NOAAPORT NOTICE NO. 21     AUGUST 31... 1999

ATTENTION   NOAAPORT USERS

THE GOES INGEST NOAAPORT INTERFACE /GINI/ WAS IMPLEMENTED
MORE THAN FIVE YEARS AGO AS THE REALTIME GOES SATELLITE
INGEST... REMAP AND DISTRIBUTION SYSTEM FOR AWIPS.  THE
TECHNOLOGY WAS AGING... HARDWARE COMPONENTS BECAME
OBSOLETE... AND THE SOFTWARE AND FIRMWARE WERE NOT YEAR
2000 COMPLIANT.  NESDIS HAS ADDRESSED THESE PROBLEMS AND
OTHER GINI CONCERNS BY RECREATING THE GINI FUNCTIONS ON A
MODERN OPEN SYSTEMS PLATFORM.

THE NEW GINI... KNOWN AS GINI2... WILL PROVIDE THE REAL TIME
GOES SATELLITE SERVICES TO THE AWIPS PROGRAM BEGINNING IN
SEPTEMBER 1999.  GINI2 INCLUDES SEVERAL ENHANCEMENTS... SOME
OF WHICH ARE THE RESULT OF COOPERATIVE PROBLEM SOLVING
BETWEEN THE NWS AND NESDIS.   IN ADDITION TO BEING ABLE TO
CONTINUE PROCESSING THROUGH THE YEAR 2000 ROLL OVER...
GINI2 SECTOR CORNER POINTS HAVE BEEN FINE TUNED AND THE
REMAPPING PROCESS ON GINI2 IS NOW BASED ON AN ELLIPTICAL
EARTH MODEL.  ALSO... THE SATELLITE IMAGES WILL APPEAR LESS
BLOCKY AND PROVIDE A GREATER RANGE OF CALIBRATION VALUES.
DETAILS OF THE CHANGES MAY BE FOUND IN THE RECENTLY
REVISED AWIPS NESDIS ICD DATED AUGUST 1... 1999.  THIS DOCUMENT
WILL SOON BE AVAILABLE FOR DOWNLOAD ON THE NWS NOAAPORT
HOMEPAGE AT

WWW.NWS.NOAA.GOV/NOAAPORT/HTML/NOAAPORT.SHTML.

THE CHANGE IN EARTH MODEL AND SECTOR CORNER POINTS MEAN
THAT FIELD OFFICE AWIPS WORKSTATIONS WILL NEED A SOFTWARE
CHANGE /PATCH/ TO DISPLAY THE GINI2 DATA CORRECTLY.  THE
SOFTWARE CHANGE WILL BE DISTRIBUTED TO NWS SITES DURING
EARLY SEPTEMBER IN TIME FOR IMPLEMENTATION ON OR ABOUT
SEPTEMBER 20... WHEN THE GINI2 WILL BEGIN PRODUCTION.  A FINAL
NOTICE OF THE GINI2 OPERATIONAL SWITCHOVER WILL BE
TRANSMITTED SHORTLY BEFORE THE SCHEDULED DATE AND TIME.
QUESTIONS SHOULD BE DIRECTED TO RON SMITH AT

RONALD.SMITH/AT SYMBOL/NOAA.GOV OR /301/ 713-0070 X 162.
