Abstract

Climate change represents an important and critical challenge for several scientists and researchers. Increasingly complex simulation models, management of petabytes of datasets (which are already too massive for current storage devices) are issues that must be faced up to in climate centres. Key elements that must be taken into account are strongly connected both with data and metadata management. Indeed, petabytes of climate data, big collections of datasets are continuously produced, delivered, accessed, processed by scientists and researchers from multiple sites at an international level. Despite the classical approaches, data-grid-enabled solutions greatly address scalability (users, data, queries, etc.), transparency (access, integration, management, presentation) and efficiency (performance) allowing the management of huge and distributed datasets. Taking into consideration the climate data growth rate, a full decentralized schema for the management of data and metadata (addressing data availability, scalability, site autonomy and efficiency) represents the most suitable solution in the proposed environment. This work presents the Euro-Mediterranean Centre on Climate Change (CMCC) initiative, discussing data and metadata issues and dealing with both architectural and infrastructural aspects concerning the adopted grid enabled solution. A complete overview of the grid services deployed at the Centre is presented as well as the client side support (CMCC data portal and monitoring dashboard).
