Steilene Weather Station
Technicians from Nortek deploying the AWAC just outside the island.
For the population of Oslo we are running a public available weather station. The value of this station has long been recognized by mariners and recreational boaters alike.
The station is setup on Fyrsteilene, a small island in the Oslo Fjord, and has been operational since 2008. The station is powered by solar cells and as a result it requires almost no maintenance.
The AOS unit controls the sensors and transfers the collected data via satellite.
