Vaisala Oyj is a Finnish industrial-measurement and weather-intelligence group headquartered in Vantaa (greater Helsinki), listed on Nasdaq Helsinki with global revenue near €580 million. Vaisala’s AviMet AWOS (Automated Weather Observing System) and ICAO-compliant AUTO METAR sensors are deployed at Portuguese civil-aviation sites, supporting Portugal’s METAR observation network including Funchal (Madeira, LPMA) among others.
Vaisala is one of Finland’s flagship industrial-technology exporters, founded in 1936 and listed on Nasdaq Helsinki. The group serves three core markets — weather and environment, industrial measurements, and aviation — with a long history of building reference-grade meteorological instrumentation deployed by national weather services, airports and energy operators worldwide. Group revenue has grown to roughly €580 million in recent reporting periods, and Vaisala is consistently among the technology vendors that publish ICAO-compliant METAR and TAF reference solutions used across Europe.
In Portugal, Vaisala’s AviMet Automated Weather Observing System and AUTO METAR-capable sensors form part of the equipment supporting Portuguese civil-aviation weather observation, including the METAR feeds visible at Funchal/Madeira (ICAO: LPMA). The deployment fits the broader pattern: Vaisala’s reference customers in airport meteorology include both Portugal and Finland, where similar AWOS configurations underpin AUTO METAR generation for civil and military aviation operators.
Vaisala is a quietly structural part of the Portuguese aviation safety system. Its instruments are not consumer-visible, but they sit at the centre of every METAR report Portuguese airports publish — a high-trust, regulated technology footprint that anchors Finnish industrial measurement inside Portuguese critical infrastructure.
Vaisala continues to update its FD70 and AviMet weather codes for SYNOP/METAR/NWS use, with documentation references for Portuguese airport AUTO METAR observation. No new 2026 Portuguese contract has been publicly disclosed, but Vaisala-equipped METAR feeds remain visible across Portuguese aviation weather portals.
