Subject: Changes to GOES/ASOS Cloud Product on Satellite
Broadcast Network (SBN or NOAAPort) Effective
January 2, 2018
Effective on or after 15 UTC Tuesday, January 2, 2018, there
will be changes to the Geostationary Operational Environmental
Satellite (GOES) Automated Surface Observing System (ASOS)
Satellite Cloud Product (SCP) on the SBN.
The changes are associated with the replacement of GOES-13 with
GOES-16 as GOES East on or about December 18, 2017, and the
subsequent transition of GOES-13 to storage mode beginning on or
after January 2, 2018. As described below, SCP coverage for some
GOES East stations will temporarily cease and the basis of the
SCP products for other GOES East stations will change.
The GOES-ASOS SCP product is ideally produced from GOES Sounder
data but it can also be produced from GOES imager data. Since
the GOES-13 sounder degraded in 2015, the GOES East SCP product
has been based on GOES-13 imager data. The GOES-15 (GOES West)
sounder continues to function normally and the GOES West SCP
continues to be produced from GOES West sounder data.
GOES-13 product flows will be disabled on or about January 2,
2018; however, the GOES-16 replacement product for the SCP will
not reach maturity for operational use before June 2018.
Therefore, when the GOES-13 SCP ceases dissemination, the GOES
ASOS cloud product for the East stations will change in two
1. Data from the GOES-15 (West) imager will be used to
generate the SCP product for GOES East stations, but only
for stations that are adequately covered by the GOES-15
imager. This substitution of GOES-15 imager data, as a
basis for the GOES East stations, will be possible only in
the western areas of the GOES East coverage.
2. For GOES East stations outside the area where the GOES-15
(West) imager can provide the SCP, dissemination of the SCP
will cease on or about January 2, 2018. This loss of SCP
coverage will continue until the GOES-16 SCP reaches a
level of maturity such that it can disseminate on an
The SCP headers, AWIPS IDs, and expected impacts are as follows:
WMO ID AWIPS ID REGION IMPACT CODE
TCUS40 KNES SCPER1 Eastern Region #1 1
TCUS41 KNES SCPCR1 Central Region #1 2
TCUS42 KNES SCPSR1 Southern Region #1 3
TCUS43 KNES SCPWR1 Western Region #1 4
TCUS51 KNES SCPCR2 Central Region #2 5
TCUS52 KNES SCPSR2 Southern Region #2 6
TCUS53 KNES SCPWR2 Western Region #2 4
TCUS62 KNES SCPSR3 Southern Region #3 1
The Impact Codes, above, refer to product coverage between the
cessation of GOES-13 SCP distribution (approximately January 2,
2018) and the activation of the GOES-16 SCP (no sooner than June
2018), as follows:
1. Most or all SCP suspended.
2. Some SCP suspended; SCP for numerous stations provided by
GOES-15 imager data.
3. SCP suspended for numerous eastern stations; SCP for some
western stations provided by GOES-15 imager data.
4. No data suspended and no change to data during transition.
GOES-15 sounder data will continue to be used throughout.
5. No data suspended. SCPs for most stations continue to be
provided by GOES-15 sounder data; SCP for remaining eastern
stations to be provided by GOES-15 imager data.
6. Little or no data loss. SCPs for western stations continue
to be provided by GOES-15 sounder data; SCP for remaining
eastern stations to be provided by GOES-15 imager data.
Refer to the following supplement for further information about
the geographical coverage of the SCPs and the specific SCP
stations affected by this change.
