Integrated Terminal Weather System (ITWS) Data Publication

1. Integrated Terminal Weather System (ITWS) Data Publication Integrated Terminal Weather System (ITWS) improves NAS efficiency (and enhances NAS capacity) by displaying the impact of convective weather, storm cells, precipitation, airport winds, microbursts, gust fronts, windshear, lightning, and tornadic activity at selected NAS pacing airports to AOC dispatchers and traffic managers at the ATCSCC, ARTCCs, ATCTs, and large TRACONs. With this real-time picture of convective weather at pacing airports, traffic managers can collaborate with dispatchers to route/re-route traffic as necessary. Traffic Managers track storm activity at major NAS airports, manage the airport acceptance rates (AAR), and facilitate the flow of traffic in order to mitigate the impact of weather on NAS operations. This promotes common situational awareness, which is absolutely crucial to the collaborative decision making process that is necessary to reduce weather-related delays. The SWIM provided ITWS Data Publication Service will improve on this by providing ITWS products digitally to the AOCs and other subscribers that supports overlay of ITWS products onto user workstations for greater common situational awareness. Further, engineering these data services using SWIM standards will reduce integration costs while enabling wider access to weather products. Product Fact Sheet – ITWS Data Publication
