This session is devoted to basic and applied research on atmospheric processes, phenomena and impacts linking the chemical and physical states of the atmosphere. Particular interest lies in the observations and modelling of the transport, dispersion, transformation and deposition of atmospheric compounds (including air pollutants, pollen, GHGs, radionuclides and other substances naturally or accidentally released) and how they interact with the local and global climate and weather.

Within this scope, the session draws from diverse elements of atmospheric science research related to weather, atmospheric composition and climate, and includes theoretical, numerical modelling and experimental studies on scales extending from local to global, including the urban areas. Contributions on the development of observations and modelling techniques as well as on mitigation strategies varying from nature-based solutions to emission reductions also fit the scope of the session.

Targeted towards both disciplinary and interdisciplinary audiences, this session invites oral and poster contributions on topics including, but not limited to, the following:
• Feedback processes between atmospheric compounds, meteorology, and climate
• Characterization of the effect of urban planning choices and other interventions on the emissions, transport, dispersion and concentrations of atmospheric compounds
• Observations and modelling of urban meteorology including street canyon circulation, heat and mass fluxes within and over cities
• The impact of boundary layer processes on the transport and dispersion of atmospheric compounds
• Novel air pollution and atmospheric composition monitoring networks and platforms
• Air quality and transport model development using meteorological and chemical observations
• Air quality forecasting/assesment (incl. online modelling integrating chemical weather with NWP modelling) and chemical data assimilation.

The session also serves as a dissemination forum for relevant projects, including the Copernicus Atmosphere Monitoring Service (CAMS), COST Actions, WMO Global Atmosphere Watch (GAW) SAG-GURME & SAG-APP, FAIRMODE, as well as national- and European-scale consortium projects and research infrastructures.
