Subject: Add Geostationary Operational Environmental
 Satellite-16 (GOES-East) Level 2 Derived Products
 to the SBN or NOAAPort effective February 28, 2018

Effective on or after 15 UTC Wednesday, February 28, 2018,
additional GOES-16 (GOES-East) Level 2 Derived Products will be
added to the Satellite Broadcast Network (SBN) also known as
NOAAPort. These products are based on the GOES-16 Advanced
Baseline Imager (ABI). These GOES-16 derived products have been
only partially validated and remain in a pre-operational stage.
Validation efforts will continue well into this calendar year.

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. These
products are being added to enable the testing of networks and
systems with actual GOES-16 data and so that users will be able
to evaluate the products during this validation/test period.

NOAA does not recommend using these preliminary products in
operational forecast processes, especially during the
validation/test period. Any downstream postings of these data
should clearly convey their preliminary non-operational status.
Furthermore, this data stream may be subject to temporary
unannounced data outages and modifications during this
validation and testing period. One or more follow-on notices
will provide information on the progress and conclusion of the
validation period.

The derived products described, below, join other GOES-16
derived products already on the SBN, such as those described in
Service Change Notice 17-135:

http://www.nws.noaa.gov/os/notification/scn17-
135goes16derived_products.htm

The new GOES-16 level 2 derived products, the first 11
characters of their WMO headers, and their geographical regions
of coverage are as follows:

GOES-16 Product       WMO Header    Regions
---------------      ----------    -------
Legacy Vertical Temperature ProfileIXTQ99 KNES  C
Legacy Vertical Moisture Profile   IXTP99 KNES     C

Notes on table, above:
1. Region codes refer to GOES-16 geographical sectors, where F
refers to ABI Full Disk, C refers to ABI CONUS, and M refers to
ABI mesoscale (currently, Full Disk and Meso are not applicable
and will not be transmitted).
2. KNES signifies that NOAA/NESDIS originated the products.
3. The file format for these products is netCDF4

Approximate hourly product counts and hourly volumes for the new
GOES-16 (GOES-East) Level 2 derived products are as follows:

GOES-16 Product      Hourly Count    Hourly Volume
---------------      -------------   -------------
Legacy Vert Temp Profile    2/hour       62 Mbytes/hour
Legacy Vert Moisture Profile 2/hour        62 Mbytes/hour

Product counts and volumes will vary due to ABI mode changes,
diurnal variations, file-compression variability, and
other factors.

For the foreseeable future, the SBN`s Experimental channel
(PID 106) will be used to disseminate these GOES-16 Level 2
derived products; however, NWS anticipates the SBN suite of
GOES-16 products described here will evolve.

Future Service Change Notices will provide further information
on the GOES-16 derived product transitions to operations and on
continuing product validation plans.

Additional information about the flow of GOES-16 products on the
SBN has been posted at the following website 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.
