Observations and network assessment values are different

Two possible reasons why weather data from a point on a network is not exactly the same as the data from the network adjacent to that point on the map are:

• Observed and modeled (assessment and forecast) surface state data: When looking at the current situation on the map, the sensor point shows the latest observed data, whereas the data from the network adjacent to that point is the latest modeled data. When the observed readings show the presence of treatment material after an action, the surface state is displayed as treated and wet. The modeled data reflects the situation assuming no treatment action was undertaken. In order to make sure that all road segments are represented the same way, we do not assume a treatment was applied on a whole road based on the readings from a weather station.
• Update frequency: The observed and modeled data on the map from point locations updates every 10 minutes, and every 30 minutes from a segment of the network. If the surface state or temperature changes relatively quickly, it may take some time for the network to synchronize with the point, as it is updated less frequently. This situation will remedy itself the next time the network data is updated.
