Add ability to use noleap calendar with gregorian forcing files by dougiesquire · Pull Request #33 · ACCESS-NRI/libaccessom2

dougiesquire · 2026-08-07T06:37:47Z

This PR adds an optional calendar_override entry to date_manager_nml in accessom2.nml. When set, it takes precedence over the file-derived calendar for both the forcing and experiment clocks. Only calendar_override='noleap' with gregorian forcing files is supported - the existing noleap date-skipping logic already handles this by dropping Feb 29 records. The reverse (calendar_override='gregorian' with noleap forcing files) aborts for now.

Contributes to #32

…files Only adds support to override gregorian with noleap for now. The opposite aborts

- build_log_items was broken when - forcing_field_update-file/-index were renamed from field_update_data-file/-index in 0147d18 - forcing_update_field-datetime was dropped entirely in 8c3c7d9 - also fixes a small error left over from e51e6a8.

… function

Now checks both drop and replay leap year handling

- Updates to use JRA data on vk83/qv56 rather than ua8 - Removes JRA55_v1p4_IAF test config and updates JRA55_IAF and JRA55_IAF_SINGLE_FIELD to v1.4 - Updates instructions in README to use spack

I've fixed up the tests, which have been broken in a number of different ways for a long time. This included:

replacing a test utility function that was broken by libaccessom2 updates years ago (build_log_items)
refactoring the test_iaf_cycles test for better speed and test coverage
updating test configurations to use JRA data on vk83/qv56. Dropped the JRA55_v1p4_IAF and updated the other IAF configs to JRA55-do v1.6

I struggled getting a test environment with working versions of libaccessom2 and the necessary Python packages (netcdf is problematic). In the end, this was easiest with Spack and I've updated the README accordingly.

I've also added tests for the new calendar_override functionality. All tests now pass:

I ran three consecutive IAF cycles over the 5-year forcing period 1962-1966 (1964 is a leap year) with calendar_override = noleap. Output is here: /scratch/tm70/ds0092/access-om2/archive/om2_1deg_jra55_iaf+wombatlite

Some relevant snippets from libaccessom2 logs:

First cycle (output000/atmosphere/log/matmxx.pe00000.log):

accessom2_set_calendar: forcing files use calendar=gregorian but calendar_override=noleap was set. Feb 29 records will be dropped from the forcing data.

Also, ocean and ice diagnostics use noleap calendar:

		time:_Storage = "chunked" ;
		time:_ChunkSizes = 512 ;

		time:_NoFill = "true" ;
...

If it's not much work, the older version of the forcing data are in

/g/data/qv56/replicas/input4MIPs/CMIP6/OMIP/MRI/MRI-JRA55-do-1-3

and might be a usecase we care about at some point?

Are there tests for not setting effective_calendar too ?

Sorry - I mean - have you run OM2 with an unmodified calendar / not setting the new namelist value

Many of the tests do this. But I'll kick off a repro test with ACCESS-OM2

I added a JRA55_v1p3_IAF test configuration in d698a9e. The new tests all pass:

The default repro tests all pass: ACCESS-NRI/ACCESS-OM2#156

I also ran the 1deg RYF and IAF configurations for 1 month each and checked that the calendars are correct:

RYF

		time:calendar_type = "NOLEAP" ;
		time:calendar = "noleap" ;
		time:bounds = "time_bnds" ;
		time:_Storage = "chunked" ;
		time:_ChunkSizes = 512 ;
		time:_DeflateLevel = 5 ;
		time:_Endianness = "little" ;
		time:_NoFill = "true" ;
...

IAF

ncdump -hsc /g/data/tm70/ds0092/model/config/om2_testing_2/archive/output000/ocean/access-om2.mom5.3d.temp.1mon.mean.1958.nc
