Vaisala IceCast Fog Warning System

The hazards of fog can be managed using the Present Weather Detector (PWD) range of instruments, supplemented by Vaisala Weather Cameras. Both instruments can be installed as an integral part of ROSA weather stations or as stand-alone solutions. Data can be displayed via IceView or IceWeb. 

These solutions may be integrated with VMS technology to provide road and bridge users with warning/advisory information. Road weather solutions typically use the PWD12 measuring visibility with a range of 10-2000m. 

There are several Vaisala Traffic Weather Camera options available, depending on the location of the weather station.
