Topic: GOES-17 Data Outage and Degradation due to interleaving test May 11, 2022

Date/Time Issued: May 10, 2022 1240 UTC

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

Date/Time of Initial Impact: May 11, 2022 1700 UTC

Date/Time of Expected End: May 11, 2022 1730 UTC

Length of Outage: 30 minutes

Details/Specifics of Change:

On May 11, 2022 at 1700 UTC, an interleave test will be performed on the GOES-17 (GOES-West) GRB feed. The purpose of this test is to exercise the interleaving configuration before GOES-18 drifts from Test (89.5 degrees West) to near-West (136.8 degrees West). The test entails routing GOES-18 preliminary non-operational ABI data through the GOES-17 GRB to operational GOES-West GRB users.

Due to the configuration of the Ground System, GOES-17 data distributed to GOES-West GRB and PDA users is subject to possible degradation or incorrect metadata because of the unique configuration. Even though GLM and Space Weather products will be from GOES-17, it is subject to possible degradation or incorrect metadata. The metadata which may be incorrect includes the global attribute “orbital_slot” and other location-related metadata. More information on global attributes is available in the Product User’s Guide (PUG).

GOES-West GRB & PDA data should not be used operationally during this time period. This shall be considered an outage of GOES-West operational data.

| GOES-17 Data Quality
ABI | GLM | Space Weather
GOES-West GRB | OUTAGE (GOES-18 preliminary non-operational data) | Nominal but metadata may be incorrect | Nominal but metadata may be incorrect
GOES-West data in PDA, AWIPS, LZSS | Nominal | Nominal but metadata may be incorrect | Nominal but metadata may be incorrect

This test is subject to Critical Weather Day.
