### Daily cycle or Daily averaged light
By Default, MEDUSA should be run with Daily averaged light.
All chl and Production paramaters are tuned for an averaged light.
You can double check it's done this way by making sure that `ln_msa_avgqsr` in nammsa_ctl is set to `.true.`
If you use the fully coupled chl-light scheme, make also sure that `ln_trcdc2dm` is set to `.true.` (dc2dm for "Daily Cycle to Daily Mean" \

If, for some reason you need the light daily cycle, set `ln_msa_avgqsr` and `ln_trcdc2dm` to `.false.` (ln_trcdc2dm, should not be necessary, but, i mention it just for good measure - can't be too prudent)
