Vaisala is a leading supplier of automated weather observing systems for airports. Vaisala AviMet® aviation weather management solutions integrate weather data into all your processes enhancing safety, business predictability and performance. Vaisala AviMet® comprises of the technology platform, services, and a growing set of end-user applications ranging from ATC to de-icing applications.

ICAO compliant AWOS and RVR systems

The Vaisala AviMet® Automated Weather Observing System (AWOS) is an integrated airport weather observing system for regional, national and international airports. It calculates aviation meteorological data such as pressure values (QFE, QNH), Runway Visual Range, and generates METAR, SPECI and SYNOP reports. The system can be configured to suit the requirements of the aviation site in question: ICAO categories up to CAT III are covered.

The Vaisala AviMet® Runway Visual Range System (RVR) provides fully automated runway visual range assessment and reporting for air traffic control at airports. It comprises of visibility sensors, background luminance meters and a computer that calculates the RVR values. Visibility sensors are offered in two forms: transmissometers or forward scatter meters. The RVR computer collects the visibility data from the visibility sensors, the background luminance data from the background luminance meters, and runway light setting data from a dedicated interface unit. It calculates the RVR values on the basis of this data, and distributes the RVR messages and alarms to output devices such as computer terminals, chart recorders and digital displays.

The Vaisala AviMet® AWOS and RVR Systems conform to all relevant ICAO and WMO recommendations and regulations.

Vaisala AviMet Low-Level Windshear Alert System (LLWAS)

The Vaisala AviMet® Low-Level Windshear Alert System detects low-level wind shear in runway corridors. It is ground-based, giving visual and audio alerts in numerical and/or graphical formats. At airports that are known to experience low-level horizontal windshear, the AviMet LLWAS can be fundamental to improving safety and operating efficiency.

Runway and ramp systems

The Vaisala IceCast Ice Warning and Prediction System assists runway and ramp maintenance personnel to make good maintenance decisions in bad weather. Timely and accurate winter maintenace decisions, e.g. correctly scheduled de-icing, can significantly decrease the runway winter maintenance costs and ensure that the runway can be kept operation even during harsh winter weather. IceCast integrates data from Vaisala Weather Stations, forecasts from the local forecast provider, forecasts generated by Vaisala forecast generation software and Thermal Mapping data into a single system.

The Vaisala Thunderstorm Warning System TWX300 is aimed at operations that are susceptible to injury and damage caused by lightning. The TWX300 tracks lightning and monitors the potential for lightning developing overhead, and it automatically sends lightning warnings to remote alarm displays. In the main application, lightning warning areas and electric field mills are monitored in real-time. Remote alarm displays, email notifications, and relays are triggered once a lightning warning is issued by the TWX300 workstation. TWX300 is designed for working environments that are most vulnerable to the hazards of lightning and need up-to-the second 24/7 lightning tracking, and automated lightning warnings including airports, explosives testing, mining and blasting operations, munitions depots, refineries and sporting facilities.

Vaisala Global Lightning Dataset GLD360

The Vaisala Global Lightning Dataset GLD360 provides users with access to world-wide real-time lightning information for accurate and early detection and tracking of severe weather. The data is generated by world-wide network, owned and operated by Vaisala It is the first truly global and accurate lightning coverage. The Vaisala Global Lightning Dataset GLD360 is offered as a service and thus requires no investment in hardward. There is no need to own equipment and no maintenance concerns. It can be delivered within a week which enables the user to quickly provide better service to the end-users. 
The Vaisala Global Lightning Dataset GLD 360 fills in the gaps in the radar coverage. It enhances forecasting and early warning capability for thunderstorms and cyclons. It gives complete uniform global coverage. Cloud-to-ground lightning is detected instantly and data is delivered in less than two minutes. It detects lightning the moment it happens, anywhere over land and sea. The accuracy of GLS360 exceeds all other long-range systems, including satellite data. It detects about 7 out or 10 lightning flashes worldwide, with a location accuracy of 5-10 km.
