Corridor Integrated Weather System ( CIWS) Data Publication

1. Precipitation with ET Annotation, SEP, and 30/60 minute forecast contours Corridor Integrated Weather System (CIWS) Data Publication Corridor Integrated Weather System (CIWS) products range from current weather depictions, including growth and decay trends, to convective weather forecasts, including precipitation and echo tops, out to two hours. CIWS products are made available to traffic managers and area supervisors where the products are used to support traffic management decisions during convective weather events. CIWS has been shown to narrow the gap between unavoidable delay and actual delay associated with convective weather by supporting traffic managers in making use of available capacity during storms that, in the past, would have been lost. Traffic managers make use of this available capacity by keeping jet routes open longer and opening closed routes earlier. With low topped storms as depicted by the CIWS echo tops and echo tops forecast products, traffic managers are also able to exploit over-the-top routing. CIWS products have also been made available to some AOCs to provide common situational awareness among users. The SWIM Segment 1 CIWS Data Publication Service will make CIWS data products available to all AOC external NAS users. The services will publish both image and binary encoded data to serve the varied needs of the consumers. These data services using SWIM standards will enable wider access to weather products furthering common situational awareness. In addition, standards based weather product formatting will reduce integration costs. Echo Tops (ET) with annotation Product Fact Sheet – CIWS Data Publication
