Subject: Changes to the NWS Production Suite1. The transition to the next Central Computer System is expected to begin in August 2006. A moratorium on changes to the NCEP Production Suite will begin in August and conclude when the new system becomes operational in January 2007. The Snow system is scheduled for shutdown on Thursday, 15 June. As of 7 June users have been given access to the temporary replacement for Frost and Snow (AQUA). There may be periods during the first few weeks when the system is unavailable due to testing and tuning of the operating system. More details on the transition schedule will be provided as they become available. 2. On Monday, 5 June the NWS Telecommunications Operations Center (TOC) announced the availability of the ftp and http access to the replacement gateway system (tgdata.nws.noaa.gov). The TOC is currently in the process of transitioning customers to the tgdata server. When that transition is complete, they will declare the system fully operational. Both GRIB1 to GRIB2 data are currently available on this new server. To conserve bandwidth, GRIB2 data is being transferred to tgdata and then converted to GRIB1. For that reason, GRIB2 data will be available one to two minutes earlier on average. At the current time some GRIB1 ensemble data is taking ten to fifteen minutes to convert. NCO will continue to work to reduce that delay. Both sets of data will remain on the TOC FTP server for a minimum of 180 days after the system is declared operational. More information will be provided on this transition as it becomes. 3.
