Vaisala ROSA (Road & Runway Surface Analyser) Weather Station
The Vaisala ROSA Weather Station provides real-time
weather and pavement data to inform decision-makers of ice, snow and low
visibility. Road / Runway Weather Stations are often also known as
'RWIS' or Environmental Sensor Sites
('ESS').
The ROSA station is compact and modular, making it easy to
expand the number of sensors attached. The standard installation reports on
surface and ground temperature, water layer thickness, air temperature,
humidity, dew point, precipitation, wind speed and direction and warns of black
ice.
The DRS511 Road/Runway Sensor plays the leading role in the
ROSA station and the system provides anti-icing concentration,
freezing point temperature and surface state.
The ROSA station can be powered from mains supply, solar
power or battery depending upon its location. Data is transferred at
configurable, regular intervals via dial-up over a PSTN or leased line, GSM,
GPRS or radio modem. Stations fitted with a DMC586 processing
unit will also transfer data directly, over the Internet.
The DMC586 enhances the capability of the ROSA weather station, enabling increased frequency of data, relay of weather camera images and use of international communication protocols.
At the heart of the ROSA weather station, these cards provide the interface between the road and atmospheric sensors and the data logger.
The ROSA weather station supports a range of communication protocols.
