Update #2: Update to the correct the date of Issue
Update #1: This update provides a list of the GOES-W data content of each product distribution during interleave
Topic: GOES-18 Interleaving Test June 15, 2022
Date/Time Issued: May 24, 2022 2035 UTC
Product(s) or Data Impacted: GOES-17 (GOES-West) ABI, GLM, Space Weather
Date/Time of Initial Impact: June 15, 2022 1600 UTC
Date/Time of Expected End: June 15, 2022 2000 UTC
Length of Outage: 4 hours
Details/Specifics of Change:
On June 15, 2022 at 1600 UTC, a 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 on 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:
- G18 ABI L1b
- G17 GLM L2+
- G17 Space Wx L1b
PDA:
- 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 15th 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-Sept 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.
