Hello again,
As many of you have already seen, these changes were delayed from their
original timelines but took effect for GOES-16 yesterday at 18Z.
A new SCN just came out with additional details of this transition for both
GOES-East and GOES-West:
https://www.weather.gov/media/notification/pdf2/scn22-94_geo_spectral_coverage_goes-eastwest_aaa.pdf
A few important notes about these changes:
1. GOES-West implementation is scheduled for January 4th (no time listed)
2. These changes for both GOES-East AND GOES-West will temporarily be
rolled back between Jan. 31 and Mar. 6
3. On or about March 6th, these changes will be "reinstated permanently."
The justification for these changes remains the same, essentially that
removal of these products will reduce the bandwidth used on NOAAPort/SBN.
However, for those needing Southern Hemispheric GOES imagery there are a
few options:
1. ADDE feeds: Unidata makes available the full resolution Full-Disk
imagery over the ADDE feeds EAST/EASTALL and WEST/WESTALL.
2. IDD feeds:
- Unidata also makes available the full resolution Full-Disk imagery
on the SATELLITE (formerly DIFAX) IDD feed. Details, including example
pattern-actions, can be found here:
https://www.unidata.ucar.edu/data/goesr.html
- Additional Full-Disk imagery is available on the UNIWISC feed. The
difference here is bands 2, 8 and 13 (and only those bands) have been
rescaled to 4km; finer than SBN's 6km resolution but coarser than full
resolution (500m, 2km and 2km respectively). This may be a good
compromise
for those seeking S.Hemi data while needing to conserve
bandwidth. Details
on the UNIWISC feed can be found here:
https://www.unidata.ucar.edu/data/uniwisc.html
3. As noted in the above SCN, additional sources of GOES data may be
found in the below links:

- Note: These services are external to Unidata. Any support
requests for these services should go to their respective contacts.
These are no doubt impactful changes and the details can be confusing.
Please feel free to reach out if you have any questions.
Best,
