RFC 13485 - annual CO2 update and PlanetIQ assimilation
On WCOSS2, upgrade the GFS to v16.3.20. This includes the following changes:
● install 2025 carbon dioxide (CO2) fix file updates before the start of the new year;
● turn on assimilation of PlanetiQ GPS Radio Occultation (GPS-RO) data;
● load the cmdaccel module at the start of wave point postprocessor jobs to stabilize runtime.
Implemented on December 9 during the 12Z cycle.
