Topic: GOES-18 Interleaving Test June 14, 2022

 

Date/Time Issued: June 13, 2022 1224 UTC

 

Product(s) or Data Impacted: GOES-17 (GOES-West) ABI, GLM, Space Weather 

 

Date/Time of Initial Impact: June 14, 2022 1600 UTC

 

Date/Time of Expected End: June 14, 2022 2000 UTC 

 

Length of Outage: 4 hours

 

Details/Specifics of Change:

 

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.  See this table for the key to GRB Spacecraft IDs and Metadata:  https://www.ospo.noaa.gov/Operations/GOES/documents/GRB%20Interleave%20Spacecraft%20ID's%20and%20Metadata.pdf

 

In order to ensure continuity of GOES-West ABI operations, GRB users are advised to ensure their end-processing will accept a different ABI platform ID (G18 rather than G17) and instrument ID (FM3 rather than FM2). More information on global attributes is available in the Product User’s Guide (PUG) Volume 4 for GRB: https://www.goes-r.gov/users/docs/PUG-GRB-vol4.pdf

 

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.

 

This test is subject to delay in the event of a Critical Weather Day declaration.

 

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.
