Virtual labs are emerging as a key component in the construction of future digital environments, particularly to abstract over the complexities of the underlying distributed networks of sensors and associated computational infrastructure. We define a virtual lab as a transdisciplinary collaboration space hosted in the cloud (public/private/hybrid) that allows stakeholders to access a range of data, analytical methods and assessment tools (e.g. visualisation tools and/or statistical tools), and to execute these analyses using the elastic capacity of a cloud. In the environmental science community, most existing virtual labs focus on the problem of integrating often complex and heterogeneous data. We seek to significantly advance the state-of-the-art by enhancing virtual labs with sophisticated methodological capability, embracing state-of-the-art data science techniques to assist in the societally-relevant interpretation of these data. This is a bold and broad vision and to make this feasible in a year we elect to work with a particular family of data science techniques, that is changepoint detection methods, designed to identify fundamental changes and anomalous behaviour in data, typically within time-series, but also applicable across space and time and to complex, multivariate problems.This feasibility study will therefore bring together a cross-disciplinary team working on virtual labs, changepoint methods and evidence for impacts of global environmental change on ecosystem structure and function. Our approach will foster a deep, cross-disciplinary dialogue through workshops, enhanced by rapid prototyping of virtual labs to stimulate thinking about what is possible/desirable w.r.t. ecosystem early warning methods.The project will build on the rich, complex, multi-faceted data available from the Environmental Change Network (ECN), that offers detailed multivariate 25-year long data sets for a range of ecosystems in the UK. We seek to understand the role of data science, including but not limited to changepoint detection, in the construction of environmental early warning alert systems capable of operating at a variety of scales, from catchments to global planetary level systems.

虚拟实验室正在成为构建未来数字环境的关键组成部分，特别是在抽象传感器和相关计算基础设施的底层分布式网络的复杂性方面。我们将虚拟实验室定义为托管在云(公共/私有/混合)中的跨学科协作空间，允许利益相关者访问一系列数据、分析方法和评估工具(例如可视化工具和/或统计工具)，并使用云的弹性容量执行这些分析。在环境科学界，现有的大多数虚拟实验室都专注于集成往往复杂和异质的数据。我们寻求通过增强具有复杂方法能力的虚拟实验室，采用最先进的数据科学技术来帮助对这些数据进行与社会相关的解释，从而显著推进最先进的技术。这是一个大胆而广泛的愿景，为了在这一年实现这一目标，我们选择使用一系列特定的数据科学技术，即变点检测方法，旨在识别数据中的基本变化和异常行为，通常在时间序列内，但也适用于跨空间和时间以及复杂的多变量问题。因此，这项可行性研究将汇集一个跨学科团队，致力于虚拟实验室、变点方法和证据，以研究全球环境变化对生态系统结构和功能的影响。我们的方法将通过研讨会促进深入的、跨学科的对话，并通过虚拟实验室的快速原型来促进，以激发对什么是可能/可取的w.r.t.的思考。生态系统预警方法。该项目将建立在环境变化网络(ECN)提供的丰富、复杂、多方面的数据基础上，该网络为英国的一系列生态系统提供详细的多变量25年长数据集。我们试图了解数据科学，包括但不限于变点探测，在构建能够在从集水区到全球行星系统的各种尺度上运行的环境预警系统方面的作用。
