SUBJECT - GOES-17 (GOES-West) ABI Cooling Timeline Mode 3 Test

TEST INFORMATION
- Impact(s): GOES-17 ABI Imagery and Level 2 Products
- Start Time: December 10, 2019 1800Z
- Expected End:  December 11, 2019 2000Z
- Event Duration: Two 2-hour events (1800Z -to- 2000Z)

TEST DESCRIPTION
On Tuesday December 10, 2019 and Wednesday December 11,
2019, NESDIS will conduct two hours (1800-2000 UTC each day)
of a  GOES-17 ABI cooling timeline test using Mode-3.  This test
is planned to investigate the ground system throughput for L2
algorithms.

The test will be a variation of Mode 3 (“Flex Mode” uploaded as
timelineID=3) where GOES-17 ABI will generate a single full disk
once per 15 minutes and a single mesoscale domain sector once
per 1 minute. The CONUS domain and usual second mesoscale domain
sector will not be scanned during the timeline as those periods
will be used for cooling.

Product availability will occur every 15 minutes with timestamps
of HH:05, HH:20, HH:35, and HH:50 (with HH:05 representing data
collected from HH:50 through HH:05 and HH:20 representing data
collected from HH:05 through HH:20, etc.) for each hour from
1800-2000 UTC on December 10 and 11.

GOES-17 ABI will return to nominal Mode 6 operations including the
ability to make two mesoscale domain sector requests at 2000 UTC
on each of the two days.  INR and radiometric calibration will be
maintained throughout the data outage.

This test will be postponed in the event of Critical Weather Day
declaration over the test period. The test will slip one business
day at a time until it does not conflict with CWD declaration.

These test activities are specific to ABI.  All other GOES-17
spacecraft and instrument (EXIS, GLM, Magnetometer, SEISS, SUVI)
activities will remain nominal for the duration of these tests.
