This interdisciplinary project will for the first time provide for in-situ observations and ubiquitous data and services covering the arctic tundra that scales with the size of the observed area, the resolution of the observations, and the volume and freshness of data. This is a direct response to the Climate-ecological Observatory for Arctic Tundra (COAT) science plan stating that the circumpolar arctic tundra is the earth's terrestrial biome most challenged by climate change, but that there presently are too few observations of the arctic tundra. Therefore, there is a high demand for establishing scientifically robust observation systems to enable timely detection, documentation and understanding of climate impacts. The arctic tundra is a demanding region with severe weather, low temperatures, limited network services and energy, and often being physically inaccessible. This project advances the state of the art for cyber-physical systems being exposed to such extreme conditions. The Distributed Arctic Observatory is a novel next-generation scalable, energy sensitive, configurable, and robust observation system enabling many in-situ observations at high resolutions and at many locations throughout the arctic tundra, and with services making the data available and explorable by researchers and the public. There are many challenges facing such a system. The in-situ observation units must be made autonomous so they continue operation despite network limitations, faults, failures, and malware. Observation units have to use their limited resources in an energy sensitive way. Especially the analytics processing to find interesting objects in the observed data requires increased energy efficiency. To be useful in practise the system must be adaptable to new needs, and provide for access to data and for practical analytics and visualizations.
