GFSv15.3.0 production updates

[KateFriedman-NOAA]

Created release/gfs.v15.2.13 branch off operations branch for this work.

[KateFriedman-NOAA]

Created release tag for hand-off to NCO: RT-GFS-v15.2.13

Tag contains the following changes:

• bug fix to syndat_qctropcy.fd/qctropcy.f
• change to link_fv3gfs.sh to point to updated fix file set which contains updated syndat_stmnames file
• change to checkout.sh to update ProdGSI and EMC_post_gtg tags to latest ops versions

[KateFriedman-NOAA]

CDF drafted and sent to NCO.

[RussTreadon-NOAA]

NCO requested and EMC management agreed that GFS v15.2.13 and GFS v15.3.0 be merged into a single implementation package. As such GFS v15.3 development is now being tracked in issued #63. Commit c90ea4b updated sorc/checkout.sh in workflow branch release/gfs.v15.2.13 to point at the GFS v15.3.0 DA tag.

GFS v15.3 issue #37 may be closed and workflow branch feature/gfs.v15.3 removed as both are now obsolete.

Created release/gfs.v15.3.0 off release/gfs.v15.2.13 for hand-off.

[KateFriedman-NOAA]

Tested implementation instructions for NCO on Venus (used VLab workarounds) and modified link_fv3gfs.sh to use rsync instead of cp to make the FIX_DIR pickup faster/safer.

Updated implementation instructions with workaround details.

[KateFriedman-NOAA]

Implementation instructions prepared and tested with final package. Handing off to NCO today.

From the May 22nd RFC memo:

RFC 6893 – gfs v15.3.0 – On WCOSS, upgrade the GFS to v15.3.0. This new version implements the assimilation of COSMIC-2 GNSS-RO (Global Navigation Satellite System - Radio Occultation) data; fixes a bug in ‘sorc/syndat_qctropcy.fd/qctropcy.f’ which can cause bad tcvital records in the quality control step; updates ‘fix/fix_am/syndat_stmnames’, which is a fix file with updated tropical storm names; and enables alerting of GFS master files. To be implemented on May 26 at 1300Z.

[KateFriedman-NOAA]

Did comparison between release/gfs.v15.3.0 branch and the nwprod/gfs.v15.3.0 installation post-implementation on May 26th. Found final post-hand-off/pre-implementation changes and committed them to release/gfs.v15.3.0 branch at 737cfa8.

Will initiate PR to merge release/gfs.v15.3.0 into operations branch. Will run test on WCOSS to compare against ops before completing PR.

[KateFriedman-NOAA]

Reproduce test against ops successful, although I had to make local changes to handle the GDA structure change and point to updated obsproc versions. Performing PR to merge release/gfs.v15.3.0 branch into operations branch and then tag NCO-v15.3.0.

[KateFriedman-NOAA]

Submitted PR #79 and deleted release/gfs.v15.3.0 via PR. Created tag NCO-v15.3.0.
