This international, English-language journal publishes original, interdisciplinary articles on all aspects of informatics dealing with the Earth system. Informatics is the science of the application of formal and computational methods to the systematic analysis, management, interchange, and representation of information and knowledge. Earth Science Informatics, as a scientific discipline, focuses on two major aspects: (i) the formal representation of the spatial and temporal relationships between entities in the Earth system and (ii) the design, development, and application of computational tools to acquire, store, analyze, visualize, manage, represent, utilize and communicate information about the spatio-temporal dynamics of the Earth system.
