Subject: Add Geostationary Operational Environmental

         Satellite–16 (GOES-16) Imagery to the Satellite

         Broadcast Network (SBN or NOAAPORT), effective

         March 2, 2017

 

Effective on or after Thursday, March 2, 2017, at approximately

18UTC, GOES-16 Advanced Baseline Imager (ABI) Sectorized Cloud

and Moisture Imagery (SCMI) will be added to the SBN (also known

as NOAAPORT).

 

The SBN feed of GOES-16 ABI imagery will be in a pre-operational

validation and testing phase through approximately November

2017. NOAA's GOES-16 satellite has not been declared operational

and its data are preliminary and undergoing testing. Users

receiving these data through any dissemination means assume all

risk related to their use of GOES-16 data and NOAA disclaims any

and all warranties, whether express or implied, including

(without limitation) any implied warranties of merchantability

or fitness for a particular purpose. 

 

This preliminary imagery is being added to enable the testing of

networks and systems with actual GOES-16 imagery and so that

users will be able to evaluate the imagery during this

validation/test period. It is not recommended that this

preliminary imagery be used in operational forecast processes,

especially during the initial months of this validation/test

period.  Any downstream postings of these data should clearly

convey their preliminary, non-operational and in-testing nature. 

Furthermore, this data stream may be subject to temporary

unannounced data outages during this validation and testing

period. One or more follow-on notices will provide information

on the progress and conclusion of the validation period.

 

Refer to prior Technical Implementation Notice 15-24, which

introduced simulated GOES-R data to the SBN.

Eventually, the SBN will carry a range of GOES-16 products. 

This notice concerns only the addition of GOES-16 ABI imagery. 

A future notice will be issued for other GOES-16 products that

will be added to the SBN at a later date.

 

GOES-16 is stationed over its designated 89.5 degrees west

longitude station. From this location, it is undergoing checkout

and validation and is not yet designated GOES East or West.

Nevertheless, the SBN's GOES-R East channel (PID 108) will be

used to disseminate the GOES-16 imagery, at least until the time

when the spacecraft is repositioned to its final operational

station. For the foreseeable future, the operational GOES-East

(GOES-13) and GOES-West (GOES-15) data will remain unchanged on

SBN PIDs 102 (for CONUS imagery) and 104 (for OCONUS imagery). 

 

The WMO headers for the GOES-16 imagery are as follows, with

references to the 11 character template:

 

Template: T1 T2 A1 A2 ii CCCC

 

  T1 = T

  T2 = I

  A1 = R for large-scale (non-mesoscale) sectors

     = S for mesoscale sectors

  A2   Where A1=R, for large-scale (non-mesoscale) sectors, A2

       corresponds to geographical sectors as follows:

     = A for the Alaska Regional sector

     = E for the East CONUS sector

     = H for the Hawaii Regional sector

     = P for the Puerto Rico Regional sector

     = S for the East Full Disk

     = T for the West Full Disk

     = W for the West CONUS sector

       Where A1=S, for mesoscale sectors, A2 values corresponds

       to geographical latitude/longitude areas as follows:

     = A for 45 deg. N <= Lat. < 60 deg. N and

             120 deg. W < Long. <= 135 deg W

     = B for 45 deg. N <= Lat. < 60 deg. N and

             105 deg. W < Long. <= 120 deg. W

     = C for 45 deg. N <= Lat. < 60 deg. N and

             90 deg. W < Long. <= 105 deg. W

     = D for 45 deg. N <= Lat. < 60 deg. N and

             75 deg. W < Long. <=  90 deg. W

     = E for 45 deg. N <= Lat. < 60 deg. N and

             60 deg. W < Long. <=  75 deg. W

     = F for 30 deg. N <= Lat. < 45 deg. N and

             120 deg. W < Long. <= 135 deg. W

     = G for 30 deg. N <= Lat. < 45 deg. N and

             105 deg. W < Long. <= 120 deg. W

     = H for 30 deg. N <= Lat. < 45 deg. N and

             90 deg. W < Long. <= 105 deg. W

     = I for 30 deg. N <= Lat. < 45 deg. N and

             75 deg. W < Long. <=  90 deg. W

     = J for 30 deg. N <= Lat. < 45 deg. N and

             60 deg. W < Long. <=  75 deg. W

     = K for 15 deg. N <= Lat. < 30 deg. N and

             120 deg. W < Long. <= 135 deg. W

     = L for 15 deg. N <= Lat. < 30 deg. N and

             105 deg. W < Long. <= 120 deg. W

     = M for 15 deg. N <= Lat. < 30 deg. N and

             90 deg. W < Long. <= 105 deg. W

     = N for 15 deg. N <= Lat. < 30 deg. N and

             75 deg. W < Long. <=  90 deg. W

     = O for 15 deg. N <= Lat. < 30 deg. N and

             60 deg. W < Long. <=  75 deg. W

     = P for 0 deg. N <= Lat. < 15 deg. N and

             90 deg. W < Long. <= 135 deg. W

     = Q for 0 deg. N <= Lat. < 15 deg. N and

             60 deg. W < Long. <=  90 deg. W

     = R for 45 deg. N <= Lat. < 90 deg. N and

             135 deg. W < Long. <= 180 deg. W

     = S for 0 deg. N <= Lat. < 45 deg. N and

             135 deg. W < Long. <= 180 deg. W

     = T for 60 deg. N <= Lat. < 90 deg. N and

             90 deg. E < Long. <= 135 deg. W

     = U for 0 deg. N <= Lat. < 60 deg. N and

             90 deg. E < Long. <=  60 deg. W

     = V for 0 deg. N <= Lat. < 90 deg. N and

             180 deg. W < Long. <=  90 deg. E

     = W and X are reserved for future use

     = Y for 90 deg. S <= Lat. <  0 deg. S and

             105 deg. W < Long. <=  90 deg. E

     = Z for 90 deg. S <= Lat. <  0 deg. S and

             90 deg. E < Long. <= 105 deg. W

 

Where mesoscale boxes T, U and Z extend across the prime

meridian (0 deg. longitude) and boxes V and Y extend across the

International Dateline (180 deg. longitude).  Sector boundaries

of 0 deg. N or 0 deg. S refer to the equator.  The "<=" symbols

refer to "less than or equal to."  Note that some of the regions

above are out of range from GOES-16 at its current location, but

these regions could be within range after the satellite’s

station changes.

 

 

  ii = ABI channel number (01 - 16); between the ii and CCCC is

       a space

 

  CCCC = KNES (signifies that NESDIS is the creating data

         center)

 

During this test and evaluation period, some sectors will be

unavailable, and the set of available sectors will change.

 

Until recently, these headers had been used to disseminate

simulated imagery on the GOES-R East channel for GOES-R testing.

Tests of simulated GOES-R Series imagery will occur, at times,

on the GOES–R West channel of the SBN.

 

The file format for these products is netCDF4.

 

Additional information about this new data stream (including

headers, file-format descriptions, sector definitions, sample

files and further information) has been posted at the following

web site and will be periodically updated:

 

http://www.nws.noaa.gov/noaaport/html/GOES_R.shtml

 

Critical weather or other factors could delay the activation of

these products on the SBN.
