RTOFS showing strong salinity bias #32

Open DanIredell-NOAA opened 1 year ago

DanIredell-NOAA commented 1 year ago

RTOFS is showing a salinity drift (bias). This can be caused by HYCOM or NCODA or one exacerbated by the other.

RTOFS - modify archv_inc to use layers NCODA (3Dvar) - create layers for restart

Simulation paraB will test these changes

DanIredell-NOAA commented 1 year ago

Stopped paraB. New codes for NCODA implemented will use ADT option for ssh. This run is called paraD.

DanIredell-NOAA commented 1 year ago

Alternately this is a HYCOM layer thickness problem (the cause instead of the symptom). Restarted paraD with another update for NCODA.

DanIredell-NOAA commented 1 year ago

Stopped paraD because of failure on 20230501 in the Sulu Sea (near Philippines). More analysis is needed of what was the cause of this. Also will need more/better diagnostics of the run to foresee if the run is starting to show tendencies of this condition.
