Tropospheric ozone (O3) is an important surface pollutant in urban areas, and it has complex formation mechanisms that depend on the atmospheric chemistry and meteorological factors. The severe reductions observed in anthropogenic emissions during the COVID-19 pandemic can further our understanding of the photochemical mechanisms leading to O3 formation and provide guidance for policies aimed at reducing air pollution.
Two presentations from URBAG members have been shared in the latest EGU's annual General Assembly EGU22, hosted in Vienna, Austria. Thanks to the hybrid format, over 14,000 attendees from 116 countries have shared each work throughout the week-long conference from 23-27 May 2022.
The URBAG members worked on three presentations during the EGU 2021 conference, where 18 155 scientists from 136 different countries have met. With approximately 13 000 users per day, the conference has been considered a resounding success. The sessions have been conditioned by the global Covid-19 pandemic, forcing it to be carried out in virtual format.
