SUBJECT: Changes to the NWS Production Suite1. GRIB1 to GRIB2 migration - NCEP is providing new data sets to the NWS (tgftp.nws.noaa.gov) and NCEP (ftp.ncep.noaa.gov) servers in GRIB2 format only. GRIB1 legacy products will continue to be populated on the servers through January of 2008. An official Technical Implementation Notice (TIN) will be disseminated by NWSHQ in July 2007 informing users that all GRIB1 formatted products will be discontinued on the servers in January 2008. It is imperative that users of GRIB1 data begin migrating over to GRIB2 format. NCEP provides free software for users to convert GRIB2 formatted data back into GRIB1 format. Please use the link below to obtain the software utility to convert formats: http://www.nco.ncep.noaa.gov/pmb/codes/GRIB2/ Information regarding product equivalents for GRIB1 and GRIB2 on the NWS FTP TOC servers (tgdata.nws.noaa.gov and tgftp.nws.noaa.gov) and NCEP ftp server (ftp.ncep.noaa.gov) can be found via the link below: http://www.nco.ncep.noaa.gov/pmb/docs/GRIB1_to_GRIB2.shtml Please direct all questions concerning the software codes to the following NCO PMB Dataflow Helpdesk: NCEP.PMB.Dataflow@xxxxxxxx 2. IBM Central Computer System (CCS) users wishing to apply for access to restricted data will find an improved form on the web at http://www.nco.ncep.noaa.gov/sib/restricted_data/restricted_data_sib/register/. The web site will be viewable only from the domains which access the IBM CCS. The form has been simplified and now includes a confirmation email back to the user upon form submission. IBM CCS users with feedback or questions specifically about the look and feel of this web site or the process of applying for restricted data access can email ncep.nco.ccsdata@xxxxxxxx. 3. Upcoming major changes to NCEP's production suite and details on any product or timing changes associated with upcoming implementations can be viewed at the following website: http://www.nco.ncep.noaa.gov/pmb/changes/ Test data for each of these proposed changes should be available six weeks prior to implementation. Anyone wishing to receive formal notice of the final pre-implementation testing and the opportunity to provide feedback on the proposed changes can subscribe to the Model Evaluation mailing list via: https://lstsrv.ncep.noaa.gov/mailman/listinfo/ncep.list.modelevalinfo <snip>
