Since 2000, the biennial ERAD (European conference on RADar in meteorology and hydrology) conference is an awaited occasion, within the radar community, to connect academia, industry, and weather services, in an international and dynamic environment, fostering collaboration among scientists, engineers, and operational stakeholders. This journey keeps going thanks to the dedicated effort and collaboration of the international weather radar community.The Institute of Atmospheric Sciences and Climate of Italian National Research Council (CNR-ISAC) and the Sapienza University of Rome had the honour to host the 12th edition in Rome, Italy. Each ERAD conference, while sharing common goals, offers something unique that reflects the characteristics of its host venue and organizers. In Rome, we had the privilege of holding the conference on the vibrant main campus of Italy’s largest university, Sapienza University of Rome, which provided ERAD 2024 with access to the monumental Aula Magna auditorium and the fascinating Museum of Classical Art. Continuing the tradition of ERAD conferences, students and early-stage researchers had the opportunity to attend the event and trainings, present their studies, and most importantly, network within a diverse community that fosters knowledge in the areas of scientific and technological research related to radar in meteorology and other environmental applications. Some of them received support for their participation, and poster competitions and oral presentations were organized to stimulate quality research.Finally, ERAD 2024 also provided a valuable platform for scientists and weather services to interact with manufacturers to stay informed about the latest product offerings related to weather radar. As many other conferences, after the experience of COVID 19 pandemic, ERAD 2024 offered the flexibility of attendance, allowing participants to be physically present at the Sapienza venue or to join remotely. At the conference, seven keynotes were presented, including one by the winner of the Gutta Aurea award, dedicated to the late Prof. Frank S. Marzano. A total of 154 oral presentations and 217 poster presentations were delivered in sessions organized according to the following topics: – Clouds and precipitation physics– Operational aspects– Weather radar and climate– Weather Radar technologies– Radar hydrometeorological applications– Radar and society– Space borne clouds and precipitation radar We are pleased to present the collection of all the abstracts presented at the 12th edition of the European Conference on Radar in Meteorology and Hydrology.
