NOAAPORT Broadcast Changes
LeRoy Klet, Northrop Grumman Information Technology, McLean, VA
Due to increasing data needs at the Advanced Weather Interactive Processing System (AWIPS) field sites, the National Weather Service (NWS) is implementing changes to improve the capabilities and capacity of the NOAAPORT broadcast. The initial phase involves the compression and redistribution of Geostationary Operational Environmental Satellite (GOES) imagery. All of the existing Continental United States (CONUS) GOES imagery will be combined into a single channel (formerly GOES-EAST) with the existing Outside Continental United States (OCONUS) GOES imagery moved to the fourth data collection platform (DCP)/nonGOES imagery channel. The former GOES-WEST channel will then be available to support a new broadcast format and additional data products such as model data from National Centers for Environmental Prediction. This former GOES-WEST channel will initially be used for proof of concept testing of a digital video broadcasting (DVB) channel in late 2003. Full deployment of this single T1 data rate DVB channel for all AWIPS field sites is expected in early 2004. At a later date the entire NOAAPORT broadcast will be converted to exclusively DVB with additional satellite capacity added to reach a full transponder rate in 2005.
