Description

The GFSv16.3 is upgraded to GFSv16.3.5 to allow continued use of atmospheric motion vectors from the GOES-W satellite as GOES-18 replaces GOES-17 and to include the assimilation of VIIRS radiances from S-NPP and NOAA-20 (which were to be included in the v16.3 implementation but were omitted due to data availability issues).

Specifically, the following changes are made to the indicated GSI fix files:

  • global_satinfo.txt
    • Turn on VIIRS radiances from NPP and J1 for channels 12, 15, and 16
  • global_convinfo.txt
    • Turn off GOES-17 (271) AMV winds for types: 245 (IRLW), 246 (WVCT), and 247(WVCA) due to deteriorating conditions
    • Turn on GOES-18 (272) AMV winds for types: 245 (IRLW), 246 (WVCT), and 247(WVCA)

FYI @ADCollard

- NCO reviewed transfer parm files and provided a list of files that
were unused and could be removed.
- Removing unused transfer parm files in v16.3.5 to get ourselves
aligned with current GFS ops installs.

RFC Memo December 22nd, 2022:

RFC 10388 - On WCOSS2, implement GFS v16.3.5 which updates the
‘global_satinfo.txt’ and ‘global_convinfo.txt’ GSI fix files. This change is needed
to allow continued use of atmospheric motion vectors from the GOES-West
satellite as GOES-18 replaces GOES-17 and to include the assimilation of VIIRS
(Visible Infrared Imaging Radiometer Suite) radiances from S-NPP (Suomi
National Polar-orbiting Partnership) and NOAA-20. To be implemented on
January 4 from 2015Z to 2330Z.
