In the context of the 4th Symposium "Ultrafine Particles in Outdoor Air and Indoor Air" (12/13.09.2022) in Berlin, Stephan Weber presented on the impact of the Corona Lockdown in spring 2020 on size-classified fluxes of ultrafine particles in Berlin. Many thanks to Wolfgang Frenzel and Andreas Held for the invitation. The results can also be read in our recent publication (Straaten et al., 2022).
