Svalbard integrated Arctic Earth Observing System is an independent international research infrastructure building a regional observing system for long-term measurements in and around the High-Arctic archipelago Svalbard addressing Earth System Science questions. SIOS integrates the existing distributed observational infrastructure and generates added value for all partners beyond what their individual research can provide.

The Arctic region is experiencing the strongest climate change worldwide with changes three times as fast as in the rest of the world. The High-Arctic Archipelago Svalbard is consequently an important arena for investigations of environmental and climate change. To address these and other Earth System Science questions, the Svalbard Integrated Arctic Earth Observing System (SIOS) was established as a multi-disciplinary research infrastructure covering all important elements of the coupled Earth System in the Arctic.

The observing system and research facilities offered by SIOS build on the extensive observation capacity and diverse world-class research infrastructure provided by many institutions already established in Svalbard. This includes a substantial capability for utilising remote sensing resources to complement ground-based observations.  SIOS focuses on processes and their interactions between the different spheres, i.e., biosphere, geosphere, atmosphere, cryosphere, and hydrosphere. The core observational programme of SIOS provides the research community with systematic observations that are sustained over time. To use the observing system more efficiently, SIOS offers a range of services, including a distributed data management system, remote sensing services, logistical support and advice, webinars, and training courses.

SIOS is an international research infrastructure, hosted by Norway. SIOS entered its operational phase in 2018 and has currently 26 member institutions from 9 countries. Its central node is the SIOS Knowledge Centre located in Longyearbyen, Norway. It coordinates joint activities and coordinates the services provided by the SIOS community.
