Topic: New Sensor Processing System (SPS) software release

Date/Time Issued: April 15, 2014 1500 UTC

Product(s) or Data Impacted: GOES-13 (GOES-East) Imager and Sounder
data

Date/Time of Initial Impact: April 22, 2014 1535 UTC

Date/Time of Expected End: Permanent change

Length of Outage: Permanent change

Details/Specifics of Change: On April 22, 2014, a new Sensor Processing
System (SPS) software version (10.4.1) will be released for GOES-13
(GOES-East). The new SPS release 10.4.1 replaces version 10.2 and
corrects
the following issues observed with GOES-13 (GOES-East) Imager and
Sounder:

GOES-13 (GOES-East) IR Channels 2 (3.9 um) and 4 (10.7 um) registration
difference was discovered to be 1 pixel or greater at certain times
of day.
This can cause false fog data which uses the difference between
these two
channels. A registration correction algorithm was developed into SPS
v10.4.1 which shifts one of these channels towards the other based on
whichever is closer to visible channel. When channel-2 needs correction
(GOES-13) it is shifted one full pixel whenever the difference is
more than
0.5 pixel.

GOES-13 (GOES-East) Sounder Dropped Pixel Correction
The last significant element to be included in this software release
is the
implementation of an algorithm which utilizes a second sync-bit code
if the
first is not found. This algorithm will allow the software to
recover what
was previously considered as lost data blocks which are depicted
as missing
pixels (black spots) since July 2014.
