Subject: Changes to Satellite Broadcast Network (SBN or

         NOAAPORT) Products Associated with GOES East

         Transition, Effective December 14, 2017 through

         January 3, 2018

 

Between Thursday December 14, 2017, and Wednesday, January 3,

2018, there will be changes to the suite of Geostationary

Operational Environmental Satellite (GOES) products on the SBN. 

These changes are associated with the GOES East transition. 

This transition involves the phase-out of GOES-13 and the phase-

in of GOES-16 as GOES East.

 

The GOES-16 drift to 75.2 degrees West longitude completed

successfully on December 11, 2017.  On or shortly after

Thursday, December 14, 2017 at 1530UTC, it is anticipated that

dissemination of GOES-16 products will resume on the SBN.  In

general, the GOES-16 product flows will resume with the same

formats, cadence and headings that were in use during testing

throughout much of 2017, but there will be a few minor changes

(e.g., heading changes), as described herein, reflecting the new

location of GOES-16 and its imminent promotion to GOES East.

 

1. GOES-16 Advanced Baseline Imager (ABI) Sectorized Cloud and

Moisture Imagery (SCMI) will resume flowing on the SBN’s

GOES-R East channel (PID 108) on or after Thursday,

December 14, 2017, 1530UTC.  Refer to prior Service Change

Notice (SCN) 17-24 which first introduced actual GOES-16

SCMI to the SBN and which more fully describes these

products.  The WMO headers follow these patterns:

 

TIREii KNES – for East CONUS sectors (previously GOES-16

              CONUS sectors were distributed under the

              TIRCii KNES, for “center CONUS”)

TIRPii KNES – for Puerto Rico Regional sectors

TIRSii KNES – for East Full Disk sectors

TISjii KNES – for Mesoscale sectors

 

where j is the meso sector ID as defined in SCN 17-24, ii

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

KNES is a space, and KNES signifies that NESDIS is the

creating data center.

 

Product metadata will reflect the new location of GOES-16,

now on station, about to become GOES East.  The following

specific product_name global attribute metadata changes

will take effect with the resumption of the GOES-16 SCMI:

 

     TMESO becomes EMESO

     TCONUS becomes ECONUS

     TFD becomes EFD

     (PRREGI will not change)

 

The format of the GOES-16 SCMI imagery will remain netCDF4. 

The geographical coverage of the imagery will be similar to

that broadcast previously, except for changes due the

satellite’s relocation to 75.2 degrees West.  The mapping

of this imagery will be consistent with that of the imagery

disseminated on this channel between March and November

2017.  Although alternately-mapped “fixed-grid” GOES-16

imagery was evaluated on the SBN during late 2017 (on a

different SBN channel, see SCN 17-95), the transition of

GOES-16 SCMI to the fixed-grid will take place later,

during 2018, well after the GOES East transition.  NWS will

disseminate a Service Change Notice (SCN) describing the

SCMI fixed-grid transition before it takes place.

 

The GOES-16 ABI imagery has been evaluated and validated,

and is considered generally suitable for operational use.

However, validation efforts will continue through at least

early 2018.

 

2. GOES-16 Advanced Baseline Imager (ABI) Level 2 Derived

Products will resume flowing on the SBN’s Experimental

channel (PID 106) on or after Thursday, December 14, 2017,

1530UTC.  The same set of GOES-16 derived products that

were flowing on the SBN’s Experimental channel between June

and November 2017 will resume flowing there on or after

December 14, 2017.  Refer to SCNs 17-61 and 17-73 which

further describe these products: 

 

    Aerosol Detection (Smoke and Dust)

    Aerosol Optical Depth

    Cloud Top Phase

    Cloud Top Height

    Cloud Top Pressure

    Cloud Top Temperature

    Derived Stability Indices

    Total Precipitable Water

    Clear Sky Mask

    Fire/Hot Spot Characterization

    Land Surface (Skin) Temperature

    Cloud Optical Depth

    Cloud Particle Size Distribution

    Derived Motion Winds

 

The basic formats and headers of these products will not

change during the GOES East transition.  However, there

will be product-specific metadata changes within some of

these files that reflect the new location of GOES-16 and

its imminent transition to GOES East.

 

These GOES-16 derived products have been only partially

validated, and these products remain in a pre-operational

stage.  Validation efforts will continue well into 2018.  

 

These GOES-16 derived product flows are experimental.

Several of these products are likely to be discontinued

after an evaluation period. Others in this product set will

eventually be moved to other SBN channels and possibly

modified. It is envisioned that these changes will begin

during the first half of 2018.  NWS will disseminate a

Service Change Notice (SCN) describing these changes before

they occur.

 

3. Between Thursday, December 14 and Wednesday, December 20,

2017, NOAA will declare GOES-16 to be “GOES East,”

replacing GOES-13.  Please refer to the NESDIS GOES East

transition page for updates:

 

https://www.goes-r.gov/users/transitiontToOperations.html

 

During this transition period, GOES-13 products will

continue dissemination on the SBN, but only until on or

shortly after Wednesday, January 3, 2018, 15UTC.  On that

date, all remaining GOES-13 products on the SBN will be

discontinued, as described in the bullets below.

 

4. Effective on or after 15UTC Wednesday, January 3, 2018,

there will be changes to the GOES Automated Surface

Observing System (ASOS) Satellite Cloud Products (SCPs) on

the SBN, as described in SCN 17-127:

 

http://www.nws.noaa.gov/os/notification/scn17-127goes_cloud.htm

 

5. Effective on or after 15UTC Wednesday, January 3, 2018,

dissemination of GOES-13 GINI-format imagery will cease on

the SBN’s legacy-GOES channel (PID 102).  The affected

headers are:

    TIGEii KNES – East CONUS Sector, where ii = 01, 02,

                  04, 05, 06

    TIGPii KNES - Puerto Rico Regional Mercator, where

                  ii = 01, 02, 04, 05, 06

    TIGQii KNES - Puerto Rico National Polar Stereo

                  where ii = 01, 02 and 05

where ii corresponds to legacy imager channel, between the

ii and KNES is a space, and KNES signifies that NESDIS is

the creating data center.  The GOES-16 ABI SCMI products,

described in item 1, above, are replacements for these

products. 

 

6.    Effective on or after 15UTC Wednesday, January 3, 2018,

GOES-13 (legacy East satellite) imagery will be removed

from the following SBN legacy-GOES satellite composites:

    TIGNii KNES - Supernational Two-GOES Composites, where

                  where ii = 01, 02 and 05

    TIGFii KNES - Northern Hemisphere Two-GOES Composites,

                  where ii = 01, 02 and 05

    TICFii KNES - Multi-satellite Composites

                  where ii = 01, 02 and 04

and where ii corresponds to imager channel, between the ii

and KNES is a space, and KNES signifies that NESDIS is the

creating data center.

 

7.    Effective on or after 15UTC Wednesday, January 3, 2018,

dissemination of GOES-13 High-Density Winds will cease on

the SBN’s NMC/NWSTG channel (PID 101).  Potentially-

affected headers include:

 

    JACXii KNES

    JBCXii KNES

    JCCXii KNES

    JECXii KNES

    JGCXii KNES

    JHCXii KNES

    JICXii KNES

    JJCXii KNES

    JLCXii KNES

    JMCXii KNES

    JPCXii KNES

    JQCXii KNES

    JRCXii KNES

 

    where ii = 01, 11, 21, 31, etc. and with most GOES-13

    data messages being stored in products whose headers

    include ii values of 11, 21, 31 and 41.  Products with

    many of these headers will continue to flow with

    GOES-15 (West) High Density Winds.  Replacements for

    GOES-13 winds include the GOES-16 Derived Motion Winds 

    on the SBN’s experimental channel (see item 2, above).

 

8.    Effective on or after 15UTC Wednesday, January 3, 2018, the

basis for GOES East data in the NESDIS Global Hydro-

estimator Satellite Rainfall Estimates (on the SBN’s

NMC/NWSTG channel, PID 101) will change from GOES-13 to

GOES-16. Affected headers include: 

 

    ZETA96 KNES – six-hour total product

    ZETA97 KNES – three-hour total product

    ZETA98 KNES – one-hour total product

    ZETA99 KNES – fifteen-minute instantaneous product

 

Beyond this GOES East transition, additional GOES-16 products

are planned for SBN addition in early 2018.  Furthermore, GOES-S

is scheduled for launch by NOAA in March 2018, and products from

that satellite are planned for SBN addition beginning around May

2018.  Subsequent SCNs will describe these SBN product additions

in advance.
