WMO publishes first Air Quality and Climate Bulletin - TROPOS researchers contribute with GAW aerosol data

On 3 September 2021, the World Meteorological Organization (WMO) published it’s first-ever WMO Air Quality And Climate Bulletin. The bulletin highlights the main factors that influence air quality patterns in 2020, in comparison to other years: wild fires, dust storms and COVID-19 economic turndown. While human-caused emissions of air pollutants fell during the COVID-19 economic turndown, meteorological extremes fuelled by climate and environmental change triggered unprecedented sand and dust storms and wildfires that affected air quality. This trend is continuing in 2021. Devastating wildfires in North America, Europe and Siberia have affected air quality for millions, and sand and dust storms have blanketed many regions and travelled across continents.


Part of the "WMO Air Quality And Climate Bulletin" is also an aerosol analysis of Global Atmosphere Watch (GAW) by an international group of scientists - including 4 members of TROPOS aerosol group (A. Wiedensohler, Maik Merkel, Thomas Tuch, Kay Weinhold). Data from Saxony have been disproportionately included in this analysis due to the long-standing cooperation between LfULG and TROPOS. The stations evaluated include, for example, Annaberg-Buchholz, Deutschneudorf, Dresden-Nord, Dresden-Winckelmannstrasse, Leipzig-Eisenbahnstrasse, Leipzig-Mitte, Leipzig-TROPOS and Melpitz.
