Comment (by rahul.mahajan@…):

 Replying to [comment:75 fanglin.yang@…]:

 Thank you for your active participation in identifying and resolving the
 issues with cycling the surface variables. I will update the {{{FHCYC}}}
 variable value as per your suggestion.


 > Rahul, we (Xu, George, Helin and I myself ) are actively looking into
 the issue.  In the NEMS GFS world,  gcycle is called offline as part of
 the GDAS/GFS ANAL step to update sfcanl to all avaliable observations
 (including SST, snow, ice, soil moisture and vegetation greeness etc).
 Since in the FV3GFS world gcycle is no longer called, we need to make sure
 those updates are executed as part of the forecast at the first time step.
 Initialy investigation indicates that both the model code and scripts need
 to be updated.
 > I also noticed you have FHCYC=6 in your cycled experiment.  Please
 change it to 24.
