The study is devoted to the development of a satellite method for monitoring emissions of sulfur dioxide for man- made objects in the northern territories of the Krasnoyarsk region. Practical recommendations have been developed for the application of the satellite method for monitoring sulfur dioxide emissions using the example of the Norilsk industrial zone. An assessment of the state of atmospheric air for the study area in recent years.
The paper is devoted to investigation of SO2 emissions in atmospheric air using the OMI space monitoring database for the northern territories of the Krasnoyarsk region in Russia. The highest concentration of SO2 emissions was recorded in April 2019 - 41.2 DU, and the smallest in July 2019 - 0.5 DU. Actual air pollution in populated areas for the northern territories of the Krasnoyarsk Territory corresponds to a high degree of pollution, except for 2013 and 2014 when it was a moderate degree of pollution.
The study is devoted to the estimation of sulfur dioxide emissions into the atmosphere based on satellite monitoring data in the area of the Norilsk industrial zone from 2010 to 2018. According to the measurements of the Ozone Monitoring Instrument - AURA satellite the NASA database is used. The maximum sulfur dioxide emissions amounted to 95 kt/month in November 2016, and the minimum - 0.185 kt/month in August 2011. The largest share of emissions is in January-May and November (90%). Comparison of the data obtained by the satellite method with the ground method revealed a difference of 30 to 65%, and with the method using aircraft carrier by 14 percent.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
