It was found that since 2011 the number and intensity of such situations has increased. On the example of smog on January 13-14, 2022 it is shown that a significant increase in the concentrations of atmospheric aerosol and equivalent of black carbon develops with temperature inversion and with a wind regime close to calm. There is an increase in both the submicron and coarse particle fractions, but more intense in the range of the submicron fraction. The formation of smog is accompanied by a decrease in the ability of aerosol particles to absorb moisture.","PeriodicalId":217776,"journal":{"name":"Atmospheric and Ocean Optics","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121320050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The GPP is crucial element for understanding land-atmosphere carbon exchange. In recent years, solar-induced chlorophyll fluorescence (SIF) observed by satellite radiometers has been considered as a new approach to advance research on monitoring of GPP from space. In this paper we presents quantitative estimates of the terrestrial gross primary production for the region of the south of Western Siberia (50º-55 º N, 75º -90º E) obtained using “sun-induced chlorophyll fluorescence” data products from orbital carbon observatories OCO-2 and OCO-3. The analysis of OCO-2 data was carried out for the period 2014-2021, the results of OCO-3 were added to processing from 2019. It was established that GPP reaches a maximum in the summer months and is ~10 − 12 gC m-2day-1.","PeriodicalId":217776,"journal":{"name":"Atmospheric and Ocean Optics","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114833345","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Annual and seasonally dependent estimates of long-term trends and interannual variations of the species under the influence of circulation factors and oscillations in t solar activity are obtained. The differences and common features of the temporal evolution of NO2 and O3 have been revealed. The important role of atmospheric circulation in long-term and interannual changes in the species contents is noted. The obtained estimates of linear trends are compared with the trends of the total NO2 and O3 content in other regions.
