Need to check Clocks/Calendars consistency in NEMS, MOM6 and CICE5
Closed this issue · 0 comments
This was originally reported for FV3ATM-MOM6-CICE5 in an email From @uturuncoglu on 6/25:
"It seems that all components have different behavior in setting calendar. So, as i know and see
MOM supports JULIAN, GREGORIAN, NOLEAP, THIRTY_DAY_MONTHS and NO_CALENDAR
CICE supports NOLEAP and GREGORIAN
FVGFS supports JULIAN, NOLEAP, THIRTY_DAY and NO_CALENDAR
So, the common choice seems NOLEAP but in NEMS side, use_leap_years is set to .true. in ice_in (and it seems that it is using gregorian) and calendar is set to 'julian' in model.configure. I think that julian need to be default for NEMS application and we need to set use_leap_years as .true. for CICE. Still there will be a inconsistency between JULIAN and GREGORIAN (in ice component) but i am not sure. The current NEMS system is set like that. Currently, i put fix to fv3gfs and mom side to be sure that we are using same calendar for all component and i'll make julian as default for FV3GFS application. I'll let you soon about that and you might start testing again."
@guillaumevernieres reported this for DATM-MOM6-CICE5 as well.
