@KateFriedman-NOAA . A diff of the gsibec files in 20221031/ and 20240416/ shows the correct difference.

The gsibec namelist in 20240416/ comments out qoption=2, thereby defaulting the gsibec code to qoption=1. This is correct.

@RussTreadon-NOAA Great, thanks for confirming! I will proceed with syncing this update to the fix sets on the other supported platforms.

The fix version variable will need to be updated to gdas_gsibec_ver=20240416. Do you have plans to make that update within a future PR?

[RussTreadon-NOAA]

I did not plan on opening an issue and PR to update gdas_gsibec_ver to 20240416. I thought this would be accomplished via this issue. Your question suggests otherwise. I'll go ahead and open an issue and PR right now.

[KateFriedman-NOAA]

I'll go ahead and open an issue and PR right now.

Thanks @RussTreadon-NOAA ! If you didn't already have plans, I was going to offer to make the change but I'm happy to let you open a PR. Make me the reviewer and I'll get it approved and merged. We'll close this issue via that PR. Thanks!
