HRIT/EMWIN will take part in the GOES-18 Interleaving test on June 14th 2022

[Carl Reinemann]

This is just a reminder that on 14 June 2022, starting at 16:00 UTC and lasting 4 hours, HRIT/EMWIN will take part in the GOES-18 Interleaving test. GOES-18 CMI products will be distributed on the GOES-W HRIT/EMWIN feed in place of GOES-17 CMI products.

During the test period, short breaks in the GOES-W HRIT/EMWIN broadcast may occur.

On June 14, 2022 at 1600 UTC, a four hour test of the interleave configuration will be performed on the GOES-17 (GOES-West). This test is a user readiness opportunity to prepare for the operational interleave configurations that will be in place 24 hours per day during the two periods of August 1 - September 6 and October 15 - November 11, 2022.

At the time of the interleave test, GOES-18 will be located in a near-West orbital slot (136.8 degrees West), just 0.4 degrees from GOES-17 (at 137.2 degrees West).

The interleave configuration entails populating the operational GOES-17 GRB (GOES Rebroadcast) service with an “interleave” of GOES-18 ABI data (replacing the GOES-17 ABI data) and GOES-17 GLM and space weather data.

Here is the GOES-West data content of each product distribution service during interleave:

GRB: (netCDF file orbital slot will be "GOES West")

- G18 ABI L1b

- G17 GLM L2+

- G17 Space Wx L1b

PDA: ("GOES West" for products below)

- G18 ABI L1b, CMI (no L2+)

- G17 ABI L1b, CMI, L2+

- G17 GLM L1b, L2+

- G17 Space Wx L1b

- Note PDA cal/val subscriptions have additional G18 data access

CLASS:

- G17 ABI L1b, CMI, L2+

- G17 GLM L1b, L2+

- G17 Space Wx L1b

- Note CLASS cal/val subscriptions have additional G18 data access

NODD (formerly BDP):

- G18 ABI Rad, CMI

- G17 ABI Rad, CMI, L2+

- G17 GLM L2+

- G17 Space Wx L1b

HRIT/EMWIN:

- G18 ABI CMI

- G17 ABI L2+

GNC-A:

- G18 ABI CMI

AWIPS:

- G18 ABI SCMI

- G17 GLM L2+

During the June 14th test, GOES-18 ABI data will still be at a “Beta” level of maturity, minimally validated, and may contain significant errors. Nonetheless, GOES-18 ABI data obtained during this test will be advised for operational use, and may be shared without restriction.

During the Aug-Sep and Oct-Nov interleave periods, GOES-18 ABI data will be at “Provisional” level of maturity, fit for operational use and may be shared without restriction.

Note regarding GOES-17 ABI during interleave: GOES-17 ABI will be operating continuously until the GOES-West transition from GOES-17 to GOES-18 in January, 2023. Continuous GOES-17 ABI operations will include the June 14th interleave test and the Aug-Sep and Oct-Nov interleave periods when GOES-17 ABI will have multiple focal plane module temperature (FPM) mitigations including the cooling timeline and multiple FPM set points adjustments.
