ENES-RI Services: Services of the European Network for Earth System Modelling Research Infrastructure

Effective climate policy and pathways out of the climate crisis require open, reliable, and actionable projections of Earth’s climate system. This project will deliver an improved and comprehensive portfolio of services from the European Network for Earth System Modelling Research Infrastructure (ENES-RI), aiming to streamline, facilitate, and accelerate the production of these projections and their use in science and policy. The services will achieve this by supporting users in overcoming key challenges: the increasing complexity of Earth system models (ESMs), their evaluation needs, the unprecedented data volumes they produce, and their adaptation to evolving high-performance computing (HPC) environments.The ENES-RI Services (ENES-RISe) project will address these challenges by delivering services based around four thematic pillars: ESMs and related key infrastructure tools, HPC adaptation and performance optimization, data distribution and standards, and tools for the evaluation of ESM output. In this last pillar, ENES-RISe will streamline the use of data from key European observational research infrastructures in ESM evaluation. Services in these pillars will target key user communities: climate modellers and researchers, the climate change impacts community, and climate services. Service discovery and adoption will be facilitated via a new unified catalogue of services, and targeted dissemination measures to expand the user base. ENES-RISe will be a major component of the European contribution to the international coordinated experiments of the World Climate Research Programme, and the related data distribution network, the Earth System Grid Federation.ENES-RISe will be delivered by a consortium with a long history of collaboration in delivering software, computing, and data services to climate modellers, researchers, and the broader user base of ESM simulations, and who are in the process of formalising that collaboration to ensure long-term sustainability.
