Archived radar data has various applications, though it is often underutilised. Nevertheless, this information has the possibility to aid in the development of accurate and relevant climate adaptation tools, inform climate-resilient urban development strategies, and numerous other personal and societal applications. Our work in the RadClim Baltic Sea Region (BSR) project established the potential features, user demand, and feasibility of developing a high-resolution radar-based precipitation climatology (RPC) in the BSR through a user needs survey. This survey was distributed to various user groups in Sweden, Estonia, and Poland in native languages to maximise participation, and revealed that a strong majority of respondents felt their work would benefit from using data provided by an RPC. Consultations with the national weather services in these countries, as well as those in Germany and Finland, the latter two countries representing the current state of the art in this field in Europe, aided in ensuring best practices were adhered to. Ongoing national work related to high-resolution radar-based datasets and tools, and the utility of the existing data across the partner countries and the BSR, in general, were also investigated.
