Topic:	NOAA-15 reaches 100,000 Revs on August 5, 2017 and will
roll over
in count to Rev =E2=80=9C1=E2=80=9D

Date/Time(UTC) Message Issued:	August 4, 2017 1640 UTC

Product(s) Involved/Affected:  All data and products from NOAA-15
(AVHRR,
AMSU, HIRS, SARSAT, & SEM) that rely on Rev Numbers.

Date/Time(UTC) of Initial Implementation:  August 5, 2017 ~0600 UTC

Date/Time(UTC) of Expected End:  Permanent

Length of Outage:  Permanent

Details/Specifics of Change:  The Joint Space Operations Center
(JSPOC) has
confirmed that the NOAA-15 Rev Odometer will roll over to 00001
not 00000.
Engineering has verified the roll over number by using 2li elements
from
DMSP OPS47 back from Aug of 2014.  Scheduling is performing
corrections to
products by hand for the week of Aug 1 since the Rev number change
happens
towards the end of a scheduling session versus producing two different
Satellite Operations Management System (SOMS) product sessions.
During the
following week, SOMS products should follow the normal scheduling
process.
In general, processes from spacecraft to users will function with the
possibility that some data will be lost on the transition roll over
Rev due
to processing checks.  However, efforts are being made to handling such
special cases. Other places where corrections are showing up are in
ancillary files and in tools that support this general process from
spacecraft to user.
Raw data from the spacecraft is only marked by time and file names are
added that can include Rev Numbers.  How these Rev numbers are
generated
for the file name may also be an issue.

POES scheduling, engineering, data ingest, user services, SARSAT,
ARGOS,
and product distribution are all aware of the NOAA-15 Rev Odometer roll
over.  This notice is to remind all that that this change in how Rev
numbers are reported for NOAA-15 will change in count but remain as a 5
digit number in both the 2li and 4li elements.	The roll over to
=E2=80=9C1=
=E2=80=9D
follows the launch protocol to not count Rev =E2=80=9C0=E2=80=9D.
