This document has been prepared within the ATMO-ACCESS project and, in particular, in the framework of Work package 1 (WP1): “Developing the concept and guidelines for access to distributed atmospheric Research Infrastructures”. The main objective of WP1 is to define a synergistic framework with guidelines and cost scheme for access to atmospheric Research Infrastructures (RI) to enhance user-friendly and easy access to services provided by atmospheric research facilities in ATMO-ACCESS.Developing a unified legal framework is essential for establishing fair and effective access conditions for the whole atmospheric research community. This Deliverable aims to give recommendations on “Consolidation of access policies and legal framework for atmospheric research infrastructures”, named Task 1.2.A review of access policies from different RIs has been used as the foundation to elaborate a common policy and legal framework for accesses. That review was carried out in ATMO-ACCESS Milestone 2: Analysis of Access policies and legal framework regulating the Access provision, where the policy on access and data policies from a total of 19 RIs was examined, It was observed that some RIs present an advanced legal maturity and have developed extensive regulation in their internal policies, while regulation is scarce in others, As one of the RIs with the most developed access policy, ACTRIS has provided substantial input to this document. Additionally, policies from other RIs (IAGOS, ICOS, NFFA-Europe, INTERACT, ENVRI, etc) have also been incorporated in thisdocument.
