“…Інформація з Sentinel-5P дозволила з високою надійністю виявляти джерела викидів забруднюючих речовин у віддалених регіонах [3]. Тому висока просторова роздільна здатність TROPOMI стала однією з головних його переваг і зумовила створення цілої низки сервісів та додатків [4,5].…”

The study describes methods for operative monitoring of atmospheric air quality over the territory of Ukraine using the Sentinel-5P satellite data. The methods provide possibility for data specification over the cities. The data processing is fully automatic and deals with the column data of nitrogen dioxide (NO2), carbon monoxide (CO), formaldehyde (HCHO), sulfur dioxide (SO2) and total ozone (O3). The system works every day and starts processing approximately 3 hours after the scanning of Ukrainian territory. The paper describes the procedure of files creation which represents the third level of data archiving. There are implemented the procedures of the adjusting to regular grids and the filtering of statistically unreliable data. The methods for data specification are developed which allow to analyze the content of chemical compounds over the cities. The paper discusses the main features for the interpretation of chemicals’ spatio-temporal distribution. It is emphasized the typical reasons for false interpretation and mistaken conclusions about atmospheric air quality while analyzing the satellite observations.

Due to COVID-19, which is a type of pneumonia produced by a coronavirus family virus, the Peruvian government has decreed mandatory social isolation. This isolation is extended until 26 April 2020. Due to this situation, people must stay at home and only go out to make purchases to cover basic needs. This situation, between other things, probably causes pollution reduction that is important for our ecosystem. In Peru, there is not a measurable way to quantify the impact of social isolation on air pollution. The present work aims to show more objectively how much decrease the aerosol pollution in Peru. For this purpose, one uses remote sensing data from Copernicus Data Hub of the European Space Agency, specifically, Sentinel-5 Precursor satellite. The results show an essential reduction of aerosol pollution in different regions of Peru, especially in Lima and the Amazon regions.

“…Recent literature has shown that measurements of TROPOMI are quite well associated with actual ground measurements of air pollutants (Lorente et al 2019 ; Griffin et al 2019 ). Zeng et al ( 2019 ) also calibrated a selection of TROPOMI product at a global scale with independent pollution measurements from NASA similar sensors. The TROPOMI Monitoring Instrument is a passive sun backscatter imaging spectrometer that allows for the acquisitions of 8-band imagery at higher spatial resolution than the predecessors.…”
