The ACTRIS user strategy is an approach to engage and serve the needs of a large community of users from the scientific domain, the private sector, and the general public, and to provide them with high- quality, integrated data and services in the area of atmospheric sciences, including access to instrumented platforms, services tailored for scientific and technological usage, and training opportunities. The user strategy continuously evolves within a cyclic process for optimization and improvement to ensure alignment with the overall ACTRIS strategy. The purpose of this document is to provide an update of the user strategy in the context of the operational service provision within ACTRIS ERIC, established in 2023, with a focus on physical and remote/hybrid access. Particularly addressed is the evolution of the user needs and related requirements of the service design and service provision and access system as well as the challenges that are linked to this process. To be inclusive, statistical information on access provision in the perimeter of ACTRIS is documented, particularly since 2016 when ACTRIS has entered the ESFRI (European Strategy Forum on Research Infrastructures) Roadmap. Addressed is furthermore the sustainability of access which is considered vital to ensure a successful service provision and to guarantee a positive and satisfactory experience for all ACTRIS users.
