Surface Transportation Weather Service (Terminator*)
This terminator represents the providers of value-added sector specific meteorological services. These providers utilize National Weather Service data and predictions (including the qualified environmental data from the Clarus system), road condition information and local environmental data provided by the traffic management or maintenance organizations, and their own models to provide surface transportation related weather observations and forecasts including pavement temperature and conditions.Inputs/Outputs: Architecture Flows* and Data Flows*
Archived Data Management
Surface Transportation Weather Service
- archive requests (Architecture Flow*) - A request to a data source for information on available data (i.e. "catalog") or a request that defines the data to be archived. The request can be a general subscription intended to initiate a continuous or regular data stream or a specific request intended to initiate a one-time response from the recipient.
Data Flows*: - archive status (Architecture Flow*) - Notification that data provided to an archive contains erroneous, missing, or suspicious data or verification that the data provided appears valid. If an error has been detected, the offending data and the nature of the potential problem are identified.

- transportation weather information request (Architecture Flow*) - A request for transportation weather information that may specify the area of interest (a geographic region, particular routes within a region, specific road segments), the type of information that is required, the desired spatial resolution of the information, and time horizon.

Surface Transportation Weather Service
- road network environmental probe data (Architecture Flow*) - Aggregated vehicle probe information that can be used to estimate current environmental conditions. Collected information would include measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, ALB status, and other collected vehicle system status and sensor information.

Surface Transportation Weather Service
- environmental conditions data (Architecture Flow*) - Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by fixed and/or mobile environmental sensors and aggregated by the data collector. Attributes relating to the data collection (and aggregation) are also included.
Data Flows*: - road data (Architecture Flow*) - Basic road facility and treatment information that supports road conditions forecasts.
Data Flows*: - road weather information (Architecture Flow*) - Road conditions and weather information that are made available by road maintenance operations to other transportation system operators.

Surface Transportation Weather Service
- environmental probe data (Architecture Flow*) - Data from vehicle safety and convenience systems that can be used to estimate environmental conditions, including measured air temperature, exterior light status, wiper status, sun sensor status, rain sensor status, traction control status, anti-lock brake status, and other collected vehicle system status and sensor information. The collected data is reported along with the location, heading, and time that the data was collected. Both current data and snapshots of recent events (e.g., traction control or anti-lock brake system activations) may be reported.
Data Flows*: - environmental sensor data (Architecture Flow*) - Current road conditions (e.g., surface temperature, subsurface temperature, moisture, icing, treatment status) and surface weather conditions (e.g., air temperature, wind speed, precipitation, visibility) as measured and reported by fixed and/or mobile environmental sensors. Operational status of the sensors is also included.
