SIOS (Svalbard Integrated Arctic Earth Observing System) is a collaborative effort to develop and maintain a regional observational system for long-term measurements in and around Svalbard, addressing Earth System Science questions related to Global Change. SIOS integrates the existing distributed observational infrastructure and generates added value for all partners beyond what their individual capacities can provide.
SIOS brings observations together into a coherent and integrated observational programme that will be sustained over a long period. Within SIOS, researchers can cooperate to access instruments, acquire data and address questions that would not be practical or cost effective for a single institution or nation alone.
SIOS is one of the new blue data infrastructures federated in Blue-Cloud 2026, making its data available via the Data Discovery & Access Service.
