How to change forcing to daily data in Climatological simulation

I just started learning to use Croco,I want to use Croco to simulate the Kuroshio extension,but I do see an extension of the Kuroshio moving north.I use the make_forcing.m,make_ini.m,make_bry.m files to create initial fields as well as boundary and forcing fields,I interpolated croco_ini.nc and croco_bry.nc files and replaced the data in them with other data sets, but my frc file uses the default COADS05 data. I suspect that the northward shift of the Kuroshio extension is the reason for the forcing field, so I want to replace the forcing field with a higher frequency(daily). Would you please ask me how to replace the high-frequency forcing field?

Of course, it may not be the reason. If you know the reason, can you give me some suggestions?
Thank you very much!
