The SwissMetNet monitoring network
SwissMetNet is the automated reference network for ground-level measurements operated by MeteoSwiss. The number of automatic monitoring stations within SwissMetNet has been increased significantly in recent years based on continuous monitoring of the requirements (for the protection of people and goods during extreme weather events, for the aviation sector, for cantonal and federal authorities, for nuclear safety and short-term forecasts, for civil society and the military and for weather forecasting and climatology). While the basic infrastructure and most of the meteorological instruments are in excellent condition, the electronics for the data collection and communication are nearing the end of their service life.
The SwissMetNet Acquisition and Data Communication (SMN ACDC) project
At the end of 2018, the management at MeteoSwiss decided to introduce the SMN ACDC project with the aim of renewing the data collection and communication infrastructure for the SwissMetNet monitoring network. The project prioritises the quality and resilience of the network while at the same time striving to reduce investment and operating costs as far as possible. A comprehensive feasibility study indicated that all of the various needs could be fully met through the use of the Internet of Things (IoT) and cloud technologies, and that this approach would also have financial advantages. The management has endorsed this new focus on data transmission technologies, and has tasked the project team with implementing the new solution. This strategy is in line with the Swiss federal government’s innovation and automation strategy and, in particular, its cloud strategy. It ensures the long-term resilience of our operations, which is equally one of the strategic goals of MeteoSwiss.
The project involves two phases to prepare the new system for deployment. The first preparatory phase was completed at the end of 2022 for ten stations. This phase provided the opportunity for the new solution to be evaluated and, where necessary, for minor modifications to be carried out. A second preparatory phase will take place in 2023. After a second validation phase, the project will then enter its implementation phase, to run from 2024 to 2026, during which the solution will be installed in all SwissMetNet stations.
