Environmental Sensor Stations Current Surface & Atmospheric Conditions A fundamental component to a Weather Information System is collecting actual data. This is obtained from remote environmental sensor station(s) (ESS) placed at strategic points on a road network. These stations can provide invaluable information on atmospheric conditions: 
Air temperature and dew point temperature.Wind speed and direction.Pressure.Precipitation rate and type.Snow accumulation / depth.And on the road surface itself, embedded pucks can record: Road temperature (surface and sub-grade).Surface condition.Presence/concentration of ADI agent.Freeze point.Additional equipment can be added to increase the functionality of each ESS such as monitoring air quality, traffic density or provide visual links through cameras. Pelmorex can offer our expertise in: Consultative advice on ESS specifications.Consultative advice on effective siting of stations.Installation of reliable and hi-tech ESS, or network of stations including design of networks, real-time telecommunications services and communication protocols (NTCIP-ESS).Ongoing maintenance of ESS (network) by our RWIS support professionals.All services Pelmorex offer are supported by our customized training programs, and all Environmental Sensor Stations we design are fully compliant with Environment Canada and Transport Canada's Guidelines. Forecast Weather and Pavement Conditions At Pelmorex, we have a vast resource of meteorological expertise as Canada's leading independent weather company. Using ESS data from your network, we can provide reliable, accurate forecasts of atmospheric and pavement conditions in your region. Data is gathered from all available ESS's, satellite imagery, Canada's radar network, other available observations and various atmospheric numerical models (including Meteorological Services Canada's Global Environmental Multiscale (GEM) numerical model. This data is then interpreted by our dedicated, professional team of meteorologists, to produce a tailored weather forecast for each location or stretch of road. Our detailed atmospheric forecast is then input to our Road Surface Temperature (RST) model to determine safety critical variations in road surface conditions. Road Surface Temperature Model This model resolves complex heat-balance equations and accounts for local conditions such as:
