The Square Kilometre Array Observatory (SKAO) is a large, next-generation radio telescope that is planned to be many times more sensitive than the current most sensitive telescopes in the world and transform our view of the Universe. It is a global mega-science project involving scientists and engineers from institutes and industry partners in 16 member countries. The Observatory comprises two telescope facilities; one located in South Africa, SKA-MID, to observe radio frequencies between 350MHz and 15.4GHz, and one located in Australia, SKA-LOW, to observe lower band frequencies between 50MHz and 350MHz. The SKAO's Global Headquarters (HQ), from where the SKA Design Authority directs and manages the whole SKA Programme, is adjacent to the University of Manchester's (UoM's) Jodrell Bank Observatory (JBO), home to the iconic Lovell telescope and operational HQ of the e-MERLIN interferometer, an SKA Pathfinder instrument. The SKA is one of a small number of flagship astronomical instruments that will span the entire electromagnetic spectrum from radio to gamma rays, and beyond the electromagnetic spectrum to gravitational waves, cosmic rays and neutrinos, and whose collective aim is chart the full history of the universe from its beginnings in the Big Bang to the present day. The operation of the SKA Observatory assumes the existence of SKA Regional Centres (SRCs) to deliver a range of support to the science community. The SRCs are required in order to provide the main portal for scientists to access the SKA including provision of computing resources and support to enable the science user community to analyse and extract science from data products produced by the SKA. An SRC Network (SRCNet) will be made up of SRCs distributed around the world in SKA Member countries. Each SRC will be required to conform to agreed standards in protocols, data architecture and information management policies to ensure that they appear as a single federated entity to SKA users. The SRCNet will provide a collection of both services and infrastructure that will comprise a global capability to distribute, process and curate the data from the SKA telescopes. The SRCNet will provide the basic governance and operational model and structures, and the baseline functionality of the SRC network. SKAO member states and SRC stakeholders are already engaging in the design of the SRC Network.This joint proposal aims to deliver a working prototype of an SKA Regional Centre (SRC) node that will have 20% of the capacity and 80% of the functionality required by a SRC node when SKA becomes fully operational. The UK's contribution to this work will bring international expertise in the areas of wide field radio interferometry, all sky pulsar and transient detection, the characterisation of radio flux data, e-infrastructure, advanced cloud technologies, cloud and hardware platforms, remote job provision, high throughput network and data movement, big data performant storage systems and hierarchies, identity management, scientific computing, high performance and GPU computing, the FAIRirification of digital artifacts, the automated archiving, curation, collection and co-ordination of data artifacts. All these are needed for a programme of work from 2023-2025 to ensure workflows with large datasets (>10-100TB) are tractable on the proposed UKSRC proto-node by 2024 to prepare the UK SKA Science Community for SKA science and to allow the UK to participate in SKA engineering commissioning work from 2024 onwards.

平方公里阵列天文台（SKAO）是一个大型的下一代射电望远镜，计划比世界上当前最敏感的望远镜更敏感，并改变了我们对宇宙的看法。这是一个全球大科学项目，涉及16个成员国的研究所和行业合作伙伴的科学家和工程师。天文台包括两个望远镜设施；一个位于南非的SKA-MID，可观察350MHz至15.4GHz之间的无线电频率，并位于澳大利亚，SKA-LOW，以观察50MHz和350MHz之间的较低带频率。 SKAO的全球总部（HQ）从SKA设计管理局指导和管理整个SKA计划的地方，毗邻曼彻斯特大学（UOM'S）Jodrell Bank天文台（JBO），它是标志性Lovell TeleScope和E-Merlin的HQ的标志性Lovell TeleScope和E-Merlin HQ的所在地。 SKA是少量的旗舰天文仪器之一，它将跨越从无线电到伽马射线的整个电磁谱，除了电磁频谱到引力波，宇宙射线和中微子，并且其集体目标是从宇宙开始的整个宇宙历史。 SKA天文台的运作假设SKA区域中心（SRC）的存在为科学界提供了一系列支持。为了为科学家提供访问SKA的主要门户，需要SRC，包括提供计算资源和支持，以使科学用户社区能够从SKA生产的数据产品中分析和提取科学。 SRC网络（SRCNET）将由SKA成员国在世界各地分发的SRC组成。每个SRC都必须符合协议，数据架构和信息管理策略中的商定标准，以确保它们作为SKA用户的单一联合实体出现。 SRCNET将提供服务和基础架构的集合，该服务将构成从SKA望远镜中分发，处理和策划数据的全球能力。 SRCNET将提供基本的治理和操作模型和结构，以及SRC网络的基线功能。 SKAO成员国和SRC利益相关者已经在设计SRC网络的设计。该联合提案旨在提供SKA区域中心（SRC）节点的工作原型，该原型将具有容量的20％和80％的功能，而SRC节点则在SKA开始完全运行时所需的功能。英国对这项工作的贡献将在田间无线电干涉仪，所有天空脉冲星和瞬态检测，无线电通量数据的表征，电子基础结构，高级云技术，云和硬件平台，远程作业提供，高吞吐量网络和数据移动，大数据性能管理系统和较高的计算，高度数据计算，高范围的网络运动，高级网络移动，远程范围和数据的计算，高级云技术和GP工件，数据工件的自动归档，策展，收集和协调。从2023 - 2025年开始，所有这些都是必需的，以确保在2024年拟议的UKSRC Proto-Node上使用大型数据集（> 10-100TB）进行工作流程，以便为SKA Science的英国SKA科学社区做好准备，并允许英国参与2024年的SKA工程专业工作。
