Sentinel-5 Precursor satellite is used to study and evaluate the amount of pollutant gases in the air.
The European Space Agency (ESA) and the US National Aeronautics and Space Administration
(NASA) are producing satellite images of the Sentinel-5 Precursor and the AURA satellite,
respectively, using the Tropospheric Monitor and the Ozone Monitor (TROPOMI). Collect data
(images). Due to the growth of industrial centers, factories and increasing the amount of
transportation and traffic and weather conditions that have a great impact on warming and air
pollution, for this purpose to study the polluting gases affecting the climatic conditions of the study
areas from Remote sensing using Sentinel-5 Precursor data is discussed in this paper.
