NWS Transitions to New Supercomputer on July 25, 2013

Effective with the 1200 UTC run on July 25, 2013, the NWS transitioned the operational production of the weather models to the new Weather and Climate Operational Supercomputing System (WCOSS) system. See official notification for this change.

This switch has caused a shift in model delivery, and may be affecting Unisys weather processing for the models on the Unisys Weather site. We are analyzing the new delivery times, and making adjustments to the scripts to ensure the models are processed correctly. We are aware of the issues with the RAP model graphics production.

GFSx/MRF Model Removed by NWS

As of 4/16/13, the NWS is no longer transmitting the GFSx/MRF model. Unisys Weather has updated the GFS/AVN model pages to include forecasts out to 10 days, including a new 9-panel image. Any user of the website that has hard links to the GFSx/MRF images will need to switch to the similar GFS/AVN images.

Changes to GFS Model

Effective 1200 UTC April 16, 2013, the National Weather Service will be removing the legacy GFSx grids from the NOAAPort Satellite Broadcast Network: http://www.nws.noaa.gov/om/notification/tin13-08gfs_mrf_removal.htm . This will result in Unisys Weather discontinuing the current GFSx on both WeatherMAX and the Unisys Weather website. The current 10-day GFSx forecast panels ( http://weather.unisys.com/gfsx/9panel/gfsx_pres_9panel.gif ) will be replaced with 10-day GFS “hi-res” plots ( http://weather.unisys.com/gfs/9panel/gfs_pres_9panel.gif ). A notice will be placed on the current GFSx images, for those directly linking to the plots.

The 10-day panel with the operational GFS is now online at: http://weather.unisys.com/gfs/gfs.php?inv=0&plot=pres&region=us&t=9p

Unisys NOAAPORT Gateway: Open Communications

Mission critical systems not only need to effectively ingest and process data and products, but also need ways of quickly distributing those products to users.

Each Unisys NOAAPORT Gateway is packaged with software that supports up to 32 end users through separate TCP/IP socket connections. Each system is configurable to send the data and products through one of three formats: WXP (Unisys Weather Processor), LDM (Unidata’s Local Data Manager), and GWIP (Unisys Weather Server).

Users connected to the NOAAPORT Gateway can be configured to receive any of the three formats, from any NOAAPORT or Unisys channel, separately from each other. This allows for custom configurations for each user, ensuring they receive only the products they request. In addition, Product Arrival Notifications (PAN) messages can be set up to alert users for specific sets of products, such as NWS generated watches, warnings, or advisories.

Unisys NOAAPORT Gateway: Built for Reliability

Weather data and environmental products are considered essential information for customers to help carry out their mission to protect property and save lives. However, many users rely upon a single entry point for this information. In the event of a communications failure or a lost signal, critical weather information may be missed.

Unisys designed the NOAAPORT Gateway to provide a reliable flow of weather information by outfitting the system with separate, redundant data feeds. Users can obtain the NOAAPORT Government broadcast as well as products from the Unisys 5th NOAAPORT channel via satellite downlink, with an option for landline access to the Unisys WeatherMAX data dissemination servers. In the event of a failure of the primary communication links, the Unisys NOAAPORT Gateway will automatically fail over to the backup feed, without the need for manual switching.

Government agencies such as the National Weather Service (NWS) National Centers for Environmental Prediction (NCEP) rely on Unisys to provide redundant data feeds in order to ensure critical weather data are reaching the forecasters that need the data, 24 hours per day, 365 days per year. Several large companies that specialize in weather product services also rely on the Unisys NOAAPORT Gateway solution for the very same reason.
