The range of hazards posed by active volcanoes includes the emission of solid particles (tephra) and gas species, which can also be emitted around dormant volcanoes into the atmosphere. Both emitted products are then advected and diffused in the atmosphere and eventually settle onto the ground. They can cause a wide range of impacts on the environment, human health, infrastructure and, in the case of highly explosive eruptions, even on the global climate. Observations of the dynamics of tephra and volcanic gas emissions, as well as the subsequent atmospheric transport and deposition, are fundamental for mitigating their hazard and enhancing numerical modelling. Moreover, simulating such natural phenomena is complex because it requires a three-step modelling process which can be summarized as i) Numerical Weather Prediction, ii) volcanic source modelling and iii) the atmospheric dispersion itself. The numerical treatment of each of these processes is affected by uncertainties that unavoidably cascades into the subsequent steps. In this session we welcome contributions related to the observation and modelling of atmospheric transport and dispersion of tephra and volcanic gas species and their impact. In particular, we encourage studies focusing on recent advances on observational techniques and modelling approaches near active volcanoes.
