*Topic: *Suomi-NPP VIIRS Flight Software Update scheduled for April
19, 2016
*Date/Time Issued: *April 15, 2016 1905Z
*Product(s) or Data Impacted:* Suomi-NPP VIIRS data
*Date/Time of Initial Impact:* April 19, 2016 1301Z
*Date/Time of Expected End:* April 19, 2016 2004 UTC
*Length of Outage: * See Details
*Details and Specifics of Change: *On Tuesday April 19, 2016 the VIIRS
instrument will transition to a new flight software version (Ver.
0x4017). The flight software update is not expected to impact VIIRS
data; however, the transition to the new update will cause periodic
outages and will cause degradation of the Day-Night Band until
corresponding DNB Offset tables are loaded. Below is a list of
expected
impacts:
VIIRS Data may be missing or corrupt during the following VIIRS flight
software transition commanding windows:
SVL 23199: 13:01:39 - 13:15:51 UTC
SVL 23200: 14:43:40 - 14:57:15 UTC
SVL 23201: 16:27:01 - 16:39:07 UTC
SVL 23202: 18:10:31 - 18:21:10 UTC
SVL 23203: 19:53:18 - 20:04:19 UTC
VIIRS Data Impacts:
VIIRS will be commanded to OP_Day mode for two orbits as a necessary
step to minimize data impacts. Between 13:15 - 16:30 UTC, the VIIRS
instrument will be placed in OP_Day mode and will be not executing
day-to-night transitions. During that time, the visible bands will be
producing OP_D during the nominal OP_N portion of the orbits. There
will
be no loss of data during this time.
In addition, the VIIRS Day-Night Band will be degraded due to the
flight
software transition starting at approximately 14:45 UTC. The
degradation is expected to end by 18:20 UTC when all required DNB
tables
have been loaded and activated. VIIRS will return to full nominal
operations after 20:04 UTC.
