Made ERI F1850C test work with gregorian calendar. #1437
Conversation
Several more changes are needed in cime, which will have a commit with the same title. This was tested using ERI_D_C3_CG_Ld8.ne30pg3_g17.F1850C_LTso.derecho_intel.cam-outfrq9s_leapday bld/namelist_files/use_cases/1850_cam_lt.xml Change year of some forcing files to 1852 so that leap day is handled. cime_config/testdefs/testmods_dirs/cam/outfrq9s_leapday/shell_commands Change start year to 2008, so that adding 4 (cime) yields a date that's within the time span of all of the forcing files.

I'm not sure that it will be acceptable to change the start year for this usecase, could you create a new usecase instead? 1852_cam_lt.xml perhaps

I've moved the new 1850_cam_lt.xml to leapyears_cam_lt.xml and reverted 1850_cam_lt.xml.
My push of these changes to my fork is failing with "The requested URL returned error: 500".
Should I push it somewhere else instead?

Why this change? Aren't these both leapyears?

Some of the external forcing files end in 2014. Since I'm changing the increment between the forecasts from 2 to 4 years I wanted to avoid problems from requesting a year that's beyond
the time span of those files. If that was too pre-emptive, I'll try a test with 2012.
The F1850 test of the gregorian calender in ERI requires that some forcing files provide data from 1852, while others can only provide 1850.

Motivation
Enable testing of the gregorian calendar for all of the start modes of a multi-instance case,
which will help ensure that DART can be used with every release (maybe tag) of CESM.
Description
The ERI test cannot use both the _CG (gregorian calendar) _C# (multi-instance) modifiers
because some conditionals in cime refer only to _C and unsuitable years are requested
from some CAM external forcing files.
This PR makes the test work for leap days.
It should require no changes to other uses of the ERI test,
but I have not run other tests because I don't know which tests to run.
Fixes
Several more changes are needed in cime, which are being handled in CIME PR #4899.
